2、呼叫方式

	@Override
	public boolean mkDir(String jenkinsUser,String jenkinsPass,String serverAddr,String moduleName) {
		// TODO Auto-generated method stub
		
		String warpath="/home/work/.jenkins/jobs"+"/"+moduleName;
	    String command = String.format("if [ ! -d %s ]; then mkdir %s;fi",warpath,warpath);//command格式要正確
	   Boolean res= ExecuteShell.executeRemoteShell(serverAddr,jenkinsUser,jenkinsPass,command);
			
		return res;
	}
