具體地說，它會嘗試遞歸查找pom.properties文件，但是當它調用file.isDirectly （）它有一個問題，確定它的目錄和NPE被拋出。我已經驗證，事實上，目錄存在的權限是正確的......

public static File recurseToPomProperties(File file) { 
    if(file.isDirectory()) { 
     for (java.io.File child : file.listFiles()) { 
      if (child.isDirectory()) { 
       File returnedFile = recurseToPomProperties(child); 
       if (returnedFile != null) { 
        return returnedFile; 
       } 
      } else if (child.getName().endsWith("pom.properties")) { 
       return child; 
      } 
     } 
    } 
    return null; 
}

對我來說，這個錯誤與Drools的相關項目在Windows默認驅動器上運行並非如說明這裏：https://issues.jboss.org/browse/DROOLS-354

我的tomcat服務器在驅動器「D：」上運行，而我的工作空間位於「C：」上。當我把它全部移到「C：」時，完美地工作。也許它有幫助。
