Question

鉴于我有Dependency groupId和artifactId，如何从pom.xml文件中提取此依赖项的版本？

示例：如果我使用artifactId和groupId进行查询，我希望能够提取下面的依赖项版本。

        <dependency>
            <groupId>commons-pool</groupId>
            <artifactId>commons-pool</artifactId>
            <version>1.6</version>
        </dependency>

我想将版本分配给全局环境变量，即DEP_VERSION = 1.6

Answer 1

它是一个xml。平凡的，你可以解析文件。

Answer 2

您可以使用Maven Dependency Plugin：

mvn dependency:tree -Dincludes=com.google.guava:guava

它将输出如下内容：
