How to support multiple projects in multiple languages (Java and Scala) in Gradle? -


i trying convert our antiquated ant build gradle. project contains java 50 sub-projects , 10 scala sub-projects. java projects contain java , scala projects scala. each project getting built java scala slowing down our build considerably.

i want place common logic in root build.gradle file possible looks this:

subprojects {     apply plugin: 'java'     apply plugin: 'scala'      sourcecompatibility=1.7     targetcompatibility=1.7      sourcesets {         main {             scala {                 srcdir 'src'             }             java {                 srcdir 'src'             }         }         test {             scala {                 srcdir 'test'             }             java {                 srcdir 'test'             }         }     }      repositories {         mavencentral()     }      dependencies {         scalatools "org.scala-lang:scala-compiler:2.9.3"         compile "org.scala-lang:scala-library:2.9.3"     }      // use sbt compiler (not scalac ant task)     tasks.withtype(scalacompile) {         scalacompileoptions.useant = false     }      task showcompileclasspath << {        sourcesets.main.compileclasspath.each { println }     }      test {         systemproperty "user.dir", projectdir     } }

when run build following output, notice :esb-server:compilejava , :esb-server:compilescala contain same warnings, classes being built twice. notice every other project contains compilejava , compilescala

i know 2 apply plugin lines @ top of root build.gradle causing behaviour. if apply correct plugin each subproject cannot refactor common configuration root build.gradle. approach use scala plugin everything, best way?

can use java plugin compile java projects , scala plugin compile scala projects, , still refactor common build configuration across projects root build.gradle? best way support multiple languages in gradle?

how this:

configure(subprojects.findall {project -> file('src/main/java').exists() }) { apply plugin: 'java' }

configure(subprojects.findall {project -> file('src/main/scala').exists() }) { apply plugin: 'scala' }

since src directory 'src', other discriminator mechanism inside closures needed
