遇到errors occurred during the build这个问题很久了，没有找到好的方法，一直都是用debug下的apk包再签名，这样就不能对apk包进行混淆和加密等操作了，诸多不便！
所以还是要解决这个问题，百度是不行了，于是进到项目根目录下进入.detadata文件夹下，查看eclipse的日志文件.log。查看后得知，如下所示：
!ENTRY com.android.ide.eclipse.adt 4 0 2015-05-04 09:58:57.962 !MESSAGE Export Wizard Error !STACK 1 org.eclipse.core.internal.resources.ResourceException: Errors occurred during the build. at

问题出在：
Contains: Errors running builder ‘Integrated External Tool Builder‘ on project ‘UmengLibs‘.
如此，选择‘UmengLibs’项目，右键单击；选择“Properties”选项，在弹出菜单中选择“Builders”项；删除带红叉的builders，然后就可以导出项目了。
