java - 基于 Gradle 的子项目在构建过程中抛出`Could not find or load main class worker.org.gradle.process.internal.worker.GradleWorkerMain`

Question

我有一个基于 Gradle 的多项目。

问题在于其中一个子项目。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。当我运行不应触发测试阶段的“构建”甚至“组装”时，我会在测试阶段遇到这些错误。这种情况最近才开始发生，我无法确定是什么开始导致这种情况。

FAILURE: Build failed with an exception.

我不能真正透露我的构建文件。可以这么说，我在所有子项目的根目录中都使用了 spring gradle 插件和依赖管理插件。子项目构建文件仅包含您的常规依赖项和不同的任务。

根 build.gradle 包含这一行：

wrapper {
    gradleVersion = '6.7.1'
}

我有 JDK 11、Gradle 6.7.1.、IDEA Ultimate 2020.3.3。

我尝试使缓存无效并重新启动，在构建之前清理，删除wrapper文件夹并使用wrapper任务重新生成它，gradlew --stop. 到目前为止没有任何帮助。其他子项目构建良好，这个和 root 没有。

.caches我通过从 Gradle 用户主目录中手动删除文件夹中的所有内容来解决此问题。
