Springboot - Gradle task for buildpacks new-relic

[kenwiths]

I want to import new-relic into my spring-boot-app image without to use "COPY new-relic.jar" in Dockerfile for runImage. I tried this task in build.gradle:

bootBuildImage {
    builder = "paketobuildpacks/builder:tiny"
    buildpacks = [
            "gcr.io/paketo-buildpacks/ca-certificates",
            "gcr.io/paketo-buildpacks/amazon-corretto",
            "gcr.io/paketo-buildpacks/syft",
            "gcr.io/paketo-buildpacks/executable-jar",
            "gcr.io/paketo-buildpacks/dist-zip",
            "gcr.io/paketo-buildpacks/spring-boot",
            "gcr.io/paketo-buildpacks/new-relic"
    ]
    environment = [
            "BP_JVM_VERSION" : "17.*",
            "BPL_SPRING_CLOUD_BINDINGS_DISABLED": "true",
            "JAVA_TOOL_OPTIONS": "-XX:ActiveProcessorCount=4"
    ]
    runImage = "paketobuildpacks/run:tiny"
}

Then run with this command:
./gradlew bootBuildImage -p apilayer/ --imageName="test"

And the Error return below:

I think paketo-buildpacks/new-relic not incompatible with my app. But I still want to ask u guys this solution is good ? or any ideas for this ?

Spring boot 2.7.9
Java 17 corretto

Short answer: you need to include a binding for the New Relic buildpack to detect properly.

A binding exists with type of NewRelic

https://github.com/paketo-buildpacks/new-relic/#behavior

See this doc page for details on bindings. In a nutshell, a binding is just a folder with files. One file called type with a value of NewRelic and then additional files for settings you want to pass to the New Relic buildpack, where the name is the key and the contents are the value. For example, a file called license_key with the contents of <your license> would get passed through to New Relic as it's license key (it's passed through via an env variable NEW_RELIC_LICENSE_KEY which is automatically set).

You then need to set the binding as a volume mounted to the app at build time and at runtime. At build time, you can do that by adding bindings = ['${projectDir}/bindings/new-relic:/platform/bindings/new-relic'] to the bootBuildImage section in your build.gradle file. At runtime, it depends on how you're running the container image but with docker it's the --volume argument for docker run.
