现在工作正常，没有问题，但是当我尝试添加以下依赖项时：

<dependency>
    <groupId>com.google.firebase</groupId>
    <artifactId>firebase-admin</artifactId>
    <version>6.8.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.google.auto.value/auto-value -->
<dependency>
    <groupId>com.google.auto.value</groupId>
    <artifactId>auto-value</artifactId>
    <version>1.4.1</version>
    <scope>provided</scope>
</dependency>

执行了命令mvn clean package，然后构建失败并出现以下错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:2.2:shade (default) on project friendr-core: Error creating shaded jar: invalid LOC header (bad signature) -> [Help 1]

请帮助我在现有的pom.xml文件中添加这些依赖项。

Answer 1

似乎firebase-admin或auto-value（或两者）已损坏。至少有两种方法可以解决此问题

更改版本

两个软件包都有较新的版本

<dependency>
    <groupId>com.google.firebase</groupId>
    <artifactId>firebase-admin</artifactId>
    <version>6.8.1</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.google.auto.value/auto-value -->
<dependency>
    <groupId>com.google.auto.value</groupId>
    <artifactId>auto-value</artifactId>
    <version>1.6.5</version>
    <scope>provided</scope>
</dependency>

这将使maven下载这些库的新版本，这应该没问题，除非您确实有理由要使用在问题中指定的版本。尝试再次运行mvn clean package

删除本地缓存的库

Maven存储（缓存）依赖项副本。默认情况下，它们存储在

Windows：C:\Users\{your-username}\.m2\repository
Linux / Mac：~/.m2/repository

通过删除以下文件夹~/.m2/repository/com/google/firebase/firebase-admin/6.8.0和~/.m2/repository/com/google/auto/value/auto-value/1.4.1（或Windows相似）删除两个库的缓存版本

然后尝试再次运行mvn clean package

由于Firebase SDK依赖关系导致构建失败
