compiling java files when one depends on a jar

Xplugin=$KOTLIN_HOME/lib/kotlin-annotation-processing.jar Here is how you can pass arbitrary options to javac: Kapt uses Java compiler to run annotation processors. Note that incremental annotation processing requires incremental compilation to be enabled as well. To disable incremental annotation processing, add this line to your gradle.properties file: Currently, annotation processing can be incremental only if all annotation processors being used are incremental. Kapt supports incremental annotation processing that is enabled by default. Turn off the discovery of annotation processors in the compile classpath by adding this line to your gradle.properties file: However, compile avoidance can't be used for annotation processors discovered in the compile classpath since any changes in them require running the annotation processing tasks.Īdd the annotation processor dependencies to the kapt* configurations manually as described above. For example, the only changes are in method bodies.

The changes in dependencies are ABI compatible. The project's source files are unchanged. Particularly, annotation processing is skipped when: With compile avoidance enabled, Gradle can skip annotation processing when rebuilding a project. To improve the times of incremental builds with kapt, it can use the Gradle compile avoidance. # specify annotation processors' full names to disable caching for them To enable this feature, use the following properties in your gradle.properties file: We would appreciate your feedback on it in YouTrack.Ĭaching for annotation processors' classloaders helps kapt perform faster if you run many Gradle tasks consecutively.

It may be dropped or changed at any time. Caching for annotation processors' classloadersĬaching for annotation processors' classloaders in kapt is Experimental. When you use the custom JDK home feature in the Kotlin Gradle plugin, kapt task workers use only process isolation mode. To use the Gradle worker API for parallel execution of kapt tasks, add this line to your gradle.properties file: However, running kapt with Gradle worker API enabled can result in increased memory consumption due to parallel execution. Using the worker API lets Gradle run independent annotation processing tasks from a single project in parallel, which in some cases significantly decreases the execution time. To improve the speed of builds that use kapt, you can enable the Gradle worker API for kapt tasks.
