我想通过Git从源代码构建Eclipse JDT Core。Naïvely，我克隆了git://git.eclipse.org/gitroot/jdt/eclipse.jdt.core.git，并试图从Git master分支运行mvn validate(最基本的Maven阶段)，但这失败了，错误如下。
我是一个Debian Linux用户，安装了Maven 3.0.5和JDK 1.7。
我有兴趣破解类ASTParser，它可以解析Java代码。我知道构建Eclipse项目很困难，但是我在网上找不到构建这个项目的明确的"配方"页面。
在我的Eclipse Juno安装(更新到最新)中，这是我的JDT Core JAR文件:org.eclipse.jdt.core_3.8.3.v20130121-145325.jar。我试图建立在这个标签(v20130121-145325)，但我得到一个类似的错误。
Git分支master上mvn validate的日志:
