# profiles

* Using a profile to run a build.
* Can run each profile using mvn clean verify -P
* Can activate multiple profiles mvn clean verify -P ,
* USe of maven-help-plugin, to display active profile at compile time
  * ```
    <build>
          <plugins>
              <!-- display active profile in compile phase -->
              <plugin>
                  <groupId>org.apache.maven.plugins</groupId>
                  <artifactId>maven-help-plugin</artifactId>
                  <version>3.1.0</version>
                  <executions>
                      <execution>
                          <id>show-profiles</id>
                          <phase>compile</phase>
                          <goals>
                              <goal>active-profiles</goal>
                          </goals>
                      </execution>
                  </executions>
              </plugin>

          </plugins>
      </build>
    ```
  *   use profiles to set properties

      * ```
        ```

      no-tests true \`\`\`
* we can configure many elements such as dependencies, plugins, resources, finalName.
*   Activating profile by default

    * ```
      ```

    integration-tests true \`\`\` - Dont need to use -P to run the profile - If we use the -P, this will use the profile instead of the default one
* Activate automatically, based on env variable -D
  * ```
    <profile>
      <id>active-on-property-environment</id>
      <activation>
          <property>
              <name>environment</name>
          </property>
      </activation>
    </profile>
    ```
  * mvn package -Denvironment
  * Or by the absence
    * ```
      <profile>
          <id>not-active-on-property-environment</id>
          <activation>
              <property>
                  <name>!environment</name>
              </property>
          </activation>
      </profile>
      ```
    * So calling mvn package -Denvironment will not run this profile
