1. Add following script in your module's build.gradle

    task('dumpTasks', dependsOn: 'preBuild') << {
    def p = rootProject.projectDir.parentFile.path
    def f = new File(buildDir, 'outputs/tasks.json')
    def pw = f.newPrintWriter()
    pw.println "{"
    def ts = tasks.findAll{ it.name.contains('Release') }
    def tn = ts.size()
    ts.eachWithIndex { t, ti ->
        pw.println "  \"${t.name}\": {"
        def strings = [:]
        def files = [:]
        def atoms = [:]
        t.properties.each { k, v ->
            if (k == 'path' || k == 'name' || k == 'temporaryDir') return
            if ((v instanceof String)) {
                strings.put(k, v)
            } else if ((v instanceof File)) {
                files.put(k, v)
            } else if ((v instanceof Boolean) || (v instanceof Integer)) {
                atoms.put(k, v)
            }
        }
        strings.each { k, v ->
            pw.println  "    \"$k\": \"$v\","
        }
        files.each { k, File v ->
            String s = v.path
            if (s.startsWith(p)) {
                s = '**' + s.substring(p.length())
            }
            pw.println  "    \"$k\": \"$s\","
        }
        def ai = 0
        def an = atoms.size()
        atoms.each { k, v ->
            ai++
            ai == an ? pw.println("    \"$k\": $v") : pw.println("    \"$k\": $v,")
        }
        tn == ti + 1 ? pw.println('  }') : pw.println('  },')
    }
    pw.println '}'
    pw.flush()
    pw.close()
}

  2. Execute task dumpTasks

    ./gradlew :your_module:dumpTasks

  3. Find the output in your module's build/outputs/tasks.json

    Something like this:
