How to build a jar using maven, ignoring test results ?

Question

Actuality when i run tests they fails but i need to run them to get some .class files which are very important for my jar.

By default when test results fails , the jar is not build , could i add a setting in pom.xml which ignore that, so I can build the jar ignoring results from tests ?

I read something about "Maven Surefire Plugin" but I don't know how to use it...

Answer 1

<properties>
<maven.test.skip>true</maven.test.skip>
<maven.test.failure.ignore>true</maven.test.failure.ignore>
</properties>

http://jira.codehaus.org/browse/SUREFIRE-319

Or from command line

http://maven.apache.org/maven-1.x/plugins/test/properties.html

maven.test.error.ignore Yes Set this to true to ignore errors during testing. Its use is NOT RECOMMENDED, but quite convenient on occasion maven.test.failure.ignore Yes Set this to true to ignore a failure during testing. Its use is NOT RECOMMENDED, but quite convenient on occasion

Answer 2

mvn -Dmaven.test.skip=true package skips the testing phase

to ignore test failures and keep maven from stopping you can add this to the section of the pom.xml:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
      <testFailureIgnore>true</testFailureIgnore>
    </configuration>
  </plugin>

Answer 3

Use the maven option -Dmaven.test.skip=true

E.g. mvn package -Dmaven.test.skip=true

Answer 4

The solution is:

mvn -fn clean install

execute mvn --help for advanced options

Here's the excerpt for -fn

 -fn,--fail-never         NEVER fail the build, regardless
                          of project result
