Scoverage-maven no longer works with Scala-maven-plugin version 4+

[aseigneurin]

The following error appears:

Execution scala-compile-first of goal net.alchim31.maven:scala-maven-plugin:4.0.1:compile failed: A required class was missing while executing net.alchim31.maven:scala-maven-plugin:4.0.1:compile: scala/xml/NamespaceBinding

This is when using:

• scoverage-maven-plugin version 1.3.0
• scala-maven-plugin version 4.0.1

It appears to me that scala-maven-plugin no longer depends on scala-xml (I read something along these lines in scoverage/scalac-scoverage-plugin#225.

Let me know if I can provide additional information to help fix this issue.

Hi @aseigneurin

Quick workaround is to use latest (1.4.0-M5 now) scalac plugin version, e.g.:

            <plugin>
                <groupId>org.scoverage</groupId>
                <artifactId>scoverage-maven-plugin</artifactId>
                <version>${scoverage.plugin.version}</version>
                <configuration>
                    <scalacPluginVersion>1.4.0-M5</scalacPluginVersion>
                    <highlighting>true</highlighting>
                </configuration>
            </plugin>

Proper solution would be to release Maven plugin version 1.4.0-M5 (using this version of scalac plugin internally).

Sorry, unfortunately the workaround does not work. Report is not generated.

1.4.0-SNAPSHOT snapshot deployed. Please verify if it works for you with new scala-maven-plugin versions.

[gslowikowski]

Version 1.4.0-M5 released. M5, because it supports Scala 2.13.0-M5.

Sorry for the delay. I can confirm the issue is resolved with 1.4.0-M5.

Thanks for your help.
