Maven antrun: pass maven properties to ant

Question

I am trying to pass maven properties (defined through profiles) to a antrun execution:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.7</version>
    <dependencies>
        <!-- ... these are ok -->
    </dependencies>
    <executions>
        <execution>
            <configuration>
                <target>
                    <property name="ant_destDir" value="${destDir}" />
                    <property name="ant_serverDeploy" value="${serverDeploy}" />
                    <property name="ant_deployDir" value="${deployDir}" />
                    <property name="ant_userDeploy" value="${userDeploy}" />
                    <property name="ant_passwordDeploy" value="${passwordDeploy}" />
                    <!-- correct task definitions for sshexec and scp -->
                    <sshexec host="${serverDeploy}" username="${userDeploy}" 
                            password="${passwordDeploy}" trust="yes" 
                            command="some command" />
                    <scp remoteTodir="${userDeploy}@${serverDeploy}:${destDir}" 
                            password="${passwordDeploy}" trust="yes" sftp="true">
                        <fileset dir="${deployDir}" includes="*.jar" />
                    </scp>
                    <sshexec host="${serverDeploy}" username="${userDeploy}" 
                            password="${passwordDeploy}" trust="yes" 
                            command="some command" />
                </target>
            </configuration>
            <phase>install</phase>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
</plugin>

The properties are defined in profiles to allow for deployment in different servers (I know it's not the best possible approach, but this is the way things are done here), like this:

<profile>
    <id>aprofile</id>
    <properties>
        <property name="serverDeploy" value="somevalue" />
        <property name="userDeploy" value="someuser" />
        <property name="passwordDeploy" value="somepassword" /> 
        <!-- and so on -->
    </properties>
</profile>

My problem is that I can't get maven properties to work in ant plugin; I tried to add a <echoproperties> task in ant to see which properties I have and there is no trace of maven properties. Is it possible to use maven defined properties or should I use another approach? Any suggestion is welcome.

Edit: I modified the script as per first answer, it still doesn't work

Answer 1

You can pass the properties by defining new Ant properties (using the property tag in your target within the configuration). So for example:

<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-module</artifactId>
    <name>test-module</name>
    <version>SNAPSHOT</version>

    <properties>
        <my.custom.property>false</my.custom.property>
    </properties>

    <profiles>
        <profile>
            <id>customProfile</id>
            <properties>
                <my.custom.property>true</my.custom.property>
            </properties>
        </profile>
    </profiles>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-antrun-plugin</artifactId>
                <version>1.7</version>
                <executions>
                    <execution>
                        <id>compile</id>
                        <phase>compile</phase>
                        <configuration>
                            <target>
                                <property name="antProperty" value="${my.custom.property}"/>
                                <echo message="Custom Ant Property is: ${antProperty}"/>
                                <echoproperties />
                            </target>
                        </configuration>
                        <goals>
                            <goal>run</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>

When I execute mvn compile on this pom the output is:

main:
[echo] Custom Ant Property is: false
[echoproperties] #Ant properties
[echoproperties] #Thu Aug 08 17:17:30 CEST 2013
[echoproperties] ant.project.name=maven-antrun-
[echoproperties] ant.version=Apache Ant(TM) version 1.8.2 compiled on December 20 2010
[echoproperties] antProperty=false

and when the command is mvn -PcustomProfile compile then the output is:

main:
[echo] Custom Ant Property is: true
[echoproperties] #Ant properties
[echoproperties] #Thu Aug 08 17:18:30 CEST 2013
[echoproperties] ant.project.name=maven-antrun-
[echoproperties] ant.version=Apache Ant(TM) version 1.8.2 compiled on December 20 2010
[echoproperties] antProperty=true

This works using maven 3.0.5.

Most properties are automatically passed along to ant, at least if you're running an inlined ant script. Some of the properties get renamed. I suggest running "mvn -X" and the antrun plugin prints a list of all the variable mappings into ant (things like basedir becomes project.basedir, etc.)
