[ARCHETYPE-649] "[WARNING] CP Don't override file" when generating archetype with 3.2.1

[jira-importer]

Wolfgang Knauf opened ARCHETYPE-649 and commented

I do some maintenance work on the "wildfly-jakartaee-ear-archetype". After updating "maven-archetype-plugin" to 3.2.1, there are two warnings printed when creating a project from the archetype.

[WARNING] Don't override file ...\multi\project\multi\web\src\test\java\foo\bar\multi
[WARNING] CP Don't override file ...\multi\project\multi\web\src\main\webapp
 

I think the problem depends on the archetype-plugin version that creates the archetype JAR. Attached are the jar files from my local repository. One is created with archetype-plugin 3.1.2, the other with 3.2.1.

[^wildfly-jakartaee-ear-archetype-30.0.0.Final-SNAPSHOT_321.jar]

[^wildfly-jakartaee-ear-archetype-30.0.0.Final-SNAPSHOT_312.jar]

Note the size difference of the two jar files.

When creating a project from the archetype, the message appears with both 3.1.2 and 3.2.1, if the archetype jar was created with 3.2.1. It does not appear when the archetype jar was created with the 3.1.2 plugin.

 

Debug logging during generating of the project from the archetype seems to point me to the reason: with 3.2.1, the jar file contains a lot of entries for the directories. With 3.1.2, there are only entries for "real" files.

This seems to cause duplicates with the fileSets in "archetype-metadata.xml"

 

Here is the log when the archetype jar was created with 3.1.2:

 

[DEBUG] getFilesetArchetypeResources( "C:\Users\USERNAME\.m2\repository\org\wildfly\archetype\wildfly-jakartaee-ear-archetype\30.0.0.Final-SNAPSHOT\wildfly-jakartaee-ear-archetype-30.0.0.Final-SNAPSHOT.jar" )

And this is the output for an archetype created with 3.2.1:

Unfortunately, I don't have an easy to reproduce sample - the "wildfly-jakartaee-ear-archetype" contains some additional stuff.

 

For completeness, I attached[^archetype-metadata.xml] with several "fileSet" definitions.

Here is the slighly simplified source project, which reproduces the problem:

[^wildfly-jakartaee-ear-archetype_ARCHETYPE-649.zip]

 

In "pom.xml", there is a section where the archetype-plugin version can be defined:

        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-archetype-plugin</artifactId>
                    <version>3.2.1</version>
                    <!--<version>3.1.2</version>-->
                    <extensions>true</extensions>
                </plugin>
            </plugins>
        </pluginManagement>

 

Currently, it is "3.2.1", which reproduces the warning. If you build the archetype with "mvn clean install", you will see the warning already when a sample project is generated during the test.

Otherwise, you can create a project later with this command:

mvn archetype:generate -DarchetypeCatalog=local -DgroupId=foo.bar -DartifactId=multi -Dversion=0.1-SNAPSHOT -Dpackage=foo.bar.multi -DarchetypeGroupId=org.wildfly.archetype -DarchetypeArtifactId=wildfly-jakartaee-ear-archetype_ARCHETYPE-649 -DarchetypeVersion=30.0.0.Final-SNAPSHOT

Change the version to "3.1.2" and rebuild it, and there is no warning.

The warning seems to be caused by the fact that the project has modules. In a simpler archetype without modules, the problem does not happen.

Sent a pull request, though I don't know whether this is a good solution ;): #160

When we skip empty directory - we will break ARCHETYPE-289

I think I found a workaround to avoid the warnings:

In "archetype-metadata.xml" I had defined fileSets for e.g. "src/test/java" or "src/main/webapp", and those directories also contained java files files or deployment descriptors:

        <module id="web" dir="web" name="web">
            <fileSets>
                ...
                <fileSet encoding="UTF-8" packaged="true" filtered="true">
                    <directory>src/test/java</directory>
                </fileSet>
                <fileSet encoding="UTF-8">
                    <directory>src/main/webapp</directory>
                </fileSet>
                ...
            </fileSets>
        </module>

This caused the warnings.

My workaround: I added a "includes" filter for all those directories:

        <module id="web" dir="web" name="web">
            <fileSets>
                ..
                <fileSet encoding="UTF-8" packaged="true" filtered="true">
                    <directory>src/test/java</directory>
                    <includes>
                        <include>**/*.java</include>
                    </includes>
                </fileSet>
                <fileSet encoding="UTF-8">
                    <directory>src/main/webapp</directory>
                    <includes>
                        <include>**/*.xml</include>
                    </includes>
                </fileSet>
                ...
            </fileSets>
        </module>

Now the warning is gone.

Hope that my workaround is reasonable ;-)

I would like to keep this issue open though my problem seems to be resolved, because I still think there is some validation bug in the archetype plugin.
