I'm creating an application to automatically generate resources for a launcher, this requires automatically resolving maven dependencies, but I'm getting an UnsupportedOperationException while running JBoss Shrinkwrap Resolver
I'm running this inside a docker container, to avoid the local repository caching, it works outside of the container on the host, but I'm unsure what is missing inside the container.
My resolver config is a simple example, converting to a MavenResolvedArtifact
MavenResolvedArtifact[] artifacts = Maven.configureResolver()
.withMavenCentralRepo(true)
.withRemoteRepo("internal-nexus", MAVEN_URL, "default")
.resolve("com.company:application:" + PROJECT_VERSION)
.withTransitivity()
.asResolvedArtifact();
My Dockerfile is also relatively simple, using openjdk9, including the bootstrapper program, a shell script and some environment variables.
FROM openjdk:9
COPY bootstrapper-shaded.jar /bootstrapper.jar
COPY docker-run.sh /run.sh
ENV CLONE_URL https://github.com/company/repository.git
ENV NEXUS_BASE https://nexus.company.com/
ENV NEXUS_REPO repository
RUN chmod +x /run.sh
RUN apt-get update && apt-get install -y git software-properties-common maven
ENTRYPOINT ["/run.sh"]
And the run.sh script copies some files (removed for brevity), runs the build, then the bootstrapper
#!/bin/sh
rm -rf /boostrap/*
cd /bootstrap/
git clone $CLONE_URL work
cd work
chmod +x ./gradlew
./gradlew clean build
NEXUS_URL=`printf $NEXUS_BASE; printf "/repository/"; printf $NEXUS_REPO` ./gradlew upload
java -jar /bootstrapper.jar 0
I expect the output to be the same as on the host machine, an array of MavenResolvedArtifacts, however the following exception is thrown on the final line of the code snippet, .asResolvedArtifact()
Exception in thread "main" java.lang.UnsupportedOperationException: No format processor for org.jboss.shrinkwrap.resolver.api.maven.MavenResolvedArtifact was found. Supported processors are: class org.jboss.shrinkwrap.resolver.impl.maven.archive.ArchiveFormatProcessor

Apologies for any typos in the stacktrace, VM wouldn't let me copy-paste out of it so I had to type it out myself.
Update: Haven't found anything else on google yet, have tried clean builds to no avail.
