Have Quarkus buildpack set env variable to ensure executable-jar buildpack picks the correct JAR

[sebastiangraf]

When building the Sample Project located under https://github.com/paketo-buildpacks/samples/tree/main/java/native-image/quarkus-native with a local copy of this buildpack, the resulting image is not executable. The same applies for a more recent version of quarkus and jvm.

Expected Behavior

Checking out this repository under /tmp/quarkus and invoked via

cd buildpacks-samples/java/native-image/quarkus-native
pack build -B paketobuildpacks/builder:tiny -b /tmp/quarkus test-image

Result would be an image test-image that would be directly executable. When the image runs, something like

__  ____  __  _____   ___  __ ____  ______ 
 --/ __ \/ / / / _ | / _ \/ //_/ / / / __/ 
 -/ /_/ / /_/ / __ |/ , _/ ,< / /_/ /\ \   
--\___\_\____/_/ |_/_/|_/_/|_|\____/___/

should occur.

Current Behavior

Build runs, but is not compiling anything

Executing this image results in

ERROR: failed to launch: determine start command: when there is no default process a command is required

I guess that invoking the quarkus buildpack is not including the java buildpack as no compilation takes place.

Possible Solution

Including the quarkus buildpack directly int he java buildpack might solve the problem.

Steps to Reproduce

1. Clone samples repository: https://github.com/paketo-buildpacks/samples/tree/main/java/native-image/quarkus-native
2. Clone this repository: https://github.com/paketo-buildpacks/quarkus
3. Invoke the tiny-builder with a reference to this cloned buildpack executed on the samples.

Motivations

I try to build a quarkus app with the help of buildpacks :)

OK, can you try the following build command?

pack build -B paketobuildpacks/builder:tiny -b urn:cnb:builder:paketo-buildpacks/ca-certificates -b urn:cnb:builder:paketo-buildpacks/bellsoft-liberica -b urn:cnb:builder:paketo-buildpacks/syft  -b /tmp/quarkus -b urn:cnb:builder:paketo-buildpacks/maven -b urn:cnb:builder:paketo-buildpacks/executable-jar test-image

alternatively for native-image builds...

pack build -B paketobuildpacks/builder:tiny -b urn:cnb:builder:paketo-buildpacks/ca-certificates -b urn:cnb:builder:paketo-buildpacks/bellsoft-liberica -b urn:cnb:builder:paketo-buildpacks/syft  -b /tmp/quarkus -b urn:cnb:builder:paketo-buildpacks/maven -b urn:cnb:builder:paketo-buildpacks/executable-jar -b urn:cnb:builder:paketo-buildpacks/native-image test-image

When you use the -b argument, you need to feed in a full set of buildpacks to run. Because the Quarkus buildpack needs to run before Maven, we also have to insert it in the middle of the list which is a little messy (there's no easy way to do that on-the-fly with pack).

[matejvasek]

@sebastiangraf have you tried what @dmikusa suggested? Has it worked?

[anthonydahanne]

I followed your suggestion @dmikusa with:

 pack build -B paketobuildpacks/builder:tiny -b urn:cnb:builder:paketo-buildpacks/ca-certificates -b urn:cnb:builder:paketo-buildpacks/bellsoft-liberica -b urn:cnb:builder:paketo-buildpacks/syft  -b paketo-buildpacks/quarkus -b urn:cnb:builder:paketo-buildpacks/maven -b urn:cnb:builder:paketo-buildpacks/executable-jar test-image

and I ended up with:

docker run -it test-image

The default behavior, with no options specified, is to autogenerate an external index file

[dmikusa]

Can you include the output of pack inspect <app-img>? I'm curious what it has set as the process types 🤔 (UPDATE: after looking at the code, Quarkus bp isn't setting any process types so those would be set by another buildpack, still an interesting data point though).

It looks like it is building and running some command, but that command is failing and complaining about the arguments.

It would also be helpful to get the full build log.

[anthonydahanne]

no problem.

I have removed the thousdans of Downloading lines from Maven output; also you'll notice an issue downloading an artifact, but that does not seem to harm the build 🤷

[dmikusa]

Sorry for the delayed response. Is /workspace/lib/main/io.smallrye.jandex-3.1.1.jar the right JAR to execute the app? The executable-jar buildpack is picking that, mostly likely because it contains a Main-Class entry in MANIFEST.MF. It can sometimes happen that it picks the wrong JAR file. I'm suspicious because it's under /workspace/lib/.... You can also see in the previous output that it's running jandex on start and that is just not doing anything, which further supports the hypothesis that it's picking the wrong JAR.

Usage: jandex [-v] [-m] [-o file-name] <directory> | <jar>
        -or-
       jandex [-d] <index-file-name>
...

There is an issue to make the JAR it picks more configurable, but that's not been implemented yet. http://github.com/paketo-buildpacks/executable-jar/issues/206.

[anthonydahanne]

Yeah, that was probably it; it picked a random jar with a declared Main-Class.

once paketo-buildpacks/executable-jar#206 is fixed I suggest this issue becomes about having quarkus contribute the new env. variable so that execute-jar will choose to use the right jar
