如何通过 Git 从源代码构建 Eclipse JDT Core？

Question

我想通过 Git 从源代码构建 Eclipse JDT Core。天真地，我克隆了 git://git.eclipse.org/gitroot/jdt/eclipse.jdt.core.git 并尝试从 Git master 分支运行 mvn validate（最基本的 Maven 阶段），但失败并出现以下错误。

我是安装了 Maven 3.0.5 和 JDK 1.7 的 Debian Linux 用户。

我有兴趣破解 ASTParser 类，它可以解析 Java 代码。我意识到构建 Eclipse 项目很困难，但我在网上的任何地方都找不到明确的“食谱”页面来构建这个项目。

在我的 Eclipse Juno 安装中（更新到最新版本），这是我的 JDT Core JAR 文件：org.eclipse.jdt.core_3.8.3.v20130121-145325.jar。我尝试在此标签 (v20130121-145325) 上构建，但我收到了类似的错误。

从 mvn validate 登录 Git 分支 master:
