升级到Android Studio 2.0后，在Gradle构build过程中发生大量错误

最近，我将Android Studio从1.5版升级到2.0版，但是从那以后我发现错误和警告的数量有所增加。 大部分错误都没有意义。 有人可以帮忙：

Answer 1

您可以通过删除Android Studio 1.5创build的.idea文件夹并将该项目导入到Android Studio 2.0中作为Gradle项目来摆脱无意义的警告和错误。 它会自动重新创build.idea文件夹。

Answer 2

将-keepattributes EnclosingMethod添加到proguard规则可以抑制这些错误和警告。

为我工作就像一个魅力。

更新：添加-keepattributes EnclosingMethod到proguard规则实际上改变了这些类是如何混淆的。 这保留了可选的属性，这些属性通常是在没有这样的问题的情况下执行代码所必需的。

Answer 3

在我的项目中集成SimpleXML retrofit2转换器后，我收到了几乎相同的消息。 我必须排除一些已经与Android捆绑在一起的库，才能正确构build它。

像这样：

 compile ("com.squareup.retrofit2:converter-simplexml:2.0.2") { exclude group: 'xpp3', module: 'xpp3' exclude group: 'stax', module: 'stax-api' exclude group: 'stax', module: 'stax'} 

Answer 4

上次更新到Android Studio 2.2testing版后，我通过在应用程序build.gradle中更新“buildToolsVersion”以最后可能的版本（从24到24.0.1）解决了问题。

Answer 5

你有没有尝试清理项目和重build？ 在build.gradle文件中你有什么版本的Gradle？

 buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.0.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } 

Answer 6

构build通用集合将生成所需的JAR …

我的build.gradle看起来像这样， commons-collections排除， build.gradle一个更新的版本替代（仍然需要从源代码构build，就像消息告诉人们这样做）：

 dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') // compile 'commons-collections:commons-collections:3.2.2' // compile 'org.apache.commons:commons-collections4:4.1' compile ('org.apache.velocity:velocity:1.7') { exclude group: 'commons-collections', module: 'commons-collections' } } 

Answer 7

答案应该在这里NewRelic导致构build错误
