Maven Release Plugin - Multi-module project skipping modules

Question

I am using maven-release-plugin on a multi-module project with the following layout:

ROOT/
  + parent
  + module1
  + module2

In the parent's pom, the child modules configured using modules element. Each one of the projects are configured to use the plugin with basic configuration and a tag base for each. I have the following problems:

• When I run mvn release:prepare on parent, after the line that says Checking for snapshot dependencies ..., I receive no prompt to enter the versions. If I press Enter for the number of questions it requires answer, it continues. Why do not I receive prompts on the screen? (The same thing happens if run with -DdryRun=true)

• After running mvn release:prepare (with or without -DdryRun=true), the release:prepare is SKIPPED for the child modules.

I am using the basic configuration on the plugin's guide. I'd be thankful for any ideas or clues of what's wrong.

Answer 1

Regarding the lack of prompts, are you running mvn through a pipe? This happened to me when I was using a script to do colour highlighting of Maven's log output, because Maven doesn't output a newline after the prompt.

By the way, you may be able to use mvn's -B option to run in batch mode; maven-release-plugin will use the default values instead of prompting.
