推荐答案
更新(仍在Gradle插件3.0.0-beta5中运行，已通过@ TmTron确认)
Update (still working in Gradle plugin 3.0.0-beta5, confirmed by @ TmTron)
classpath 'com.android.tools.build:gradle:3.0.0-beta5'
更新(在Gradle插件3.0.0-beta4中已修复)
Update (fix in Gradle plugin 3.0.0-beta4)
该问题已在Gradle插件3.0.0-beta4中再次修复.预计将包含在下一个AS 3.0 Beta 4中，但可以通过更新顶级build.gradle在当前的AS 3.0 Beta 3中使用:
Issue fixed again in Gradle plugin 3.0.0-beta4. Expected to be included in next AS 3.0 Beta 4, but can be already used in current AS 3.0 Beta 3 by updating top level build.gradle:
classpath 'com.android.tools.build:gradle:3.0.0-beta4'
更新(AS 3.0 Beta 3中的回归)
Update (regression in AS 3.0 Beta 3)
该问题重新出现在beta 3上.Google已经意识到此问题，并已将其重新打开.请参见 https://issuetracker.google.com/issues/64527520
The issue is back on beta 3. Google is already aware of the issue and has reopened it. See https://issuetracker.google.com/issues/64527520
已在将来的Beta 4中修复，有待发布.
Fixed in future beta 4, pending to be released.
感谢@yvolk进行举报，并感谢@ ghui-zhang进行确认.
Thanks @yvolk for reporting it and @ghui-zhang for the confirmation.
最终更新(AS 3.0 Beta 2中的修复程序)
Final Update (fix in AS 3.0 Beta 2)
正如Jordan Bondo在评论中所说，AS 3.0 Beta 2已经发布，其中包含可解决此问题的插件3.0.0-beta2.
As Jordan Bondo says in his comment, AS 3.0 Beta 2 is already released containing the plugin 3.0.0-beta2 that fixes the issue.
因此，解决方案是将插件从3.0.0-beta1升级到至少3.0.0-beta2.
So, the solution is to upgrade the plugin from 3.0.0-beta1 to at least 3.0.0-beta2.
历史
Google在此问题中的优先级为P0(这是TOP优先级)正在处理此问题: https://issuetracker.google.com/issues/64527520
Google is handling this issue with priority P0 (this is TOP priority) in this issue: https://issuetracker.google.com/issues/64527520
同时，@ edgars的解决方法对我来说很有效.谢谢！
In the meantime, @edgars workaround made it for me. Thanks!
Update 2: Fixed, scheduled for next beta "Fix will land in plugin 3.0.0-beta2"
更新:Google员工共享的其他解决方法 :
Update: additional workaround shared by a Googler:
暂时的解决方法是将sdk的最低版本设置为19以下.问题是，尽管平台支持，但Desugar将处理API 19+的try-with-resources，但我们不会打包这些类.
Temporary workaround is to set min sdk version below 19. Issue is that Desugar will process try-with-resources for API 19+, although platform supports it, but we will not package those classes.
更新3 :如果未在Java代码中使用Java 8功能，请将其禁用(这对于Kotlin代码库也很有用).请参阅此评论.
Update 3: if not using Java 8 features in Java code, disable it (this can also be useful for Kotlin codebases). See this comment.
