找出依赖发行者

Question

我在我的web项目中使用以下库:

• SLF4J-log4j12-1.6.4.jar
• SLF4J-API-1.6.0.jar
• log4j的-1.2.16.jar
• JCL-过SLF4J-1.6.0.jar

当我组装war时,将额外的commons-logging-1.0.4.jar库复制到WEB-INF/lib.我认为这是因为我的一个库依赖于commons-logging-1.0.4.jar.我想排除commons-logging-1.0.4.jar(由于jcl-over-slf4j-1.6.0.jar已经在这里)使用

<dependency>
    <groupId></groupId>
    <artifactId></artifactId>
    <version></version>
    <exclusions>
           ...
    </exclusions>
</dependency>

为此,我需要找到我的pom中的库取决于commons-logging.

您可以使用mvn dependency:tree命令找到依赖关系树.

从树中,您可以排除工件.

示例输出:

[INFO] |  +- org.seleniumhq.selenium:selenium-htmlunit-driver:jar:2.20.0:test
[INFO] |  |  +- org.seleniumhq.selenium:selenium-api:jar:2.20.0:test
[INFO] |  |  +- net.sourceforge.htmlunit:htmlunit:jar:2.9:test
[INFO] |  |  |  +- xalan:xalan:jar:2.7.1:test
[INFO] |  |  |  |  \- xalan:serializer:jar:2.7.1:test
[INFO] |  |  |  +- commons-collections:commons-collections:jar:3.2.1:test
[INFO] |  |  |  +- commons-lang:commons-lang:jar:2.6:test
[INFO] |  |  |  +- org.apache.httpcomponents:httpmime:jar:4.1.2:test
[INFO] |  |  |  +- commons-codec:commons-codec:jar:1.4:test
[INFO] |  |  |  +- net.sourceforge.htmlunit:htmlunit-core-js:jar:2.9:test
[INFO] |  |  |  +- xerces:xercesImpl:jar:2.9.1:test
[INFO] |  |  |  |  \- xml-apis:xml-apis:jar:1.3.04:test

如果依赖项是可传递的,您可以根据上面的树执行以下操作:

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-htmlunit-driver</artifactId>
    <version>2.20</version>
</dependency>
<dependency>
    <groupId>net.sourceforge.htmlunit</groupId>
    <artifactId>htmlunit</artifactId>
    <version>2.9</version>
    <!-- i dont want u -->
    <exclusions>
        <exclusion>
            <groupId>commons-collections</groupId>
            <artifactId>commons-collections</artifactId>
        </exclusion>
    </exclusions>
</dependency>
