How do I get IntelliJ to recognize gradle generated sources dir?

Question

So I have an XJC javaExec that spins like a top but IntelliJ doesn\'t recognize the generated output despite having marked generated-src/java as such. Do I need to

Answer 1

ext {
    // path to IDEA generated sources directory
    ideaGeneratedSourcesDir = "$projectDir/src/main/generated"
}
compileJava {
    //……
    options.annotationProcessorGeneratedSourcesDirectory = file(ideaGeneratedSourcesDir)
    //options.headerOutputDirectory.set(file(ideaGeneratedSourcesDir)) (tested no effect)
    //……
}
// above work for me, and i try all method this question mentioned it's not work! env: idea2019.3, wrapped gradle6.3-all, zh-CN, JDK8, [x] annotation processing is disabled(no effect, in global settings ), no idea plugin([x]plugins {id idea}), [x]sourceSets no need to set(genereated srcDir)

myCodeGenExample:

task vertxCodeGen(type: JavaCompile) {
    group 'build'
    source = sourceSets.main.java
    destinationDir = file(ideaGeneratedSourcesDir)
    classpath = configurations.compileClasspath
    options.annotationProcessorPath = configurations.annotationProcessor
    options.debugOptions.debugLevel = "source,lines,vars"
    options.compilerArgs = [
            "-proc:only",
            "-processor", "io.vertx.codegen.CodeGenProcessor",
            // where the non Java classes / non resources are stored (mandatory) - the processors requires this option to know where to place them
            "-Acodegen.output=$destinationDir.absolutePath",
    ]
}

refresh the gradle, continously exist
