Find pom in subdirectories and execute mvn clean

Question

What is the command to search all subdirectories containing the pom.xml file and then execute: mvn clean in this subdirectory?

I have workspaces that contain several maven projects and I want to clear all of them

Answer 1

Perhaps something like this should work:

to find. -name "pom.xml" -exec mvn clean -f '{}' \;

Answer 2

in general, you would like to release mvn clean on the parent pom, which will also clean up all children defined as modules.

If you don’t have and don’t need such a parent, you need to use brute force for this, which means something like

 for dir in yourdirectory; do cd $dir if [ -f pom.xml ]; then mvn clean fi done 

Answer 3

I use this script, it calls mvn clean only those projects that need to be cleaned (they have a target directory):

 find . -name "target" -type d \ | sed s/target/pom.xml/ \ | tee /dev/stderr \ | xargs -I {} mvn -q clean -f {} 

The tee part is optional, it just prints the cleaned project.
