Android support-v4的无效LOC标头Maven编译错误

Question

当maven构建我的pom.xml文件时,我收到编译失败错误.

编译错误是:

error reading C:\Users\amrit\.m2\repository\com\google\android\support-v4\r6\support-v4-r6.jar; invalid LOC header (bad signature).

有谁知道如何解决这个问题？以下是我的pom.xml档案:

我无法解决这个问题.任何形式的帮助将不胜感激.

该错误意味着本地缓存.jar已损坏.请删除C:\Users\amrit.m2\repository\com\google\android\support-v4\r6\support-v4-r6.jar并允许Maven重新下载该文件.

如果错误仍然发生,则Maven正在下载的源存储库.jar很糟糕.考虑切换Maven存储库或更改为库的不同版本 - r7(如果可以),例如:

<dependency>
    <groupId>com.google.android</groupId>
    <artifactId>support-v4</artifactId>
    <version>r7</version>
</dependency>

或者.jar从Maven存储库手动下载,例如http://mvnrepository.com/artifact/com.google.android/support-v4/r6

注意: Google不负责将这些库添加到Maven存储库,这就是为什么a)它们没有及时更新b)为什么(有时)它们已损坏 - 请参阅使用maven的Android支持库设置
