gradle - Gradle将发布从Gradle 4.x迁移到5.x？

Question

如何将以下发布从Gradle 4迁移到5？

publishing {
    publications {
        foo(MavenPublication) {
            artifactId "foo"
            artifact jar

            pom.withXml {
                def dependenciesNode = asNode().appendNode('dependencies')

                def dependencyNode = dependenciesNode.appendNode('dependency')
                dependencyNode.appendNode('groupId', 'mygroup')
                dependencyNode.appendNode('artifactId', 'bar')
                dependencyNode.appendNode('version', '1.0')

            }
        }
    }
}

这适用于gradle 4.5.1。但是对于gradle 5.4.1，错误:

Execution failed for task ':publishFooPublicationToMavenLocal'.
> Failed to publish publication 'foo' to repository 'mavenLocal'
   > Invalid publication 'foo': artifactId is not a valid Maven identifier ([A-Za-z0-9_\-.]+).

使用gradle 4.8+，您必须将publishing{}块包含在project.afterEvaluate中

project.afterEvaluate {
    publishing {
      publications {
        foo(MavenPublication) {
          artifactId "foo"
          artifact jar

          pom.withXml {
            def dependenciesNode = asNode().appendNode('dependencies')

            def dependencyNode = dependenciesNode.appendNode('dependency')
            dependencyNode.appendNode('groupId', 'mygroup')
            dependencyNode.appendNode('artifactId', 'bar')
            dependencyNode.appendNode('version', '1.0')

         }
      }

    }
}

您可以找到 official doc here:

Prior to Gradle 4.8, the publishing {} block was implicitly treated as if all the logic inside it was executed after the project was evaluated. This was confusing, because it was the only block that behaved that way. As part of the stabilization effort in Gradle 4.8, we are deprecating this behavior and asking all users to migrate their build.
