关于此还有很多其他相关问题,但我无法在这里进行任何工作。
我在子项目的子集中使用shadowjar来产生一个远的jar。一个子项目产生两个jar(不同的主类)。我正在尝试消除每个子项目中的样板。
我已经尝试了一些方法,但是使用“额外”似乎是到目前为止我尝试过的最经典的方法。但是,它不起作用。
在根中,我有:
subprojects {
afterEvaluate {
val jarFiles by project.extra(listOf<String>())
val mainClasses by project.extra(listOf<String>())
if (jarFiles != null && jarFiles.isNotEmpty()) {
jarFiles.forEachIndexed { idx, jarName ->
tasks.create<com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar>(jarName) {
isZip64 = true
archiveBaseName.set(jarName)
mergeServiceFiles()
manifest {
attributes(mapOf("Main-Class" to mainClasses!![idx]))
}
minimize()
}
tasks.build {
dependsOn(jarName)
}
}
}
}
然后在我尝试过的子项目中:
extra["jarFiles"] = listOf("myproject")
extra["mainClasses"] = listOf("com.foo.Application")
或
val jarFiles by extra(listOf("internal", "external"))
val mainClasses by extra(listOf("com.fooInternalApplication", "com.foo.ExternalApplication"))
但是,它并没有被解雇。我应该关闭还是应该采用完全不同的方法?
答案 0 :(得分:0)
工作解决方案:
subprojects {
// this is needed so that the subproject can )optionally) set it
extra["jars"] = null
afterEvaluate {
// this may have been set by the subproject
val jars = extra["jars"] as Map<String, String>?
jars?.forEach { jar, className ->
tasks.create<com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar>(jar) {
isZip64 = true
archiveBaseName.set(jar)
mergeServiceFiles()
manifest {
attributes(mapOf("Main-Class" to className))
}
exclude("META-INF/INDEX.LIST", "META-INF/*.SF", "META-INF/*.DSA", "META-INF/*.RSA")
minimize()
configurations = listOf(project.configurations.default.get())
// TODO see https://github.com/johnrengelman/shadow/blob/master/src/main/groovy/com/github/jengelman/gradle/plugins/shadow/ShadowJavaPlugin.groovy#L38
// should be able to refer to something along the lines of "conventions"
from("./build/classes/kotlin/main")
}
tasks.build {
dependsOn(jar)
}
}
}
}
然后,在每个需要构建一个或多个jar的子项目中:
extra["jars"] = mapOf(project.name to "com.foo.MainApplication")
或
extra["jars"] = mapOf("internal" to "com.foo.InternalApplication",
"external" to "com.foo.ExternalApplication")
