如何阅读“链接文件资源失败”错误消息？

Question

我定期且自发地获得这些信息，而我永远无法刻意解决它们。这是构建日志：

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:processDebugResources'.
    at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:103)

Caused by: com.android.builder.internal.aapt.v2.Aapt2Exception: Android resource linking failed
Output:  X:\Documents\All\Creative\Programming\Projects\Theo\app\src\main\res\layout\activity_login.xml:74: error: resource integer/login (aka org.andrewedgar.theo:integer/login) not found.
error: failed linking file resources.

我看到了对我的一个活动布局（activity_login）的引用，但是几周内我都没有触及该文件或其对应的类。甚至第74行也没有任何内容：

恢复到我承诺的版本仍然无法解决问题。使缓存无效/重新启动，并且清理/重建无效。有没有针对此类错误的典型解决方案？

Answer 1

error: resource integer/login (aka org.andrewedgar.theo:integer/login) not found。看起来您曾经拥有此资源，但现在您没有它。

您需要删除@integer/login并执行clean和build。如果没有帮助，请执行以下操作：

  

文件->使缓存无效/重新启动

或者您也可以将登录资源添加到values文件夹中的xml文件中。

Answer 2

您所引用的属性"@integer/login"很可能在您的项目中不存在。 实际上，该错误表明以下内容：

error: resource integer/login (aka org.andrewedgar.theo:integer/login) not found.

通常，这种类型的错误与xml有关，并指出您正在使用无法识别的属性。

Answer 3

  找不到

资源 integer/login。

如何添加名称为integer的类型为login的丢失资源？

例如res/values/numerical.xml都一样：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <integer name="login">1</integer>
</resources>
