我正在使用Maven项目，我有两个项目，ProjectA和ProjectB。我的ProjectA是一个maven库，其pom看起来像这样：

ProjectA POM：

</project>

在上面的pom中，PartialKernel带来了spring-core，spring-web等各种Spring Framework依赖项的旧版本。它带来了3.2.8.RELEASE版本，我想使用这两个spring框架的最新版本，即4.1.6.RELEASE。

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.1.6.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>4.1.6.RELEASE</version>
    </dependency>

我需要使用最新版本，因为有些类只有最新版本。所以我在我的pom.xml中添加了这两个库的新版本，就像我在ProjectA中一样。我有一个静态的无效主代码，它将测试ProjectA功能，并且没有任何问题。

现在我有ProjectB，它与上面的pom相同，没有最新版本的spring依赖项。在我的ProjectB pom中，我依赖于ProjectA和相同的代码来测试ProjectA的功能，但每当我在ProjectB中运行相同的类时，我总是得到这个错误。

Exception in thread "main" java.lang.NoClassDefFoundError: org.springframework.util.concurrent.ListenableFutureCallback
Caused by: java.lang.ClassNotFoundException: org.springframework.util.concurrent.ListenableFutureCallback

我正在使用的所有最新的弹簧相关代码都在ProjectA中，其中我已经有了最新版本的spring。我拥有的示例测试代码只是调用ProjectA类来测试它。

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

但是当我在ProjectB中添加最新版本的spring依赖项时，我的测试代码开始正常工作。这就是我不想要的。有什么办法，我的ProjectB开始自动使用我在ProjectA中使用的任何依赖项？如果他们想要更改它，那么他们可以在ProjectB中的代码中覆盖它。

您可以尝试从pom xml中排除依赖项。这是一个例子。

<dependency>
    <groupId>com.texture.partial.core</groupId>
    <artifactId>PartialKernel</artifactId>
    <exclusions>
        <exclusion>  <!-- declare the exclusion here -->
          <groupId>org.springframework</groupId>
          <artifactId>spring-web</artifactId>
        </exclusion>
        <exclusion> 
          <groupId>org.springframework</groupId>
          <artifactId>spring-core</artifactId>
        </exclusion>
  </exclusions> 
</dependency>
