Gradle 构建失败并出现 NoClassDefFoundError for sun.awt.X11GraphicsEnvironment in :mergeDebugResources

Question

我在尝试构建 microG 时总是收到此错误：

这是在一个甚至没有安装 X 服务器的无头服务器上！发布时也会发生这种情况（mergeReleaseResources 除外）。我尝试使用--info 和--debug 运行，但它没有给我任何有用的东西。我也尝试过使用 Oracle 的 JDK 而不是 OpenJDK 并在机器构建上安装本地 X 服务器，但这也没有改变任何东西。这是一个新克隆的 repo 副本，尽管我不认为该错误是 microG 特有的。

这是我运行./gradlew build --stacktrace的结果：https://gist.github.com/milkey-mouse/cb6b75b5116cf369603dec46e214e914

您可以尝试在gradle.properties 文件中将-Djava.awt.headless=true 添加到您的jvmargs：

org.gradle.jvmargs=-Djava.awt.headless=true

另外请看示例here。

这里是similar question，但与 Gradle 无关。
