gradle: how to invoke ant.javac with multiple includes defined at runtime? - gradle

Question

for some reasons I don't use the java plugin for gradle, but I invoke ant.javacdynamically. How can I build a dynamic javac include() based on a list ?
for example:
def srcToCompile=["**/File1.java","**/File2.java","**/FileN.java"];
(...)
ant.javac(
destdir: tmpDir,
srcdir: srcDir
includeantruntime:false,
failonerror: true,
fork: true,
classpath : classpath1,
debug: true
) {
include(name: srcToCompile) //<< DOESN'T WORK, I also tested srcToCompile.join(":")
}
thanks.
EDIT: by 'doesn't work', I mean ant.javac doesn't interpret a List or a colon-separated-string: no source is found and nothing is compiled. ant.javac expects something like
include(name:"**/File1.java")
include(name:"**/File2.java")
include(name:"**/FileN.java")
but I want to generate this list of include when gradle is invoked.

If you look an ant javac docs you'll see that includes and include both accept a string but you are trying to pass a collection
Eg:
<javac destdir="${build}"
classpath="xyz.jar"
debug="on">
<src path="${src}"/>
<src path="${src2}"/>
<include name="mypackage/p1/**"/>
<include name="mypackage/p2/**"/>
<exclude name="mypackage/p1/testpackage/**"/>
</javac>
and
<javac srcdir="${src}"
destdir="${build}"
includes="mypackage/p1/**,mypackage/p2/**"
excludes="mypackage/p1/testpackage/**"
classpath="xyz.jar"
debug="on"/>
In Gradle this would be
ant.javac(includes: srcToCompile.join(','), ...)
or
ant.javac(
...
) {
srcToCompile.each {
include(name: it)
}
}
