Hello, all! I little under two weeks ago, I posted with the subject "Extension works from lib/ext and CLI but not extensions.xml"
https://lists.apache.org/thread.html/23bea6ae06f17a3f256465e2c27a04ee9f90de3f49f21d20a627b85f@%3Cusers.maven.apache.org%3E Now I have reluctantly forked that extension to create my own https://github.com/imca-cat/profile-activation-advanced and have published to the Central Repository. Unfortunately, the same problem persists. But at least now there can be no question about trying to use an extension fetched from my local repository that had not been published to the Central Repository, and hopefully it will be easier for someone to try this and help figure out what's wrong (i.e., no need to build the extension). The extension works if I put its JAR in Maven's lib/ext directory, but it does not work when loaded via a project's .mvn/extensions.xml file. Having it work from .mvn/extensions.xml is critical for my intended use. Does anyone know why it doesn't work or what I could do to figure out why it doesn't work? To reproduce the problem, simply create a new Maven 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) || foo_env == "development"</value> </property> </activation> </profile> </profiles> </project> === Then create .mvn/extensions.xml: === <?xml version="1.0" encoding="UTF-8"?> <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>org.imca-cat.maven</groupId> <artifactId>profile-activation-advanced</artifactId> <version>0.1.0</version> </extension> </extensions> === Then run the following command: === $ mvn help:active-profiles validate === It should report that the foo_env-development profile is active === The following profiles are active: - foo_env-development (source: org.example.foo:foo:1.0.0) === but it does not === The following profiles are active: === If I place the extension's JAR file (and the JAR file for its mvel2 dependency) in Maven's lib/ext directory, it works: the command reports that the foo_env-development profile is active, which is the correct behavior. Thank you to anyone who can help!
