Java Extension

The following section contains Java-specific extensions to the build server protocol.

Javac Options Request

The build target scalac options request is sent from the client to the server to query for the list of compiler options necessary to compile in a given list of targets.

• method: buildTarget/javacOptions
• params: JavacOptionsParams

export interface JavacOptionsParams {
  targets: BuildTargetIdentifier[];
}

Response:

• result: JavacOptionsResult, defined as follows

export interface JavacOptionsResult {
  items: List[JavacOptionsItem];
}

export interface JavacOptionsItem {
  target: BuildTargetIdentifier;

  /** Additional arguments to the compiler.
   * For example, -deprecation. */
  options: List[String];

  /** The dependency classpath for this target, must be
   * identical to what is passed as arguments to
   * the -classpath flag in the command line interface
   * of javac. */
  classpath: List[Uri];

  /** The output directory for classfiles produced by this target */
  classDirectory: Uri;
}
