Maven发布：准备目标

Question

We have the following config in our POM file:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
        <skip>true</skip>
    </configuration>
    <executions>
        <execution>
            <id>surefire-it</id>
            <phase>integration-test</phase>
            <goals>
                <goal>test</goal>
            </goals>
            <configuration>
                <skip>false</skip>
            </configuration>
        </execution>
    </executions>
</plugin>

This ensures that the tests are not executed during test phase. Tests are executed only during integration-test phase.

However, when we prepare for release (release:prepare), maven executes the tests during test phase. This causes our build to fail because our tests can be run only during Integration test phase (we use tomcat-maven plugin to deploy the packaged war before the tests can be executed).

I know that we can skip the tests by passing the parameter (-DskipTests etc.). We do not want to skip any tests, we just want release:prepare to execute just like any other maven goal.

Any suggestion/help is highly appreciated.

Answer 1

Add your integration tests in a separate profile which isn't active by default. Add a triggerring rule or something. Then invoke the builds with the integration tests on a need by need basis. For example, on your CI (Jenkins/Hudson, TeamCity, Bamboo, etc) triggered the profile.

The problem you are currently facing is that you haven't made a separation between the two types of tests and when they should run. You have simply defined the phases you would like them to execute in. This isn't sufficient knowledge of the execution context for Maven to figure out what you would like to do and it invokes them during the release as well.

Answer 2

Try with the more general approach to disable the maven-surefire-plugin completely during test phase.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <executions>
        <execution>
            <id>default-test</id>
            <!-- Disable the default-test by putting it in phase none -->
            <phase>none</phase>
        </execution>
        <execution>
            <!-- Enable the test during integration-test phase -->
            <id>surefire-it</id>
            <phase>integration-test</phase>
            <goals>
                <goal>test</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Edit

This is the output from my dry run of mvn release:prepare with the above configured surefire plugin:

Answer 3

I would try an alternate approach, and try to configure the release plugin to always use -DskipTests as an argument so you don't need to specify it each time:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-release-plugin<artifactId>
    <configuration>
        <arguments>-DskipTests</arguments>
    </configuration>
</plugin>

In theory this should append -DskipTests to the arguments that the prepare and release goals pass to the sub-executions of Maven that they execute.

Answer 4

Use the maven-failsafe-plugin for the integration tests, and keep maven-surefire-plugin for the unit tests.

This will guarantee that the unit tests are completely segregated from the integration tests (and can therefore be turned off separately), and the integration tests are run during the " integration-test and verify phases of the build lifecycle".
