Answer 1

您可以通过传递--host_jvm_args=--add-opens=java.base/java.nio=ALL-UNNAMED和--host_jvm_args=--add-opens=java.base/java.lang=ALL-UNNAMED启动标志给 Bazel。

可能值得为 Arch 包提交一个错误，因为它是一个不传递这些标志的分发错误。

Answer 2

经过一番挖掘，Archlinux 软件包jdk-openjdk是 Java 17，而 bazel 是针对 JDK-11 构建的，因此“默认”它会失败。

修复它的另一种方法是更改​​“JAVA_HOME”使用：

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

bazel clean
bazel build //:ProjectRunner

注意：您也可以尝试使用帮助脚本archlinux-java ref 将您的 env 切换到 JDK 11： https : //wiki.archlinux.org/title/java#Switching_between_JVM
