Beanshell

This rule can execute a beanshell script and evaluate the result.

The following parameters are supported by this rule:

• condition - the beanshell statement to evaluate.
• message - an optional message to the user if the rule fails.

Sample Plugin Configuration:

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-enforcer-plugin</artifactId>
        <version>3.6.0</version>
        <executions>
          <execution>
            <id>enforce-beanshell</id>
            <goals>
              <goal>enforce</goal>
            </goals>
            <configuration>
              <rules>
                <evaluateBeanshell>
                  <condition>${project.artifactId} == foo</condition>
                </evaluateBeanshell>
              </rules>
              <fail>true</fail>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

The condition can be a complex script or a simple expression. As long as it results in True, the rule will succeed. This means code can be executed as long as the last line results in true.

  <evaluateBeanshell>
    <condition>for (int i = 0;i!=10;i++){print ("Hello World "+i);};1==1</condition>
  </evaluateBeanshell>
