Not sure but I think the mechanism extension does not work for SNAPSHOT

No. There is something else different/wrong...
Try to install a non SNAPSHOT version in your local maven repository.
I think I have already faced the same in the past while producing with my
own extension https://github.com/jgitver/jgitver-maven-plugin
Hope it helps.

Hello, all!
I'm trying to use the EL Profile Activation Maven Extension
https://github.com/kpiwko/el-profile-activator-extension
to activate a profile when the foo_env system property is either not
set, or set to "development". I'm using the "help:active-profiles" goal
of the Maven Help plugin and the "validate" phase to test whether or not
a profile is active.
The extension works when I install it in
<maven-home>/lib/ext
and it works when I specify it on the command line with
-Dmaven.ext.class.path=<paths-to-extension-jars>
but it does *not* work when I put it in the project's
.mvn/extensions.xml
Does anyone know why?!
This is Maven 3.5.4, the latest Git snapshot of EL Profile Activation
Maven Extension, and MVEL 2.4.2.Final.
The el-profile-activator-extension artifact is not published in the
Central Repository, but I installed it into my local repository (i.e.,
~/.m2/repository) with
git clone https://github.com/kpiwko/el-profile-activator-extension.git
cd el-profile-activator-extension
: JAVA_HOME has been set to a Java 8 SDK to compile
mvn install
That should be fine, right? My local repository will be searched first
for any artifacts listed in extensions.xml, and I don't get a warning
nor error about it not being found, so my understanding is that this is
OK.
For the case where the extension does not work, I have a test-01 project
directory containing the following pom.xml file
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd";>
<modelVersion>4.0.0</modelVersion>
<groupId>org.example.foo</groupId>
<artifactId>foo</artifactId>
<version>1.0.0</version>
<packaging>pom</packaging>
<profiles>
<profile>
<id>foo_env-development</id>
<activation>
<property>
<name>mvel</name>
<value>(!isdef foo_env) || (isdef foo_env && foo_env
== "development")</value>
</property>
</activation>
</profile>
</profiles>
</project>
and the following .mvn/extensions.xml file
<extensions xmlns="http://maven.apache.org/EXTENSIONS/1.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://maven.apache.org/EXTENSIONS/1.0.0
http://maven.apache.org/xsd/core-extensions-1.0.0.xsd";>
<extension>
<groupId>com.redhat.jboss.maven</groupId>
<artifactId>el-profile-activator-extension</artifactId>
<version>1.0.0-SNAPSHOT</version>
</extension>
</extensions>
I invoke Maven like this
mvn help:active-profiles validate
and it shows that the foo_env-development profile is not active (i.e.,
it lists no active profiles)
The following profiles are active:
but it should be!
A transcript of this and with the "-X" option is attached as
test-01-extensions-dot-xml.txt
Removing the .mvn directory and adding
el-profile-activator-extension-1.0.0-SNAPSHOT.jar
and
mvel2-2.4.2.Final.jar
to
<maven-home>/lib/ext
works; i.e., it shows that the foo_env-development profile is active
The following profiles are active:
- foo_env-development (source: org.example.foo:foo:1.0.0)
A transcript of this and with the "-X" option is attached as
test-01-maven-home-lib-ext.txt
Removing those JARs from
<maven-home>/lib/ext
and instead specifying them on the command line by setting the
maven.ext.class.path
system property works; i.e., it shows that the foo_env-development
profile is active
The following profiles are active:
- foo_env-development (source: org.example.foo:foo:1.0.0)
A transcript of this and with the "-X" option is attached as
test-01-maven-ext-class-path.txt
Any help getting the extensions.xml case to work would be greatly
appreciated! Thank you!
