android - Gradle 构建 lintVitalRelease NullPointerException

Question

将 Android Studio 从 3.0 Canary 3 更新到 Beta 2，并将 Gradle 插件从 Alpha 5 更新到 Beta 2。调试构建很好，但是当尝试为发布构建类型生成签名 APK 时，此错误不断出现。已尝试删除 .gradle 文件夹、.idea 文件夹、使缓存无效并重新启动和 gradlew clean。

Answer 1

选项 1。推荐。解决问题。

自行解决问题而不是禁用它。

为此，转到 app/build/outputs/lint-results-release-fatal.html 右键单击​​它并选择在浏览器中打开。修复它提供的详细错误。我这样做了，修正了我的错误，现在它编译了发布 apk。

选项 2. 禁用检查。

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:lintVitalRelease'.

您应该在 build.gradle 部分添加 checkReleaseBuilds。

  android {
    lintOptions { 
        checkReleaseBuilds false // Add this
        abortOnError false
    }
}

然后Clean-Rebuild-Run。
