Maven config location.¶
~/.m2/settings.xml.
Generate simple project.¶
$ mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
Debug Maven build.¶
Run build with -X option for verbose logging.
Project directory layout.¶
- http://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html
- Introduction to the Standard Directory Layout.
Get help on Maven plug-in.¶
$ mvn help:describe -DartifactId=maven-war-plugin -DgroupId=org.apache.maven.plugins
$ mvn help:describe -Dcmd=dependency:resolve -Ddetail
$ mvn dependency:tree
$ mvn dependency:list
$ mvn dependency:resolve
$ mvn dependency:resolve-plugins
$ mvn -X ...
Reason for inclusion or omitting dependencies:
$ mvn dependency:tree -Dverbose=true
What actual code processed by Maven (dump Maven config):
$ mvn help:effective-settings
$ mvn help:effective-pom
Force update of dependencies.¶
You can try redownload snapshots by:
$ mvn -U compile
You can fix damaged local ~/.m2 with:
$ mvn dependency:purge-local-repository
In order to perform really clean download:
$ mvn -Dmaven.repo.local=$HOME/.my/other/repository clean install
Find newer library and plugin versions.¶
Check commands from versions-maven-plugin:
$ mvn versions:display-dependency-updates
$ mvn versions:display-plugin-updates
Run Java main from Maven.¶
mvn exec:java -Dexec.mainClass="com.vineetmanohar.module.Main" -Dexec.args="arg0 arg1 arg2"
How to run single unit test?¶
test property substituded to **/${test}.java pattern and override any
include/exclude patterns:
$ mvn test -Dtest=SeriousComponentTest
or mostly same:
$ mvn test-compile surefire:test -Dtest=RunMe
How do I skip the tests during the default lifecycle?¶
$ mvn -DskipTests package
$ mvn -Dmaven.test.skip=true package
Download all external dependencies sources and javadocs.¶
mvn dependency:resolve -Dclassifier=javadoc
mvn dependency:resolve -Dclassifier=sources
Deploy parent pom without building children.¶
$ mvn -N deploy
