Based on async-profiler 2.8.3

This is not a fork of async-profiler. This is a work derived from async-profiler but tailored very specifically for Datadog needs. If you need a full-fledged Java profiler head back to async-profiler

!TODO!

1. This project contains Java code and is built by gradle, as such, you need to install a JDK in order to build it. Run brew install openjdk to install it on MacOS. If building and testing on Apple Silicon (M1+), be sure to install an aarch64 OpenJDK distribution, otherwise the architecture used for compilation and the JVM based test suite will not match, which means the tests will not be able to load the dynamic library at runtime.
2. The build requires make, which is included in XCode, but can also be installed by running brew install make
3. The build supports googletest for unit testing. To install it, run brew install googletest or sudo apt install libgtest-dev or apk add gtest-dev depending on your platform.

Once prerequisites have been installed simple as ./gradlew assembleAll. The resulting artifact is located in ddprof-lib/build/libs/ddprof-<version>.jar

For dd-trace-java you just need to set the java.profiler.jar project property. Eg. you can run the gradle build like this - ./gradlew clean -Pjava.profiler.jar=file://<path-to-artifact.jar> :dd-java-agent:shadowJar- which will result in a customdd-java-agent.jar` build containing your test version of Java profiler.
