I have a java application that is in git repo RepoA and has a scm configuration set up for this repo for maven-release plugin etc. I want to fetch one file from another RepoB (it is fine to checkout the whole repo also because there is only 1 file there) and use it as a part of build step. How to do it with maven-scm plugin if scm section is already set up for RepoA?
Thanks.
You can use a separate maven profile for this task.
Here's profile part from pom.xml, assuming that you want to fetch file foo/bar.txt from github repo github-user/some-repo:
<profile>
<id>checkout-foo-bar</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-scm-plugin</artifactId>
<version>1.11.2</version>
<configuration>
<connectionUrl>scm:git:[email protected]:github-user/some-repo</connectionUrl>
<includes>foo/bar.txt</includes>
</configuration>
</plugin>
</plugins>
</build>
</profile>
Then run mvn scm:checkout -P checkout-foo-bar
Plugin first fetches all the files from repo and then removes ones that you don't need. This takes extra time, especially if the repo is huge.
I didn't find a way to setup output directory other than default target/checkout. But hopefully this working example can be a good starting point to solve a problem.
