Maven：如何检查工件是否已安装到本地存储库

Question

我正在编写shell脚本，如果尚未安装它，应该安装它。

是否存在类似mvn install:check artifact-name的内容？

我正在使用：Apache Maven 3.3.9

You can try with dependenct:get in offline mode and specify your repository, the command has the following structure:

mvn dependency:get -Dartifact={groupId}:{artifactId}:{version} -o -DrepoUrl=file://your/repo/path

For example:

mvn dependency:get -Dartifact=junit:junit:4.10 -o -DrepoUrl=file://~/.m2/repository

If it finds the dependency, then you will get:
