问题描述
我在代码中使用 org.eclipse.jdt.core 作为依赖项。我想对 org.eclipse.jdt.core 中的抽象类ASTNode进行小的修改（使构造函数公开）。完成修改后，我要构建它，并在项目中将编译后的 jar 文件用作依赖项 jar 。
因此，我想通过Git从源代码构建Eclipse JDT Core。天真的，我克隆了
git://git.eclipse.org/gitroot/jdt/eclipse.jdt.core.git并按照POST中的建议执行了mvn -P build-individual-bundles package。
几分钟后，我得到以下错误。有任何想法吗？ TIA！
