I’m compiling and testing my project with Java 6 even though I’m running latest gradle 6.0.1 on JVM 1.8. I’ve implemented something similar to [this example](https://docs.gradle.org/current/userguide/building_java_projects.html#sec:java_cross_compilation) in the documentation, the only thing is that I’m using ant integration, defining an ant task inside gradle in this way :

` ant.mytest(haltonfailure: false, fork: true, forkmode: 'once', jvm: javaExecutables.java) {`

but since I have to use ant version 1.9.x( because newer ant version 1.10.x are not compatible with java 6), i’m getting now this warning:

WARNING: multiple versions of ant detected in path for junit  
jar:file:/home/ale/.gradle/wrapper/dists/gradle-6.0.1-bin/1lxlpkiy24sb18odw96cp4ojv/gradle-6.0.1/lib/ant-1.10.7.jar!/org/apache/tools/ant/Project.class  
and jar:file:/home/ale/dev/common/lib/unittest/randomizedtesting-runner/ant-1.9.14.jar!/org/apache/tools/ant/Project.class

Is there a way to avoid loading the gradle wrapper dependency version of ant to be part of my ant task runner ? Any other way to avoid the warning ?
