signal-protocol | The Signal cryptographic protocol , for node and browsers | Encryption library

when starting my application with ng serve (now ng serve -- -c deploy, because of testing, every console.log comes from either main.js:1 or polyfills.js:1, independet from which component I call the console.log().

In an other stackoverflow (Angular console logs only from main.js:1 and polyfills.js:1) someone wrote that this appears because angular doesnt build dev and instead buils production.

Here is my angular.json

I want to add the following library to the Gradle build of my project. The library that I want to add is : signal-protocol-java-2.8.1.jar that I have downloaded. How can I add it in the Gradle build, so that I import the classes included in the .jar it in the java classes that I am developing ?

Here is my build.gradle file :

I'm creating a web based chat app using react and decided to implement end to end encryption. So I'm using signal encryption protocol. Now the main library I need to import in order to do end to end encryption is in a file called libsignal-protocol.js (it is available in signals github repo). All functions and variables I need to use is inside a variable called libsignal (example - libsignal.KeyHelper.generateIdentityKeyPair().

Library libsignal-protocol.js doesn't provide javascript modules so I'm importing whole library with a global script declaration.

Recently Added Firebase-Firestore to my android project and while building started getting Duplicate references to classes in the protobuf.
