[MJAVADOC-594] aggregate-jar fails on attached artifacts created by projects in the reactor build

**[Steinar Bang](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=sb@dod.no)** opened **[MJAVADOC-594](https://issues.apache.org/jira/browse/MJAVADOC-594?redirect=false)** and commented

I have a multi-module project that have modules with attachments of type "xml" and classifier "features".

When modules in the reactor build have dependencies to xml features attachments of other modules like e.g. this:

```xml

no.priv.bang.authservice
authservice.definitions
${project.version}
xml
features

```

and an aggregate-jar configuration like this:

```xml

org.apache.maven.plugins
maven-javadoc-plugin

private



attach-javadocs

jar



aggregate-javadocs

aggregate-jar

prepare-package

```

the build fails early with the following error message:

```

**Affects:** 3.1.0

**Remote Links:**
- [git branch reproducing the bug
](https://github.com/steinarb/authservice/tree/bug/mjavadoc-594)

Start by reproducing the failure with the linked bug/mjavadoc-594 branch and the aggregate-jar configuration shown in the issue. Trace how reactor dependencies for attached XML artifacts with the features classifier are resolved. Done means the reactor build resolves those attachments and aggregate-jar completes successfully.
