app:processDebugResources'. > java.lang.IllegalArgumentException(no error message)

今天在导入一个老的工程，原来是用的eclipse写的，现在要导入studio，在编译时报错，在eclipse中却不报错，真的很奇怪。错误信息如下，

Error:Execution failed for task ':app:processDebugResources'.java.lang.IllegalArgumentException (no error message)

(no error message)当时就蒙蔽了，没有错误信息，在eclipse上没有报错，怎么一到studio上就报错了呢，一般编译报错那肯定是clean然后在rebuild尝试了无数次都没用，那只有仔细看日志找错误了。message中只能看到是资源文件出了问题，但是具体不知道是哪个资源文件除了问题。再来看看gradle console里的日志

一行一行看了半天还是没找到有用的信息，就在网上找了半天，国内找到一个说是应用的包名含有数字，例如com.5xxxxx.xxxx.5xxsj这样的会导致这样的问题，但是这个项目包名是正确的，所以排除这个原因。
国内找不到就到翻墙去国外找，大多数人都说肯定是某个资源资源错了导致编译不通过，但是项目这么多文件怎么找啊，这里可以告诉大家一个好方法，就是二分法，将所有的资源 文件单独提出来不要代码，先删掉上面的一办，如果不报错那么有问题的资源文件就在上半部分，多试几次缩小范围，最终确定了是一个资源文件中一个view的id有问题，

  <Button            android:id="@+id/ open_control"            android:layout_width="120dp"            android:layout_height="wrap_content"            android:layout_marginTop="20dp"            android:text="Control" />

就是id那有个空格导致的，但是studio并没有报错，只有早编译时报错，提示no message，看不到任何有用的信息，找了半天终于找到了这个bug也是无语，既然不报错，也不给提示。

总结：
如果报这个错，目前我知道两个原因，一个就是包名含数字，就是manifests中的包名不能包含数字；另一个就是我遇到了，控件id中包含空格。这个真的不好找啊。网上还有人说资源文件放错位置也有可能导致这个错误，反正只要报app:processDebugResources java.lang.IllegalArgumentException就是资源文件有问题，找不到具体哪个文件的话就按照我的方法找吧，总会找到的。
