 ## Build
-### Building Local Artifacts
-In order to ease up consuming of the java-profiler library in downstream projects (eg. dd-trace-java) it is possible to quickly build a maven artifact (jar) which can replace the stable dependency to test the changes.
-
-#### Prerequisites
-The local build requires docker and Java 11 to be installed.
-
-#### Build script
-Use `./datadog/scripts/build_locally.sh` to build linux-x64 only maven artifact.
-
-After running this script you should see something like
-```shell
-jaroslav.bachorik@COMP-C02FJ0PSMD6V java-profiler % ./datadog/scripts/build_locally.sh
-=== Building Java Profiler
-==    Version     : 2.6-DD-jb_local_artifact-bc38fb7712459603349d7a36a90c9d02611a450d
-==    Architecture: linux-amd64
-==    With tests  : no
--> Building native library
--> Building maven artifact
--> Build done : Artifacts available |
-*  file:///tmp/ap-tools-2.6-DD-jb_local_artifact-bc38fb7712459603349d7a36a90c9d02611a450d.jar
-```
-
-The artifact version contain the encoded branch name and the HEAD commit hash - which makes it easily identifiable. The actual path of the built artifact depends on your system but you can easily copy-paste it around.
-
-##### Supported arguments
-The build script support the following arguments:
-- `-a <architecture>` 
-  - one of `linux-x64`, `linux-x64-musl` or `linux-arm64` (defaults to `linux-x64`)
-- `-f`
-  - force docker image rebuild
-- `-t`
-  - force test run
-- `-h`
-  - show help
+As simple as `./gradlew build`. The resulting artifact is located in `ddprof-lib/build/libs/ddprof-<version>.jar`
 
 ### Consuming the artifact
 For dd-trace-java you just need to set the `java.profiler.jar` project property.
