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

This question already has answers here: Making Maven run all tests, even when some fail (5 answers) Closed 3 years ago.

Actuality when i run tests they fails but i need to run them to get some .class files which are very important 开发者_JAVA百科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...

Please refer to surefire:test for details, but the most useful properties are:

-Dmaven.test.failure.ignore=true (or -DtestFailureIgnore=true) - will ignore any failures occurred during test execution

-Dmaven.test.error.ignore=true ( deprecated ) - will ignore any errors occurred during test execution

-DskipTests - would compile the test classes but skip test execution entirely

-Dmaven.test.skip=true - would not even compile the tests

I believe that in your case where you want to compile test classes but not fail the build due to any tests errors and still create the jar.

You should use the first option to ignore any test failures which you can still review once the build has finished.

mvn -Dmaven.test.skip=true package skips the surefire test mojo.

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>

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

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

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

---

Use -DskipTests=true instead of -Dmaven.test.skip=true in order to skip tests but compile them.

Using -Dmaven.test.failure.ignore=true will also work but is not very nice.

---

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

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