In Maven, how output the classpath being used?

Question

For my current purposes I have a Maven project which creates a war file, and I want to see what actual classpath it is using when creating the war.

Answer 1

This is a single command solution but does compile the code.

mvn -e -X -Dmaven.test.skip=true clean compile | grep -o -P '\-classpath .*? ' | awk '{print $2}'

• It's based in Philip Helger's previous answer (Thanks by the way)

Shell script example usage

MAVEN_CLASSPATH=$(mvn -e -X -Dmaven.test.skip=true clean compile | grep -o -P '\-classpath .*? ' | awk '{print $2}')

I used a variation of it in a shell script to run a standalone main() (for Hibernate schema generation) this way

#/bin/bash

MAVEN_TEST_CLASSPATH=$(mvn -e -X clean package | grep -o -P '\-classpath .*?test.*? ')

java $MAVEN_TEST_CLASSPATH foo.bar.DBSchemaCreate

File output example

mvn -e -X -Dmaven.test.skip=true clean compile | grep -o -P '\-classpath .*? ' | awk '{print $2}' > maven.classpath
