I am following the installation guide but when I try to run the script on obfuscated-app.apk, I am getting the following error.

Development Environment:
java version "1.8.0_241"
Gradle Version: 6.1.1

I have tested it on 3 different machines with the same dev environment.
1: Local ubuntu machine
2: Virtual Santoku machine
3: AWS Server ubuntu machine

This is my first time using simplify, kindly guide me if I am missing something. Thanks

P.S: I cloned it recursively as mentioned in build guide.

Actually it took 16 minutes to build jar on virtual machine, about 3 minutes to build jar on local/host machine and 39 seconds on AWS server. You are seeing 1 second in screenshot because I re run the command with --stacktrace flag. That's why it took just 1 second.

  1. Yes I cloned recursively.
  2. About 60K
  3. I have tried ./gradlew clean build command and this time build failed.

Here is the html report.

I am not sure why this build failed this time because I already used fresh ubuntu server on AWS. I mean nothing was installed before. It got build successfully but this time got failed.

@CalebFenton I have changed the branch to v1.2.1 and build it again and that's worked perfectly fine. So its something wrong with new code. :)

@Eightgreen Would you please send the stacktrace? Why it failed?
