How to use something similar to fileset and pathconvert of ant in Gradle

I am trying to convert an Ant project to Gradle. One target is executing a Java Main class. And list of java files are passed into the Main class as argument.

Ant Code :

<target name="someThing">
        <fileset dir="src/main/java" id="input.files">
            <include name="**/api/SomeApi.java"/>
            <include name="**/temporaryuserdata/api/Some2API.java"/>
        </fileset>
        <pathconvert pathsep=" " property="javaFiles" refid="input.files"/>
        <java classname="com.some.tool.MainClass" classpathref="buildtools.classpath" fork="true" failonerror="true">
            <arg value="${javaFiles}"/>
        </java>
    </target>

I converted it to gradle using the ant support in gradle in following way: Gradle Code: 

task someThing(type: JavaExec) {
    classpath = sourceSets.main.runtimeClasspath
    main = 'com.some.tool.MainClass'
    ant.fileset(dir : '', id: 'input.files'){
        include(name : "**/api/SomeApi.java")
        include(name : "**/api/Some2API.java")
    }
    ant.pathconvert(pathsep : " ", refid: "input.files", property: "javaFiles")
    args = [ant.properties["javaFiles"]]
}

It works as expected. However, I don't want to use the ant things in gradle.

Can somebody help me get the same output of fileset and pathconvert using the proper gradle and groovy tools?

You could do this

FileTree files = fileTree('src/main/java').matching {
    include '**/api/SomeApi.java' 
    include '**/api/SomeApi2.java' 
} 
args = [files.asPath]

But really you should use the JavaCompile task for this rather than JavaExec

Gradle has great api to work with files:

https://docs.gradle.org/current/userguide/working_with_files.html

For example you can use fileTree:

FileTree tree = fileTree(dir: 'src', includes: ['**/api/SomeApi.java', '**/api/Some2API.java'])
