Is there a way to capture user input in maven and assign it to a maven property?

  1. Is there a way to pause the maven execution flow to provide a command prompt so user can input text.
  2. Then I would like the provided text to be stored in a maven properties.
  3. If the user input could be masked that would be a bonus.

This would be really useful to avoid storing passwords in pom.

Many Thanks

You can catch a user input using maven-antrun-plugin. The following example show how ask current user the new project version.

    <profile>
        <id>change-version</id>
        <build>
            <defaultGoal>validate</defaultGoal>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-antrun-plugin</artifactId>
                    <version>1.7</version>
                    <executions>
                        <execution>
                            <id>catch-new-version</id>
                            <goals>
                                <goal>run</goal>
                            </goals>
                            <phase>validate</phase>
                            <configuration>
                                <target>
                                    <!-- == catch new version in a prompt == -->
                                    <input
                                        message="Please enter the new SNAPSHOT version (current is '${project.version}'): "
                                        addproperty="new-user-version" />
                                </target>
                                <exportAntProperties>true</exportAntProperties>
                            </configuration>
                        </execution>
                    </executions>
                    <dependencies>
                        <dependency>
                            <groupId>org.apache.ant</groupId>

                            <version>1.8.4</version>

                    </dependencies>
                </plugin>
                <plugin>

                    <artifactId>versions-maven-plugin</artifactId>
                    <version>1.3.1</version>
                    <executions>
                        <execution>
                            <id>set-new-version</id>
                            <goals>
                                <goal>set</goal>
                            </goals>
                            <phase>validate</phase>
                            <configuration>
                                <generateBackupPoms>false</generateBackupPoms>
                                <newVersion>${new-user-version}</newVersion>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

You can run this feature by calling :

mvn -N -P change-version

If you add a property in your pom like so:

<properties>
    <db.password></db.password>
</properties>

And use it in your pom somewhere like this:

<someTag>${db.password}</someTag>

Then you can set the property from command line:

$ mvn -Ddb.password="DonaldDuck" install

But it is not interactive like a command prompt.
