Maven Checkstyle插件和番石榴/谷歌收藏依赖冲突

Question

在我们的多模块maven（3）项目中，我们正在使用maven checkstyle插件。 由于我们已经将番石榴的依赖关系转移到了父pom，因此我们再也无法成功执行checkstyle：checkstyle目标，因为它失败，并带有以下异常：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-checkstyle-
plugin:2.10:checkstyle (default-cli) on project init: Execution default-cli of goal 
org.apache.maven.plugins:maven-checkstyle-plugin:2.10:checkstyle failed: An API 
incompatibility was encountered while executing org.apache.maven.plugins:maven-
checkstyle-plugin:2.10:checkstyle: java.lang.NoSuchMethodError: 
com.google.common.collect.ImmutableSortedSet.of([Ljava/lang/Comparable;)Lcom/google
/common/collect/ImmutableSortedSet;
[ERROR] -----------------------------------------------------
[ERROR] realm =    plugin>org.apache.maven.plugins:maven-checkstyle-plugin:2.10

原因可能是maven checkstyle插件依赖于checkstyle框架，而该框架取决于google-collections框架（当前包括在google guava框架中），即checkstyle调用的方法不属于google集合中的一部分。番石榴了。

这是正在使用的父pom的摘录：

我认为在Maven项目中使用Maven Checkstyle插件以及使用guava框架都是非常普遍的。 所以我真的很想知道我们在这里做错了什么;）

非常感谢@AndrewLogvinov。 他在对该问题的评论中提出了可行的解决方案。 只需要将google-collections依赖项添加到maven-checkstyle-plugin的依赖项中：

<dependency>
    <groupId>com.google.collections</groupId>
    <artifactId>google-collections</artifactId>
    <version>1.0</version>
</dependency>
