Backend: DSN is required (sentry) / reqwest4j on Alpine

[DarkCat09]

Official Instance

• The bug is reproducible on the official hosted instance, or is API-related.

Describe the bug

I'm trying to run Piped backend without Docker.
I'm using OpenJDK 17 on Alpine Linux, ./gradlew shadowJar executes without errors.
But piped.jar does not start, Sentry throws IllegalArgumentException even if I uncomment SENTRY_DSN in config.properties and/or set it to empty string.
I've checked that config is successfully read by Constants.class including SENTRY_DSN option.

To Reproduce

1. git clone https://github.com/TeamPiped/Piped-Backend src && cd src
2. ./gradlew shadowJar
3. cp build/libs/piped-1.0-all.jar ../piped.jar && cp config.properties .. && cd ..
4. java -jar ./piped.jar

Expected behavior

Piped server should start without errors.

Logs/Errors

Exception in thread "main" java.lang.IllegalArgumentException: DSN is required. Use empty string to disable SDK.

Okay, after modifying Main.java (I've replaced Constants.SENTRY_DSN with "") and installing package gcompat, it starts with another error, afaik related to Alpine's musl libraries:

Can I build libreqwest by myself, or maybe completely disable Sentry that loads this library?

[DarkCat09]

Oh, I got it, libreqwest is loaded by Piped, not Sentry. So I need to modify and compile rocks.kavin.reqwest4j.ReqwestUtils, then use my version of the library in Piped build.

[FireMasterK]

You can build libreqwest from https://github.com/TeamPiped/reqwest4j, maybe you could build it as a git dependency.

[DarkCat09]

@FireMasterK, thank you for the answer.
I've cloned the repository, built the rust library in reqwest-jni subdirectory, and run ./gradlew shadowJar (also tried build, jar tasks). There is no native libraries in the output JAR, only Java code.
Piped doesn't start with my JAR.
How to build it correctly?

[DarkCat09]

I built reqwest-jni with cargo build --target x86_64-unknown-linux-musl --release and added the output .so library to reqwest4j-1.0.4-all.jar/META-INF/natives/linux/x86_64/libreqwest.so using 7z archiver.
Then compiled Piped with custom libreqwest4j JAR, and... it works!
