> **Warning**
> If you are looking for our next major version `6.x.x` which is requiring **Java 11** as mimimal version and which is using Jakarta EE components using the `jakarta.*` packages instead of `javax.*` check the [`6.x` branch](https://github.com/gitlab4j/gitlab4j-api/tree/6.x).
> The `6.x.x` version is the one you need if you are using Spring Boot 3 and Spring Framework 6.0, .
## GitLab Server Version Support
GitLab4J-API supports version 11.0+ of GitLab Community Edition [(gitlab-ce)](https://gitlab.com/gitlab-org/gitlab-ce/) and GitLab Enterprise Edition [(gitlab-ee)](https://gitlab.com/gitlab-org/gitlab-ee/).
GitLab released GitLab Version 11.0 in June of 2018 which included many major changes to GitLab. If you are using GitLab server earlier than version 11.0, it is highly recommended that you either update your GitLab install or use a version of this library that was released around the same time as the version of GitLab you are using.
**NOTICE**:
As of GitLab 11.0 support for the GitLab API v3 has been removed from the GitLab server (see https://about.gitlab.com/2018/06/01/api-v3-removal-impending/). Support for GitLab API v3 will be removed from this library sometime in 2019. If you are utilizing the v3 support, please update your code to use GitLab API v4.
---
## Using GitLab4J-API
### **Java 8 Requirement**
As of GitLab4J-API 4.8.0, Java 8+ is now required to use GitLab4J-API.
### **Javadocs**
Javadocs are available here: [](https://javadoc.io/doc/org.gitlab4j/gitlab4j-api)
### **Project Set Up**
To utilize GitLab4J™ API in your Java project, simply add the following dependency to your project's build file:
**Gradle: build.gradle**
```java
dependencies {
...
compile group: 'org.gitlab4j', name: 'gitlab4j-api', version: '5.6.0'
}
```
**NOTE:** Pulling dependencies may fail when using Gradle prior to 4.5. See [Gradle issue 3065](https://github.com/gradle/gradle/issues/3065#issuecomment-364092456)
**Maven: pom.xml**
```xml
org.gitlab4j
gitlab4j-api
5.6.0
```
**Jbang:**
[Jbang](https://www.jbang.dev/) is very convinient to run scripts writen in Java having dependencies on third party libraries.
Just add this line at the top of your script:
```java
//DEPS org.gitlab4j:gitlab4j-api:5.6.0
```
**Ivy and SBT**
There have been reports of problems resolving some dependencies when using Ivy or SBT, for help resolving those issues see:
JAX-RS API Issue #571
JAX-RS API Issue #572
### **Lastest version**
While we are frequently creating releases, you might be interested by a feature that has not been published yet.
You can use jars created by [jitpack](https://jitpack.io/) to get the newest version.
**Usage with gradle:**
```gradle
repositories {
mavenCentral()
maven {
url "https://jitpack.io"
content {
includeGroup "com.github.gitlab4j"
}
}
}
dependencies {
// ...
implementation 'com.github.gitlab4j:gitlab4j-api:main-SNAPSHOT'
// ...
}
```
**Usage with maven:**
```xml
jitpack.io
https://jitpack.io
com.github.gitlab4j
gitlab4j-api
main-SNAPSHOT
```
**Usage with jbang:**
You just need to declare the dependency like this, instead of using the maven coordinates:
```java
//DEPS https://github.com/gitlab4j/gitlab4j-api/tree/main#:SNAPSHOT
```
**Using a specific commit**
Version `main-SNAPSHOT` indicates that you would like to get the latest of the `main` branch.
You can also point to a specific commit:
```gradle
dependencies {
implementation 'com.github.gitlab4j:gitlab4j-api:6561c93aaf'
}
```
```xml
com.github.gitlab4j
gitlab4j-api
6561c93aaf
```
```java
//DEPS https://github.com/gitlab4j/gitlab4j-api/tree/6561c93aafa6bf35cb9bad0617127a0c249a8f9f
```
---
### **Usage Examples**
GitLab4J-API is quite simple to use, all you need is the URL to your GitLab server and the Personal Access Token from your GitLab Account Settings page. Once you have that info it is as simple as:
```java
// Create a GitLabApi instance to communicate with your GitLab server
GitLabApi gitLabApi = new GitLabApi("http://your.gitlab.server.com", "YOUR_PERSONAL_ACCESS_TOKEN");
// Get the list of projects your account has access to
List projects = gitLabApi.getProjectApi().getProjects();
```
You can also login to your GitLab server with username, and password:
```java
// Log in to the GitLab server using a username and password
GitLabApi gitLabApi = GitLabApi.oauth2Login("http://your.gitlab.server.com", "username", "password");
```
As of GitLab4J-API 4.6.6, all API requests support performing the API call as if you were another user, provided you are authenticated as an administrator:
```java
// Create a GitLabApi instance to communicate with your GitLab server (must be an administrator)
GitLabApi gitLabApi = new GitLabApi("http://your.gitlab.server.com", "YOUR_PERSONAL_ACCESS_TOKEN");
// sudo as as a different user, in this case the user named "johndoe", all future calls will be done as "johndoe"
gitLabApi.sudo("johndoe")
// To turn off sudo mode
gitLabApi.unsudo();
```
---
### **Setting Request Timeouts**
As of GitLab4J-API 4.14.21 support has been added for setting the conect and read timeouts for the API client:
```java
GitLabApi gitLabApi = new GitLabApi("http://your.gitlab.com", "YOUR_PERSONAL_ACCESS_TOKEN", proxyConfig);
// Set the connect timeout to 1 second and the read timeout to 5 seconds
gitLabApi.setRequestTimeout(1000, 5000);
```
---
### **Connecting Through a Proxy Server**
As of GitLab4J-API 4.8.2 support has been added for connecting to the GitLab server using an HTTP proxy server:
```java
// Log in to the GitLab server using a proxy server (with basic auth on proxy)
Map proxyConfig = ProxyClientConfig.createProxyClientConfig(
"http://your-proxy-server", "proxy-username", "proxy-password");
GitLabApi gitLabApi = new GitLabApi("http://your.gitlab.com", "YOUR_PERSONAL_ACCESS_TOKEN", null, proxyConfig);
// Log in to the GitLab server using a proxy server (no auth on proxy)
Map proxyConfig = ProxyClientConfig.createProxyClientConfig("http://your-proxy-server");
GitLabApi gitLabApi = new GitLabApi("http://your.gitlab.com", "YOUR_PERSONAL_ACCESS_TOKEN", null, proxyConfig);
// Log in to the GitLab server using an NTLM (Windows DC) proxy
Map ntlmProxyConfig = ProxyClientConfig.createNtlmProxyClientConfig(
"http://your-proxy-server", "windows-username", "windows-password", "windows-workstation", "windows-domain");
GitLabApi gitLabApi = new GitLabApi("http://your.gitlab.com", "YOUR_PERSONAL_ACCESS_TOKEN", null, ntlmProxyConfig);
```
See the Javadoc on the GitLabApi class for a complete list of methods accepting the proxy configuration (clientConfiguration parameter)
---
### **GitLab API V3 and V4 Support**
As of GitLab4J-API 4.2.0 support has been added for GitLab API V4. If your application requires GitLab API V3,
you can still use GitLab4J-API by creating your GitLabApi instance as follows:
```java
// Create a GitLabApi instance to communicate with your GitLab server using GitLab API V3
GitLabApi gitLabApi = new GitLabApi(ApiVersion.V3, "http://your.gitlab.server.com", "YOUR_PRIVATE_TOKEN");
```
**NOTICE**:
As of GitLab 11.0 support for the GitLab API v3 has been removed from the GitLab server (see https://about.gitlab.com/2018/06/01/api-v3-removal-impending/). Support for GitLab API v3 will be removed from this library sometime in 2019. If you are utilizing the v3 support, please update your code to use GitLab API v4.
---
### **Logging of API Requests and Responses**
As of GitLab4J-API 4.8.39 support has been added to log the requests to and the responses from the
GitLab API. Enable logging using one of the following methods on the GitLabApi instance:
```java
GitLabApi gitLabApi = new GitLabApi("http://your.gitlab.server.com", "YOUR_PERSONAL_ACCESS_TOKEN");
// Log using the shared logger and default level of FINE
gitLabApi.enableRequestResponseLogging();
// Log using the shared logger and the INFO level
gitLabApi.enableRequestResponseLogging(java.util.logging.Level.INFO);
// Log using the specified logger and the INFO level
gitLabApi.enableRequestResponseLogging(yourLoggerInstance, java.util.logging.Level.INFO);
// Log using the shared logger, at the INFO level, and include up to 1024 bytes of entity logging
gitLabApi.enableRequestResponseLogging(java.util.logging.Level.INFO, 1024);
// Log using the specified logger, at the INFO level, and up to 1024 bytes of entity logging
gitLabApi.enableRequestResponseLogging(yourLoggerInstance, java.util.logging.Level.INFO, 1024);
```
---
### **Results Paging**
GitLab4J-API provides an easy to use paging mechanism to page through lists of results from the GitLab API.
Here are a couple of examples on how to use the Pager:
```java
// Get a Pager instance that will page through the projects with 10 projects per page
Pager projectPager = gitLabApi.getProjectApi().getProjects(10);
// Iterate through the pages and print out the name and description
while (projectPager.hasNext()) {
for (Project project : projectPager.next()) {
System.out.println(project.getName() + " -: " + project.getDescription());
}
}
```
As of GitLab4J-API 4.9.2, you can also fetch all the items as a single list using a Pager instance:
```java
// Get a Pager instance so we can load all the projects into a single list, 10 items at a time:
Pager projectPager = gitlabApi.getProjectsApi().getProjects(10);
List allProjects = projectPager.all();
```
---
### **Java 8 Stream Support**
As of GitLab4J-API 4.9.2, all GitLabJ-API methods that return a List result have a similarlly named method that returns a Java 8 Stream. The Stream returning methods use the following naming convention: ```getXxxxxStream()```.
**IMPORTANT**
The built-in methods that return a Stream do so using ___eager evaluation___, meaning all items are pre-fetched from the GitLab server and a Stream is returned which will stream those items. **Eager evaluation does NOT support parallel reading of data from ther server, it does however allow for parallel processing of the Stream post data fetch.**
To stream using ___lazy evaluation___, use the GitLab4J-API methods that return a ```Pager``` instance, and then call the ```lazyStream()``` method on the ```Pager``` instance to create a lazy evaluation Stream. The Stream utilizes the ```Pager``` instance to page through the available items. **A lazy Stream does NOT support parallel operations or skipping.**
#### **Eager evaluation example usage:**
```java
// Stream the visible projects printing out the project name.
Stream projectStream = gitlabApi.getProjectApi().getProjectsStream();
projectStream.map(Project::getName).forEach(name -> System.out.println(name));
// Operate on the stream in parallel, this example sorts User instances by username
// NOTE: Fetching of the users is not done in parallel,
// only the sorting of the users is a parallel operation.
Stream stream = gitlabApi.getUserApi().getUsersStream();
List users = stream.parallel().sorted(comparing(User::getUsername)).collect(toList());
```
#### **Lazy evaluation example usage:**
```java
// Get a Pager instance to that will be used to lazily stream Project instances.
// In this example, 10 Projects per page will be pre-fetched.
Pager projectPager = gitlabApi.getProjectApi().getProjects(10);
// Lazily stream the Projects, printing out each project name, limit the output to 5 project names
projectPager.lazyStream().limit(5).map(Project::getName).forEach(name -> System.out.println(name));
```
---
### **Java 8 Optional Support**
GitLab4J-API supports Java 8 Optional<T> for API calls that result in the return of a single item. Here is an example on how to use the Java 8 Optional<T> API calls:
```java
Optional optionalGroup = gitlabApi.getGroupApi().getOptionalGroup("my-group-path");
if (optionalGroup.isPresent())
return optionalGroup.get();
return gitlabApi.getGroupApi().addGroup("my-group-name", "my-group-path");
```
---
### **Issue Time Estimates**
GitLab issues allow for time tracking. The following time units are currently available:
* months (mo)
* weeks (w)
* days (d)
* hours (h)
* minutes (m)
Conversion rates are 1mo = 4w, 1w = 5d and 1d = 8h.
---
## Making API Calls
The API has been broken up into sub API classes to make it easier to consume and to separate concerns. The GitLab4J sub API classes typically have a one-to-one relationship with the API documentation at [GitLab API](https://docs.gitlab.com/ce/api/). Following is a sample of the GitLab4J sub API class mapping to the GitLab API documentation:
```org.gitlab4j.api.GroupApi``` -> https://docs.gitlab.com/ce/api/groups.html
```org.gitlab4j.api.MergeRequestApi``` -> https://docs.gitlab.com/ce/api/merge_requests.html
```org.gitlab4j.api.ProjectApi``` -> https://docs.gitlab.com/ce/api/projects.html
```org.gitlab4j.api.UserApi``` -> https://docs.gitlab.com/ce/api/users.html
### **Available Sub APIs**
The following is a list of the available sub APIs along with a sample use of each API. See the Javadocs for a complete list of available methods for each sub API.
