eclipse導入svn目錄中的android項目預編譯失敗的問題

最近搭建android開發環境遇到一個很是狗血的問題，在eclipse中導入svn中項目時，預編譯報錯，查看workspace 內的日誌文件，錯誤內容以下：

java.lang.NullPointerException
	at com.android.ide.eclipse.adt.internal.build.SourceProcessor.scanFolderForSourceFiles(SourceProcessor.java:374)
	at com.android.ide.eclipse.adt.internal.build.SourceProcessor.scanFolderForSourceFiles(SourceProcessor.java:380)

 因此致使不可以自動生成資源代碼。

以前懷疑是64位JDK或者eclipse的問題換成32位後結果仍是報錯，最終將svn客戶端從1.6 升級到1.7後解決了這個問題。 估計是1.6的svn與ADT不兼容致使的。。。
