Invoke ant target from another target with <groovy> - ant

Question

I have the following script:
<target name="query">
<taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy" classpathref="libraries"/>
<groovy>
import groovy.sql.Sql
def sql = Sql.newInstance("jdbc:oracle:thin:#mydomain.com:1521:alias", "test", "test", "oracle.jdbc.pool.OracleDataSource")
List productNames = sql.rows("SELECT name from PRODUCT")
//println(productNames.count)
productNames.each {
println it["name"]
// HOW TO INVOKE ANT TARGET TASK HERE? TARGET TASK WILL USE it["name"] VALUE
}
properties."productNames" = productNames
</groovy>
</target>
<target name="result" depends="query">
<echo message="Row count: ${productNames}"/>
</target>
I would like to invoke another ant target from "query" target. Especially inside of productNames loop, like put in comments above.
Do you have any idea how to do it?

Answer 1

There are some binding objects in the <groovy> scope (see the documentation for more details), more specifically there is ant object which is an instance of AntBuilder (see the api here), with this object you can invoke getProject() method to get an instance of org.apache.tools.ant.Project and with this Project you can use executeTarget(java.lang.String targetName) method to execute a different target passing its name. All together looks like: ant.getProject().executeTarget("yourTargetName") and in your code:
<target name="query">
<taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy" classpathref="libraries"/>
<groovy>
import groovy.sql.Sql
def sql = Sql.newInstance("jdbc:oracle:thin:#mydomain.com:1521:alias", "test", "test", "oracle.jdbc.pool.OracleDataSource")
List productNames = sql.rows("SELECT name from PRODUCT")
//println(productNames.count)
productNames.each {
println it["name"]
ant.getProject().executeTarget("yourTargetName")
}
properties."productNames" = productNames
</groovy>
</target>
EDIT BASED ON COMMENT:
Passing parameters to the ant call it's not possible through org.apache.tools.ant.Project methods, however there is another way to do so, using ant or antcall tasks through AntBuilder, using antcall however it's not supported inside <groovy> if you try to use it you will get this error message:
antcall not supported within AntBuilder, consider using 'ant.project.executeTarget('targetName')' instead
So you must use ant task. For example if you have the follow ant target with a parameter in your build.xml:
<target name="targetTest">
<echo message="param1=${param1}"/>
</target>
You can call it from <groovy> passing a parameter like this:
<target name="targetSample">
<taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy" classpathref="groovyLibs"/>
<groovy>
ant.ant(antfile:'build.xml'){ // you antfile name
target(name:'targetTest') // your targetName
property(name:'param1',value:'theParamValue') // your params name and values
}
<groovy>
</target>
If you execute this <groovy> target example with ant targetSampe you will get:
targetTest:
[echo] param1=theParamValue
BUILD SUCCESSFUL

Hope this helps,
