# Redmine/Chiliproject Java API.



* Uses Redmine's REST API (don't forget to enable it in Redmine server settings).

* Does not require any plugins installed on Redmine/Chiliproject server.

* Requires JVM 11 or newer.

* Supports HTTP proxy

* Supports GZipped responses from servers

* Uses SLF4J for logging. Provide [your own SLF4J binding](http://www.slf4j.org/codes.html#StaticLoggerBinder)

* [Supported Redmine versions] (https://github.com/taskadapter/redmine-java-api/wiki/Redmine-versions-compatibility)

* Available in Maven Central (binary, sources, javadocs).



Gradle dependency:



    dependencies {

        compile 'com.taskadapter:redmine-java-api:'

    }



Check the [latest release version in Maven Central](http://search.maven.org/#search%7Cgav%7C1%7Cg%3A%22com.taskadapter%22%20AND%20a%3A%22redmine-java-api%22)



# Sample code.



# Obtain `transport` required for fluent-style calls



The new fluent-style API (v. 4.x) requires a `transport` instance for most calls. 

First, create an instance of RedmineManager and then obtain its transport:



    RedmineManager mgr = RedmineManagerFactory.createWithApiKey(uri, apiAccessKey);

    Transport transport = mgr.getTransport();



## Get list of issues



    String uri = "https://www.hostedredmine.com";

    String apiAccessKey = "somekey";

    String projectKey = "taskconnector-test";

    Integer queryId = null; // any



    RedmineManager mgr = RedmineManagerFactory.createWithApiKey(uri, apiAccessKey);

    // override default page size if needed

    mgr.setObjectsPerPage(100);

    List issues = mgr.getIssueManager().getIssues(projectKey, queryId);

    for (Issue issue : issues) {

        System.out.println(issue.toString());

    }



## Multi-values search for issues



    Params params = new Params()

                .add("set_filter", "1")

                .add("f[]", "summary")

                .add("op[summary]", "~")

                .add("v[summary]", "another")

                .add("f[]", "description")

                .add("op[description]", "~")

                .add("v[description][]", "abc");



    result = issueManager.getIssues(params);

    

Redmine searches for "Open" issues by default. You can specify "all" in your Map if you want:



    params.put("status_id", "*");    



## Get related objects when retrieving issues

    

    issue = issueManager.getIssueById(123, Include.journals, Include.relations, Include.attachments, 

                              Include.changesets, Include.watchers);

    journals = issue.getJournals();



## Create an issue



    RedmineManager mgr = RedmineManagerFactory.createWithApiKey(uri, apiAccessKey);	

	Version ver = new Version().setId(512);

	IssueCategory cat = new IssueCategory(transport).setId(673);

    ProjectManager projectManager = manager.getProjectManager();

    Project projectByKey = projectManager.getProjectByKey("testid");



    Issue issue = new Issue(mgr.getTransport(), projectId)

        .setSubject("test123")

	    .setTargetVersion(ver)

	    .setCategory(cat);

        .setProjectId(projectId)

        .create();

    

## Get issue by Id

    Issue retrievedIssue = issueManager.getIssueById(123);



## Set custom field value on issue 

    Issue issue = ...

    List customFieldDefinitions = mgr.getCustomFieldManager().getCustomFieldDefinitions();

    // sample implementation for getCustomFieldByName() is in CustomFieldResolver (test class).

    // in prod code you would typically know the custom field name or id already 

    CustomFieldDefinition customField1 = getCustomFieldByName(customFieldDefinitions, "my_custom_1");

    String custom1Value = "some value 123";

    issue.addCustomField(CustomFieldFactory.create(customField1.getId(), customField1.getName(), custom1Value));

    issueManager.update(issue);



## Create project



	Project project = new Project(transport)

 				.setName("Upload project")

   				.setIdentifier("uploadtmpproject")

   				.create();



## Get all projects



    List projects = mgr.getProjectManager().getProjects();



## Free-form search for users

    Map params = new HashMap<>();

    params.put("name", name);

    List list = userManager.getUsers(params);



## Create a group and add user to it



    Group group = new Group(transport)

        .setName("group")

        .create();

        

    User user = new User(transport).set(...)

        .create();

        

    userManager.addUserToGroup(user, group);



##  Delete user

    

    user.delete();



## Get time entries

    TimeEntryManager timeEntryManager = redmineManager.getTimeEntryManager();

    final Map params = new HashMap<>();

    params.put("project_id", projectId);

    params.put("activity_id", activityId);

    final List elements = timeEntryManager.getTimeEntries(params);



## Using a custom (e.g. self-signed) SSL certificate

Supposing you have:

* caTrustStore: a Collection\ object that has the custom CAs to use



Then the following function will return a RedmineManager object that uses those TrustStores

to connect to Redmine:



    public RedmineManager connectToRedmine(String apiAccessKey, String url) throws IOException {

        try {

            ClientConnectionManaget connectionManager =

                    RedmineManagerFactory.createConnectionManagerWithExtraTrust(caTrustStore);

            HttpClient client = RedmineManagerFactory.getNewHttpClient(url, connectionManager);

            return RedmineManagerFactory.createWithApiKey(url, apiAccessKey, client);

        } catch (Exception e) {

            System.out.println("Could not connect to Redmine");

            throw new IOException(e.getMessage());

        }

    }



For another example, see IntegrationTestHelper class:



    Optional builtInExtension = getExtensionKeystore();

    if (builtInExtension.isPresent()) {

        return RedmineManagerFactory.createConnectionManagerWithExtraTrust(

                Collections.singletonList(builtInExtension.get()));

    }



## Using a custom (e.g. self-signed) SSL certificate with Client Certificate Authentication

Supposing you have: 

* clientKeyStore: a KeyStore object that has your Client Certificate and Private Key loaded 

* caTrustStore: a Collection\ object that has the custom CAs to use

* password: A string representing clientKeyStore's password



Then the following function will return a RedmineManager object that uses those KeyStores to

connect to Redmine:



    public RedmineManager connectToRedmine(String apiAccessKey, String url) throws IOException {

        try {

            ClientConnectionManaget connectionManager = 

                    RedmineManagerFactory.createConnectionManagerWithClientCertificate(

                    clientKeyStore, password, caTrustStore);  

            HttpClient client = RedmineManagerFactory.getNewHttpClient(url, connectionManager);

            return RedmineManagerFactory.createWithApiKey(url, apiAccessKey, client);

        } catch (Exception e) {

            System.out.println("Could not connect to Redmine");

            throw new IOException(e.getMessage());

        } 

    }



For another example, see IntegrationTestHelper class:



    Optional builtInExtension = getExtensionKeystore();

    Optional builtInClient = getClientKeystore();

    if (builtInExtension.isPresent() && builtInClient.isPresent()) {

        return RedmineManagerFactory.createConnectionManagerWithClientCertificate(builtInClient.get(), 

                "keystore-password", Collections.singletonList(builtInExtension.get()));

    }
