Description

According to the docs (https://maven.apache.org/plugins/maven-invoker-plugin/install-mojo.html), maven-invoker-plugin is "thread-safe and supports parallel builds." However, when I build by multi-module project with -T 1C, I get an error like the following:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-invoker-plugin:1.10:install (integration-test) on project my-archetype: Failed to install project dependencies: MavenProject: com.tavianator:my-archetype:1.6-SNAPSHOT @ /home/tavianator/code/Project/my-archetype/pom.xml: Failed to install project artifacts: MavenProject: com.tavianator:my-project-2:1.6-SNAPSHOT @ /home/tavianator/code/Project/my-project-2/pom.xml: Failed to install artifact: com.tavianator:my-project-2:jar:1.6-SNAPSHOT: Artifact is not fully assembled: /home/tavianator/code/Project/my-project-2/target/classes -> [Help 1]

The project layout is like this:

Root
|--Project 1
|--Project 2
|--Archetype (depends on Project 1, scope=test)

The archetype integration tests use the maven-invoker-plugin to install the relevant dependencies (Root and Project 1) to a local repository, then runs the normal archetype integration tests. In parallel builds, Archetype and Project 2 run at the same time. When the maven-invoker-plugin runs, it tries to install Project 2 to the local repo, but Project 2 isn't built yet, hence the error.
