【问题描述】：

最近，我的十次构建中有九次失败，但出现以下异常。我清理并重建项目，但无济于事。我到处搜索并尝试了在其他类似问题上共享的解决方案 - 再次没有帮助。我的 Android Studio 版本是 2.0 Beta 5，Gradle 也是 2.0.0-beta5。这是我收到的例外情况：

谁能提供线索？

【解决方案1】：

升级到 Java 1.8，这个问题应该会消失。我不知道究竟是什么原因导致：java.util.concurrent.ExecutionException 但升级到Java 1.8 总是为我修复它。

java.util.concurrent.ExecutionException： com.android.ide.common.process.ProcessException： org.gradle.process.internal.ExecException：进程'命令 'C:\Program Files\Java\jdk1.7.0_75\bin\java.exe'

【讨论】：

升级了，还是没用。
经过一番研究，您的异常与我过去遇到的异常不同。首先运行 gradle clean 然后尝试以这种方式运行你的任务 gradle --no-daemon --max-workers=1 --rerun-tasks -S -i --recompile-scripts 用你的任务替换。
我将使用该命令完成什么？是要解决问题还是要获得有关错误的更多信息？
两者。您正在关闭许多可能会解决您的问题的 gradles 优化。其次，你告诉它清理并重新运行所有可能清除一些坏缓存的东西。第三然后 --info 会让 gradle 告诉你它采取的每一个动作。它将为您提供大量难以使用的信息，但希望它足以告诉您哪些子任务失败导致“：app：transformClassesWithDexForDebug”任务失败。编辑：-i 与 --info 相同。
谢谢。 --no-daemon 未被识别为命令选项，因此我将其删除。它现在成功建造了 4 次中的 3 次。有一次没有，我得到了这个异常： AGPBI: {"kind":"error","text":"Error convert bytecode to dex:\nCause: java.lang.NullPointerException","sources":[{ }],"original":"UNEXPECTED TOP-LEVEL EXCEPTION:\njava.lang.NullPointerException\n\tat java.io.FileOutputStream.write(FileOutputStream.java:313)\n\tat com.android.dx.command。 dexer.Main.runMultiDex(Main.java:415)\n\tat com.android.dx.command.dexer.Main.run(Main.java:275)\n\tat ........跨度>

【解决方案2】：

我遇到了同样的异常，并且在我清理项目（构建->清理项目）后修复了它。试试看。

【解决方案3】：

这可能是我尝试编译项目时可用 RAM 较少的问题。一旦我释放了内存，它就会自动修复。
