Java SDK for [Milvus](https://github.com/milvus-io/milvus). To contribute to this project, please read our [contribution guidelines](https://github.com/milvus-io/milvus/blob/master/CONTRIBUTING.md) first.

## Getting started

### Prerequisites

- Java 8 or higher
- Apache Maven or Gradle

The following table shows compatibilities between Milvus and Java SDK.

| Milvus version | Java SDK version |
|:--------------:|:----------------:|
| 2.0 | 2.0.4 |
| 2.1 | 2.1.0-beta4 |
| 2.2.0 ~ 2.2.8 | 2.2.0 ~ 2.2.5 |

| 2.4.x | 2.4.2 |

### Install Java SDK

You can use **Apache Maven** or **Gradle** add Milvus SDK to your project.

- Apache Maven

```xml

io.milvus
milvus-sdk-java
2.4.2

```

- Gradle/Groovy

```groovy
implementation 'io.milvus:milvus-sdk-java:2.4.2'
```

- Gradle/Kotlin

```kotlin
implementation("io.milvus:milvus-sdk-java:2.4.2")

### Documentation

### Troubleshooting

- If you encounter the following error when running your application:
```
Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
```
This is because SLF4J jar files need to be added into your application's classpath. SLF4J is required by Java SDK for logging purpose.

To fix this issue, you can use **Apache Maven** or **Gradle** to download the required jar files.

- Apache Maven

```xml

org.slf4j
slf4j-api
1.7.30

```

- Gradle/Groovy

```groovy
compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.30'
```
- Gradle/Kotlin

```kotlin
implementation("org.slf4j:slf4j-api:1.7.30")
```
