我正在尝试将我们过时的 Ant 构建转换为 Gradle。该项目包含大约 50 个 Java 子项目和 10 个 Scala 子项目。Java 项目仅包含 Java,Scala 项目仅包含 Scala。每个项目都是由 Java 然后 Scala 构建的,这大大减慢了我们的构建速度。
我想在根 build.gradle 文件中放置尽可能多的通用逻辑,如下所示:
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 the sbt compiler (not scalac ant task)
tasks.withType(ScalaCompile) {
scalaCompileOptions.useAnt = false
}
task showCompileClasspath << {
sourceSets.main.compileClasspath.each { println it }
}
test {
systemProperty "user.dir", projectDir
}
}
当我运行我的构建时,我得到以下输出,请注意:esb-server:compileJava
并:esb-server:compileScala
包含相同的警告,因此类被构建了两次。另请注意,每个其他项目都包含一个compileJava
和compileScala

我知道apply plugin
我的根目录顶部的两行build.gradle
导致了这种行为。但是,如果我只对每个子项目应用正确的插件,我就无法将通用配置重构到我的 rootbuild.gradle
中。另一种方法是对所有东西都使用 Scala 插件,但这是最好的方法吗?
我可以使用 Java 插件编译 Java 项目并使用 Scala 插件编译 Scala 项目,并且仍然将我所有项目的通用构建配置重构到根目录build.gradle
吗?在 Gradle 中支持多种语言的最佳方式是什么?
