maven 多個父依賴中jar包沖突解決辦法

在jenkins插件開發的過程中，maven父項目基本是plugin

 

 

 在紅箭頭標記的地方，這兩個地方是指定了父項目中一些依賴的版本，但是這兩個依賴版本中，各自依賴的一些jar包很可能會有沖突，這時候，使用exclude 也無法使用。compile時會有如下錯誤：

[INFO] ------------------------------------------------------------------------

按照我之前一篇排除jar包沖突辦法，找到類似：Require upper bound dependencies error for org.eclipse.jetty:jetty-io:9.2.12.v20150709 paths to dependency are:   這句話定位到所沖突的jar包。

這里以jetty-io  jar包為例。

 

 

可以看到 這個jar包在項目里有兩個版本號，是在  jenkins-test-harness   里，這個就是我們引入的plugin 父模塊中的，此時exclude也不好使，那么辦法是使用   dependencyManagement  這個標簽來鎖定一些jar包的版本，部分配置如下：

<!-- 鎖定版本，ant 1.9.2 -->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.apache.ant</groupId>
                <artifactId>ant</artifactId>
                <version>1.9.2</version>
            </dependency>
            <dependency>
                <groupId>org.eclipse.jetty</groupId>
                <artifactId>jetty-util</artifactId>
                <version>9.2.15.v20160210</version>
            </dependency>
            <dependency>
                <groupId>org.eclipse.jetty</groupId>
                <artifactId>jetty-io</artifactId>
                <version>9.2.12.v20150709</version>
            </dependency>
            <dependency>
                <groupId>org.codehaus.plexus</groupId>
                <artifactId>plexus-utils</artifactId>
                <version>2.1</version>
            </dependency>
        </dependencies>
    </dependencyManagement>

然后再次compile

, 

發現還有　jetty-io  的錯誤提示，不要慌，仔細看，錯誤提示不一樣了，

+-org.eclipse.jetty:jetty-io:9.2.12.v20150709 (managed) <-- org.eclipse.jetty:jetty-io:9.2.15.v20160210
這里提示，jetty-io  版本使用 9.2.15.v20160210  版本

    <!-- 鎖定版本，ant 1.9.2 -->
    <dependencyManagement>
        <dependencies>
            <dependency>

                <version>2.1</version>
            </dependency>
        </dependencies>
    </dependencyManagement>

再次compile就不會有  jetty-io   jar包沖突了
