Question

将数据存储Cassandra驱动程序升级到3.0.1后，我的JUnit测试用例中断了。添加了一项检查，以确保按照Datastax升级页面point 3中所述使用Google guava版本16.0.1。

我明确地在google guava上添加了依赖，最新版本为19.0 ，但这似乎没有帮助，因为测试用例仍然会抛出番石榴版本异常。

为了澄清，只有在执行单元测试时才编译代码。在pom.xml中明确添加19.0时，我无法理解为什么在类路径中旧版本的guava被拾取？我做错了什么？

其他一些帖子如this one描述了Spark和Hadoop的解决方案，但这是一个WAR项目，所以我在maven中运行了一个依赖树，看到19.0取代了推荐的16.0.1。

正如你自己指出的那样，罪魁祸首确实是google-api-client，它取决于一个名为guava-jdk5的非标准番石榴罐，它将Guava 13.0带到你的类路径。

尝试排除它：

<dependency>
    <groupId>com.google.api-client</groupId>
    <artifactId>google-api-client</artifactId>
    <version>1.20.0</version>
    <exclusions>
        <exclusion>
            <groupId>com.google.guava</groupId>
            <artifactId>guava-jdk5</artifactId>
        </exclusion>
    </exclusions>
</dependency>
