Setting Maven params in Jenkins

Question

I am experimenting the Jenkins, and am looking for a way to allow Jenkins to set parameters for different project builds. Normally all these attributes are stored in the set

There are some options for you. Here's what I'm using:

Create profiles in your build.

<profile>
    <activation>
        <file>
            <exists>findbugs-exclude.xml</exists>
        </file>
    </activation>
    <build>
        <plugins>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>findbugs-maven-plugin</artifactId>
                <configuration>
                    <excludeFilterFile>findbugs-exclude.xml</excludeFilterFile>
                </configuration>
            </plugin>
        </plugins>
    </build>
</profile>
<profile>
    <id>package</id>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <executions>
                    <execution>
                        <id>copy-dependencies</id>
                        <phase>package</phase>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>${project.build.directory}/lib</outputDirectory>
                            <overWriteReleases>false</overWriteReleases>
                            <overWriteSnapshots>false</overWriteSnapshots>
                            <overWriteIfNewer>true</overWriteIfNewer>
                            <includeScope>runtime</includeScope>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</profile>

The you can define in jenkins clean install -P package - for package task or clean install for normal build

Put parameters directly to pom from command line:

Maven call:

mvn clean install -Dparameter.one=ONE -Dparameter.two=TWO

POM:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.test</groupId>
    <artifactId>test</artifactId>
    <version>1.0.0</version>
    <name>test</name>
    <properties>
        <testng.version>6.4</testng.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.testng</groupId>
            <artifactId>testng</artifactId>
            <version>${testng.version}</version>
            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

If you run it normally testng version 6.4 will be used. But if you run it like: mvn clean install -Dtestng.version=6.3.1 testng version 6.3.1 will be used.

See

You can parametrize default part of pom (setting default values directly and overriding it by execution properties)

Finally you can use environment variables Parameterized Build or Parameterized Trigger Plugin

Change in last example version:

<dependency>
    <groupId>org.testng</groupId>
    <artifactId>testng</artifactId>
    <version>${env.testngVersion}</version>
    <scope>test</scope>
</dependency>

In bash you can call:

export testngVersion=6.0
mvn clean install

Or in jenkins by setting testngVersion=6.0 in This build is parameterized section
