升级到 Android Studio 2.0 后 Gradle 构建过程中出现大量错误

Question

最近，我将 Android Studio 从版本 1.5 升级到了 2.0，但从那以后我发现错误和警告的数量有所增加。大多数错误没有意义。有人可以帮忙吗：

Answer 1

您可以通过删除 Android Studio 1.5 创建的 .idea 文件夹并将项目作为 gradle 项目导入 Android Studio 2.0 来消除无意义的警告和错误。它将自动重新创建.idea 文件夹。

Answer 2

将-keepattributes EnclosingMethod 添加到proguard 规则会抑制这些错误和警告。

像魅力一样为我工作。

更新： 将-keepattributes EnclosingMethod 添加到proguard 规则实际上会改变类的混淆方式。这保留了执行代码通常必需的可选属性没有此类问题。

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使其正确构建。

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

在上次更新到 Android Studio 2.2 测试版后，我通过在 app build.gradle 中将“buildToolsVersion”更新到最后可能的版本（从 24 到 24.0.1）解决了问题。

Answer 5

您是否尝试过清除项目并重建？ 在 build.gradle 文件中，你的 gradle 版本是什么？

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

构建Common Collections 将生成所需的 JAR ...

我的build.gradle 看起来像这样，排除了commons-collections 并替换为更新的版本（仍然需要从源代码构建，就像消息告诉人们要做的那样）：

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 causing build errors

添加 proguard-rules.pro

-keep class         org.apache.commons.beanutils.** { *; }
-keep interface     org.apache.commons.beanutils.** { *; }
-keep enum          org.apache.commons.beanutils.** { *; }
