How to specify a git tag when in the configuration of the SCM Maven plugin?
git, maven, maven-3
Solution
The checkout goal doesn't have the `<tag>` element listed as a parameter. It looks like you specify the tag info like this:
<scmVersionType>tag</scmVersionType>
<scmVersion>java-0.6.0</scmVersion>
Problem
As a part of my project's configuration, I'm trying to checkout a specific tag out of a GitHub repository. Currently the plugin configuration is as follows: ``` <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-scm-plugin</artifactId> <executions> <execution><!-- checkout the msgppack-rpc project --> <id>msgpack-rpc-checkout</id> <phase>validate</phase> <goals> <goal>checkout</goal> </goals> <configuration> <goals>checkout</goals> <connectionUrl>scm:git:https://github.com/msgpack/msgpack-rpc.git</connectionUrl> <tag>java-0.6.0</tag> <checkoutDirectory>repoCode/msgpack-rpc</checkoutDirectory> </configuration> </execution> </executions> </plugin> ``` However, the "tag" element seems to be ignored by the Git SCM provider. I've also tried to put the tag directly in the URL, like e.g. so: `scm:git:https://github.com/msgpack/msgpack-rpc.git/refs/tags/java-0.6.0` Unfortunately, this, and other permutations of this format produce errors. I have no other ideas, and I've failed to find an example for this use case anywhere.
