问题
My pom.xml
is running an Ant task to deploy a file using FTP. However, this deployment must be only done if the -Dftp=true
argument is given in the Maven command (i.e. mvn clean install -Dftp=true
). Thus, I wrote the following code:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.2</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks if="ftp">
<echo message="Deploying files through FTP..."/>
...
</tasks>
</configuration>
</execution>
</executions>
Using this pom.xml
, the Ant task is not executed if I do not define the -Dftp
property in my Maven command. However, if I give any kind of value for this property, for example -Dftp=false
, the Ant task is run, which is not correct.
How configure the AntRun task to be run only if a given property has a given value?
ps: I know I can use a profile
that is only active when ftp
is equal to true
. This solution works, but for some reason, I want to have my Antrun plugin build
block.
<profiles>
<profile>
<id>deployment</id>
<activation>
<activeByDefault>false</activeByDefault>
<property>
<name>ftp</name>
<value>true</value>
</property>
</activation>
<build>
<plugins>
<plugin>
... (define the Ant task here)

There is an if task in Ant-contrib that you could use:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.3</version>
<executions>
<execution>
<id>ftp</id>
<phase>package</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<taskdef resource="net/sf/antcontrib/antcontrib.properties"
classpathref="maven.plugin.classpath" />
<if>
<equals arg1="${ftp}" arg2="true" />
<then>
<echo message="The value of property ftp is true" />
</then>
<else>
<echo message="The value of property ftp is not true" />
</else>
</if>
</tasks>
</configuration>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>ant-contrib</groupId>
<artifactId>ant-contrib</artifactId>
<version>20020829</version>
</dependency>
</dependencies>
</plugin>
You don't need the <else>
, this was just for demo purpose.

In case you don't like IF syntax in Ant-contrib you can use antelopetasks.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<inherited>false</inherited>
<configuration>
<target>
<taskdef name="if" classname="ise.antelope.tasks.IfTask"/>
<if name="maven.ant.target">
<ant target="${maven.ant.target}"/>
<else>
<fail message="Please specify a target to execute in 'maven.ant.target' property" />
</else>
</if>
</target>
</configuration>
<dependencies>
<!-- http://antelope.tigris.org/nonav/docs/manual/bk03.html -->
<dependency>
<groupId>org.tigris.antelope</groupId>
<artifactId>antelopetasks</artifactId>
<version>3.2.10</version>
</dependency>
</dependencies>
</plugin>

With maven-antrun-plugin:1.8 You can specify attributes in the <target/> configuration to execute or not Ant tasks depending some conditions as described in Maven antrun plugin documentation
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.8</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<target if="ftp">
<echo message="To run, just call mvn package -Dftp=true"/>
</target>
</configuration>
</execution>
</executions>
</plugin>
As you requested, but using <target/> instead of deprecated <tasks/>
