A set of Java annotations which can be used in JVM-based languages. They serve as an additional documentation and can be interpreted by IDEs and static analysis tools to improve code analysis.

The annotations are published on Maven Central and JCenter. To add a dependency using gradle write the following in the build.gradle file:

dependencies {
    compileOnly 'org.jetbrains:annotations:18.0.0'
}

To add a dependency using Maven write the following in pom.xml:

<dependency>
  <groupId>org.jetbrains</groupId>
  <artifactId>annotations</artifactId>
  <version>18.0.0</version>
</dependency>
