Answer 1

您可以通过将--host_jvm_args=--add-opens=java.base/java.nio=ALL-UNNAMED和--host_jvm_args=--add-opens=java.base/java.lang=ALL-UNNAMED启动标志传递给Bazel来解决此问题。

可能值得为Arch包提交一个bug，因为它是一个不传递这些标志的发行版bug。

Answer 2

在深入研究之后，Archlinux打包了jdk-openjdk，它是Java17，而bazel是基于JDK-11构建的，所以在“默认”情况下它会失败。

另一种修复方法是更改"JAVA_HOME“的用法：

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk

bazel clean
bazel build //:ProjectRunner

注意:您也可以尝试使用助手脚本ref：https://wiki.archlinux.org/title/java#Switching_between_JVM将环境切换到JDK11
