Maven: Build only one module out of multi-module project

Question

I have a multi-module Maven project wherein I just want to release an update module rather than the entire project. This is due to some specific requirements, wherein a release of entire project is uncalled for - only a subset of the library needs the fixes and thus the release.

However, when I run a mvn release:prepare I get the following error Non-resolvable parent POM - I have setup the parent POM relationship in the module project with relativePath tag but that does not seem to work.

Is it possible to release only a module rather than releasing the entire project.

Thanks in advance.

EDIT

Parent pom

<groupId>com.domain</groupId> <artifactId>project-parent</artifactId> <version>0.5.1-SNAPSHOT</version>  <packaging>pom</packaging>  <modules>     <module>library1</module>     <module>library2</module>     <module>library3</module> </modules> 

The module POMs are as under:

<parent>     <groupId>com.domain></groupId>     <artifactId>project-parent</artifactId>     <version>0.5.1-SNAPSHOT</version> </parent>  <artifactId>library1</artifactId> 

Now I just want to release the new version of library1 and not others

Answer 1

mvn -pl .,library1 clean install 

The "." will build your parent pom.xml and "library1" is the module name you gave it.

If you don't want to build the parent pom.xml, you can also do:

mvn -pl library1 clean install 

or in your case, maybe:

mvn -pl library1 deploy 

I used "deploy" because "release" is not a Maven build lifecycle phase.
