Android Studio 更新到 1.0 破坏了 MultiDex

Question

您好，有类似的错误，例如重复输入。

失败:构建失败，出现异常。

• 出了什么问题:任务“:eBooks:packageAllDebugClassesForMultiDex”执行失败。

  java.util.zip.ZipException: duplicate entry: android/support/annotation/AttrRes.class

• 尝试:使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

谁能告诉我如何在 jar 文件中找到重复类文件的位置以及如何获得如下输出

com.squareup.okhttp:okhttp:1.6.0| | | +--- com.intellij:annotations:+ -> 12.0

我能够通过包含 aviary-sdk 库在测试项目中重现它。我不需要 multi-dex，也没有研究不同的 SDK 版本，这对我来说似乎有点神秘。

如果你没有 multi-dex，你会得到经典的“multiple dex files define...”错误，这意味着你在你的构建中包含了相同的符号不止一次，这是你不允许的做。

这些问题可能需要一点调查；这就是 gradle dependencies 任务非常方便的地方。如果您进入模块的目录(不是顶级目录)并运行此任务:

../gradlew dependencies

你得到:

如果你仔细观察，你会看到两者:

commons-io:commons-io:2.4

和

org.apache.commons:commons-io:1.3.2

在那里，我没有确认，但我假设是相同类的不同包装，其中包括 org/apache/commons/io/CopyUtils.class。

如果您通过以下方式排除 commons-io:

compile ('com.aviary.android.feather.sdk:aviary-sdk:3.4.3.351') {
    exclude group: 'commons-io'
}

它将构建。我没有试过运行它，所以我不知道运行时是否会丢失符号；如果有，您可以尝试更彻底地处理从依赖项中排除的内容，或者您​​可以重新打包依赖项以修复错误，或者联系其作者。
