基于 Gradle 的子项目在构建期间抛出“无法找到或加载主 class worker.org.gradle.process.internal.worker.GradleWorkerMain”
A Gradle based sub-project throws `Could not find or load main class worker.org.gradle.process.internal.worker.GradleWorkerMain` during the build
我有一个基于 Gradle 的多项目。
问题出在其中一个子项目上。我在那里进行了一些测试，但是里面的所有代码都被注释掉了。当我 运行“构建”甚至“assemble”不应触发测试阶段时，我在测试阶段遇到了这些错误。
这种情况最近才开始发生，我真的无法确定是什么原因导致了这种情况。
