Gitを使ってソースコードからEclipse JDT Coreをビルドしたいと思っています。 Naïvely、私はgit://git.eclipse.org/gitroot/jdt/eclipse.jdt.core.gitをクローンし、Git masterブランチからmvn validate（最も基本的なMavenフェーズ）を実行しようとしましたが、これは以下のエラーで失敗しました。Git経由でEclipse JDT Coreをソースコードからビルドするには？
私はMaven 3.0.5とJDK 1.7がインストールされているDebian Linuxユーザです。
Javaコードを解析できるクラスASTParserをハックすることに興味があります。私はEclipseプロジェクトの構築が難しいことに気がついていますが、このプロジェクトを構築するために、ネット上のどこでも決定的な "レシピ"ページを見つけることはできません。
私のEclipse Junoインストール（最新版に更新）では、これはJDT Core JARファイルorg.eclipse.jdt.core_3.8.3.v20130121-145325.jarです。このタグ（v20130121-145325）をビルドしようとしましたが、同様のエラーが発生します。 Gitのブランチmaster上mvn validateから
