[AC-6528] Failed to run dexer : Server returned HTTP response code: 403

After 2 months i try to build my app like before, but i have the following error : Failed to run dexer: [ERROR] : [ERROR] : Exception in thread "main" java.lang.RuntimeException: java.io.IOException: Server returned HTTP response code: 403 for URL: http://services.gradle.org/distributions/gradle-4.6-all.zip I tried to access the URL mentionned and the URL don't work (tried on 2 computers). So i guess i have to manually download the missing zip in another website but i dont know where i have to put it, i will search... *EDIT : *Problem was temporary, URL is accessible again and problem is solved. For information you have to go in Titanium SDK 7.4.2.GA folder/android/templates/gradle/gradle-wrapper/gradle-wrapper.properties to edit the URL used for download, of course its possible to find the path to where to put the zip file from there.
