Gradle：java.io.IOException：管道正在关闭

Question

在我的 CI 机器（Windows 10）上，我运行 Gradle 测试。基本上在机器上，在测试任务之前执行 git pull 和 java 编译。

这个任务...

测试 --tests my.package.SomeTestClass

因此异常而失败...

我正在使用 Gradle 包装器 5.4.1。我的 gradle.properties 看起来像：

org.gradle.daemon=false
org.gradle.jvmargs=-Xmx2g

几个月前，当我启用 Gradle 守护程序时，我遇到了同样的问题。

我正在监控我的 CI 机器，我可以看到此时机器有大约 750MB 的可用内存，这比所需的 512MB 多（参见例外）。不确定这是否相关，但节点正在运行 Quickbuild 代理。

这个错误究竟意味着什么，我该如何摆脱它？
