quarkus-bootstrap-maven-plugin:build-tree requires installed project in local maven repository

[rsvoboda]

quarkus-bootstrap-maven-plugin:build-tree requires installed project in local maven repository, otherwise it fails with message similar to this: Failed to resolve application model org.acme:getting-started::jar:1.0-SNAPSHOT dependencies: Failed to resolve artifact org.acme:getting-started:jar:1.0-SNAPSHOT: Could not find artifact org.acme:getting-started:jar:1.0-SNAPSHOT

Quarkus 1.3.4 based quarkus-bootstrap-maven-plugin:build-tree command doesn't require to install local project into local maven repository first.

Workaround is to call mvn clean install before calling quarkus-bootstrap-maven-plugin:build-tree.
It's a regression against Quarkus 1.3

Reproducer:

 mvn io.quarkus:quarkus-maven-plugin:1.8.1.Final:create \
 -DprojectGroupId=org.acme \
 -DprojectArtifactId=getting-started \
 -DclassName="org.acme.getting.started.GreetingResource" \
 -Dpath="/hello"
 cd getting-started

OK - mvn io.quarkus:quarkus-bootstrap-maven-plugin:1.3.4.Final:build-tree -Dmaven.repo.local=/Users/rsvoboda/Downloads/maven-repository-1.3/ -Dquarkus.platform.version=1.3.4.Final -Dquarkus-plugin.version=1.3.4.Final

FAIL - mvn io.quarkus:quarkus-bootstrap-maven-plugin:1.7.3.Final:build-tree -Dmaven.repo.local=/Users/rsvoboda/Downloads/maven-repository-1.7/ -Dquarkus.platform.version=1.7.3.Final -Dquarkus-plugin.version=1.7.3.Final

Have you tried 1.8.1.Final? It should work.

[rsvoboda]

Yes I did, it didn't work too.

Here is the output:

The same when 999-SNAPSHOT gets used

Ah, it's because the project hasn't even been compiled, so there is no target/classes dir. The project's JAR artifact simply can't be resolved, literally no content anywhere. Changing the root artifact to POM in build-tree fixes the issue. Thanks!
