Gradle build lintVitalRelease NullPointerException

Question

更新了从3.0 Canary 3到Beta 2的Android Studio，以及从Alpha 5到Beta 2的Gradle插件。调试构建很好，但是当尝试为发布版本类型生成签名的APK时，此错误不断出现。尝试删除.gradle文件夹，.idea文件夹，Invalidate caches＆Restart和gradlew clean。

Answer 1

选项1.推荐。解决问题。

修复问题本身而不是禁用它。

要执行此操作，请转到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。我做了这个，修复了我的错误，现在它编译发布apk。

选项2.禁用检查。

org.gradle.api.tasks.TaskExecutionException：任务'：app：lintVitalRelease'的执行失败。

您应该在build.gradle部分添加checkReleaseBuilds。

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

然后Clean-Rebuild-Run。

Answer 2

How to know what's wrong in your code?

这很简单。在浏览器中打开lint-results-release-fatal.html文件，您将看到代码的确切错误。就我而言，这是一个缺失的翻译。当我在浏览器中打开lint-results-release-fatal.html时，它看起来像这样。

How to open lint-results-release-fatal.html in browser?

转到此路径apps / build / reports / lint-results-release-fatal.html右键单击并选择“在浏览器中打开”选项。如果在项目中找不到它，则可以将透视更改为Project。

如果你仍然困惑。然后按照这3个步骤。

1）将Perspective更改为Project

2）转到apps / build / reports / lint-results-release-fatal.html

3）右键单击并选择“在浏览器中打开”选项

Missing Translation

正如爱德华提到的那样，9/10次是由于缺少翻译。在我的应用程序中，我通过创建备用string.xml文件添加了多语言支持。但忘了用其他语言添加它。我在尝试创建签名APK时遇到此错误。在打开lint-results-release-fatal.html（错误报告）之前，我不知道出了什么问题。所以在Laymen术语中，它就像是通过错误报告。它告诉您根本原因，来源和可能的解决方案。您还可以打开错误报告的XML版本，即lint-results-release-fatal.xml。

错误报告清楚地表明了这一点。
