Copy dependencies to project's local repository
java, maven, maven-dependency-plugin
Solution
Use the `maven-dependency-plugin:copy-dependencies` goal instead. If `useRepositoryLayout` and `copyPom` properties are set to true, it will create such a local repository.
The goal can be called from the command line as:
mvn org.apache.maven.plugins:maven-dependency-plugin:3.0.2:copy-dependencies -Dmdep.useRepositoryLayout=true -Dmdep.copyPom=true -DoutputDirectory=./repository-exported
Problem
`maven-dependency-plugin:copy` copies a single jar. I need to copy the jar and the pom to the appropriately named path in accordance with repository structure. Use case: My project has a local repository, where I keep non-public dependencies. The dependencies are projects that I build on my machine and which get installed to the local machine's repository. After I copy the artifacts to the project's local repository, I can build the project on any machine which doesn't have the sources of the other projects. Using a project local repository is easy. You just need a folder with a particular directory structure and include this in the POM: ``` <repositories> <repository> <id>in-project</id> <name>In Project Repo</name> <url>file://${project.basedir}/libs</url> </repository> </repositories> ``` However, copying stuff into the local repo is an extra step I'd like to avoid. `maven-dependency-plugin:copy` almost does what I need. ``` <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.8</version> <executions> <execution> <id>copy-private-dependencies</id> <phase>prepare-package</phase> <goals> <goal>copy</goal> </goals> <configuration> <artifactItems> <artifactItem> <groupId>...</groupId> <artifactId>...</artifactId> </artifactItem> </artifactItems> <outputDirectory>${project.basedir}/libs</outputDirectory> <overWriteReleases>true</overWriteReleases> <overWriteSnapshots>true</overWriteSnapshots> <overWriteIfNewer>true</overWriteIfNewer> </configuration> </execution> </executions> </plugins> </build> ``` But it just copies the dependency's jar, without the pom and without the necessary directory structure.
