报错如下：

代码位置：
/**
* Clean log files if should clean follow strategy
*/
private void cleanLogFilesIfNecessary() {
File logDir = new File(folderPath);
File[] files = logDir.listFiles(); // files 获取得到了空指针
//此处是不是需要加个空指针判断
for (File file : files) {
if (cleanStrategy.shouldClean(file)) {
file.delete();
}
}
}
