启动生成apache solr时发生java错误。如何修复？

Question

我分叉了这个apache solr，当我尝试按照自述文件中的指示进行构建时，我得到以下错误：

尝试在java版本11上安装时

[root@192 solr]# ./gradlew assemble
Exception in thread "main" java.lang.IllegalArgumentException: error: release version 11 not supported

\nSomething went wrong. Make sure you're using Java 11 or later.

然后我决定将版本更改为1.8.0，收到以下信息：

[root@192 solr]# ./gradlew assemble
Unrecognized option: --source
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
\nSomething went wrong. Make sure you're using Java 11 or later.

有没有人遇到过同样的问题，如果你成功地解决了，那么如何解决
