Failure in building local xwiki-platform

mousavil · April 20, 2025, 1:18am

Hello,

I encountered several issues when trying to build the XWiki project and run integration tests on my local XWiki instance with version 10.8. I faced an error related to the Spoon package with a snapshot that could not be fetched from a repository, as the repository at fr.irnia responded with an HTTP 500 error to my request.

Although I preferred to work with version 10.8, after spending hours dealing with this issue, I decided to switch to the stable versions 15.x, 16.x, and 17.x. However, I was unable to successfully build any of these versions using Maven 3.6.3 or 3.9.

For version 17.2.2 with Maven 3.6.3, I encountered the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-enforcer-plugin:3.5.0:enforce (enforce-valid-poms) on project xwiki-platform: Execution enforce-valid-poms of goal org.apache.maven.plugins:maven-enforcer-plugin:3.5.0:enforce failed: Failed to create enforcer rules with name: externalExtensionCheck or for class: org.apache.maven.plugins.enforcer.ExternalExtensionCheck -> [Help 1]

For Maven 3.9+, I received this error:

Unresolved plugin: 'org.xwiki.platform:xwiki-platform-tool-packager-plugin:17.2.2'

Is there a specific Docker container in which I can successfully build the source? My goal is to run integration tests for the entire platform and capture HTTP requests, function calls, traces, and SQL queries using XRebel.

mousavil:

For version 17.2.2 with Maven 3.6.3, I encountered the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-enforcer-plugin:3.5.0:enforce (enforce-valid-poms) on project xwiki-platform: Execution enforce-valid-poms of goal org.apache.maven.plugins:maven-enforcer-plugin:3.5.0:enforce failed: Failed to create enforcer rules with name: externalExtensionCheck or for class: org.apache.maven.plugins.enforcer.ExternalExtensionCheck -> [Help 1]

Not sure what this error means. If you build with -e you should have a more detailed error.

You might be missing the XWiki nexus repository in your settings.xml, as described on https://dev.xwiki.org/xwiki/bin/view/Community/Building/#HInstallingMaven. If you have the right settings, you might want to try again as there was some work on the nexus repository 2 days ago I think.

I have the same thing with the maven provided by Debian Trixie, with a project whose parent is org.xwiki.contrib:parent-platform:17.5.0:

It works with the same maven version as provided at Download Apache Maven – Maven

I didn’t manage to find which jar package contains that missing org.apache.maven.plugins.enforcer.ExternalExtensionCheck class.

I tried to install all the libmaven-* package (which pulls a lot of things):

sudo apt install 'libmaven-*'

But this doesn’t address the issue.

Could it mean that this externalExtensionCheck rule has a dependency that is not specified in its pom and that happens to be provided by the official distribution of maven but not by the Debian maven packages? Maybe it’s a Debian packaging bug?

tmortagne · August 27, 2025, 9:59am

This is a class of the enforcer plugin, so it’s not part of Maven itself.

rjakse · August 27, 2025, 11:12am

Is it supposed to be provided by Debian -- Details of package libmaven-enforcer-plugin-java in trixie and it’s actually not?

I suspect a Debian packaging bug in some way or another, but my knowledge in this stuff is very limited.

tmortagne · August 27, 2025, 11:28am

Is it supposed to be provided by Debian – Details of package libmaven-enforcer-plugin-java in trixie and it’s actually not?

Plugins are supposed to be downloaded during the build (i.e. you should find it in the local Maven repository), what decides which plugin version to use is what is indicated in the pom.xml, nothing to do with the version of Maven.

rjakse · September 2, 2025, 7:43am

ok, so for some unknown reason, something fails with Debian’s provided maven, and doesn’t with a maven downloaded from its website.

Now that Trixie is released, I suppose more people are going to hit this and be confused, so maybe this needs to be documented somewhere, maybe there: https://dev.xwiki.org/xwiki/bin/view/Community/Building/#HInstallingMaven. WDYT?

Hello

I have the exact same issue with XWiki 17.10.4 on ubuntu, impossible to build the platform or XWiki common or skip the enforcer maven plugin.

[INFO] XWiki Platform - CKEditor - Webjar ................. FAILURE [01:47 min]

Also inconsistency in building ckeditor that request jdk 15 or lower despite I build XWiki 17.10.4 that require jdk 17

But this is not the cause of the error

fix

export JAVA_TOOL_OPTIONS=“-Djava.awt.headless=true”

apache-maven-3.9.13/bin/mvn clean install -Dtest=none -DfailIfNoTests=false
-rf :xwiki-platform-ckeditor-webjar -e
