问题
I am currently working on a Gradle custon plugin that should analyse my root project for specific configs in every subproject and then generate some kotlin source code in the build dir. I can't figure out a way to invoke my annotation processor from my gradle plugin which has a custom task for this matter.
Any ideas how to achieve this? Any resource/tutorial/documentation is also highly welcomed.
Thanks in advance and be safe.

After a long time of googling and mostly trying and failing, I finally figured out the solution to my question. Here is my task configuration.
Basically we have to provide the annotation processor's classpath as a project configuration. In my case I added this block to the project's build.gradle
allprojects {
configurations {
myProcessor //pick any name!!!
}
}
and then as a dependency in app build.gradle
dependencies {
myProcessor "PATH_TO_MY_PROCESSOR_JAR" //or maven dependency if it's uploaded to maven central
}
tasks.register(
"myTaskName",
JavaCompile::class.java
) {
compiler ->
with(compiler.options) {
isFork = true
isIncremental = true
}
with(compiler) {
group = shuttle.plugin.ShuttlePlugin.TASK_GROUP
destinationDir = outputDir
classpath = variant.getCompileClasspath(null)
options.annotationProcessorPath = configurations.getByName("myProcessor") //this is the missing piece!!
source = files(projectDir.resolve("src/main/java")).asFileTree
}
}
However, this task will only compile Java classes Only and not kotlin.
Any Idea how to fix this behaviour knowing that my plugin targets only android apps so I don't have direct access to kotlinCompile
gradle default task?
