在aapt PNG文件处理过程中，Android.apk构建与Gradle一起失败

我看到人们在编译Android时已经遇到了Gradle的问题，但似乎没有人会遇到在Gradle运行aapt命令处理PNG文件时不时出现的特定问题

我的环境：

• Linux Ubuntu 2009-04
• JVM v1.7.0_65
• gradlev1.11
• Android构建工具v19.1.0
• 针对Android API级别19的编译

有时，大约每3次构建，Gradle.apk生成会在处理应在final.apk中提供的PNG文件时失败

失败的命令如下所示：

/opt/android-sdk/build-tools/19.1.0/aapt s -i /home/opt/buildAgent/work/bb4757955823a092/myProject/src/main/res/drawable-sw600dp-hdpi/ic_under_18.png -o /home/opt/buildAgent/work/bb4757955823a092/myProject/build/res/all/myFlavor/release/drawable-sw600dp-hdpi/ic_under_18.png

这会导致Gradle构建失败，出现以下异常（Gradle构建是由Ant脚本启动的，但直接运行它会导致相同的问题），这会导致错误代码：

一旦问题发生，如果我运行失败的命令，即

/opt/android-sdk/build-tools/19.1.0/aapt s -i /home/opt/buildAgent/work/bb4757955823a092/myProject/src/main/res/drawable-sw600dp-hdpi/ic_under_18.png -o /home/opt/buildAgent/work/bb4757955823a092/myProject/build/res/all/myFlavor/release/drawable-sw600dp-hdpi/ic_under_18.png

我没能让它失败。Android构建工具v19.0.3也会出现此问题。我需要指出的是，没有其他构建在同一时间运行，因为我首先怀疑问题是由于并发访问造成的（根据我的说法，这不太可能是根本原因）

我有点失望，因为同一个构建具有完全相同的条件（Gradle构建在开始时使用“清理”任务运行），有时成功，有时失败

请问，有没有人（泽维尔·杜克罗切特？）有什么线索或想法？请告诉我我是否不够清楚，或者重要信息是否丢失

谢谢你的时间和帮助。问候

最终执行以下梯度：

/opt/gradle-1.11/bin/gradle --stacktrace clean myRelease

以下是我的gradle.build文件的摘录，该文件相当重，我无法将其公开：

apply plugin: 'android'

buildscript
{
  repositories
  {
    mavenCentral()
    jcenter()
  }

  dependencies
  {
    classpath 'com.android.tools.build:gradle:0.9.+'
    classpath 'org.gradle.api.plugins:gradle-nexus-plugin:0.7'
  }
}

android
{
  compileSdkVersion 19
  buildToolsVersion '19.1.0'

  defaultConfig
  {
    minSdkVersion 14
    targetSdkVersion 19
  }
}

---

我希望这有助于理解这个奇怪的问题。我真的很想知道问题是否不是直接来自aapt…

在从Ant调用Gradle生成之前，您是否尝试执行一个干净的任务？如果您可以提供build.Gradle文件内容，请。当你可以使用Gradle时，为什么你还在使用Ant？

@Joseph：我添加了一些Gradle脚本的摘录。
