gradle - 未找到名称为 'java' 的 SoftwareComponentInternal

Question

应用模块build.gradle

apply plugin: 'com.android.library'
apply from: rootProject.file('deploy-bintray.gradle.kts')
android {...}

部署-bintray.gradle.kts 这是我的 bintray/maven 出版物脚本。
我在生成 .jar 文件时遇到问题:

val sourcesJar by tasks.registering(Jar::class) {
    archiveClassifier.set("sources")
    from(project.the<SourceSetContainer>()["main"].allSource)
}

publications {
        create<MavenPublication>(bintrayRepo) {
            groupId = publishedGroupId
            artifactId = artifact
            version = libraryVersion

            from(components["java"])
            artifact(sourcesJar.get())
            artifact(dokkaJar.get())
            ...
            }
        }
    }

它失败了:

SoftwareComponentInternal with name 'java' not found.

或者，如果我评论 from(components["java"])它失败了:

SourceSet with name 'main' not found.

如果我添加 java 插件:

The 'java' plugin has been applied, but it is not compatible with theAndroid plugins.

所以我被困在这里。我该如何解决这个问题？

Answer 1

我终于找到了解决办法!
我做错了一些事情，首先，dokkaJar 和 sourceJar 任务都必须在主 build.gradle而不是在deploy-bintray.gradle.kts .移动它们使其工作并修复:

SourceSet with name 'main' not found.

其次我们不能使用 from(components["java"])因为这是一个 Android 库，所以我用 artifact("$buildDir/outputs/aar/${artifactId}-release.aar") 替换了该行.
最后但同样重要的是，如 here (step 7) 所述:

"Also, the POM file generated does not include the dependency chain soit must be explicitly added..."

我不得不添加这个:

pom {
...
    withXml {
       val dependenciesNode = asNode().appendNode("dependencies")
       configurations.getByName("implementation") {
         dependencies.forEach {
            val dependencyNode = dependenciesNode.appendNode("dependency")
            dependencyNode.appendNode("groupId", it.group)
            dependencyNode.appendNode("artifactId", it.name)
            dependencyNode.appendNode("version", it.version)
         }
       }     
    }       
}
