Angus - Activation


The Angus Activation is a compatible implementation of the Jakarta Activation Specification 2.1+ which lets you take advantage of standard services to: determine the type of an arbitrary piece of data; encapsulate access to it; discover the operations available on it; and instantiate the appropriate bean to perform the operation(s).

This project is part of Eclipse Angus project.

Development Releases

Snapshot builds of the next version of the Angus Activation under development are published to the Jakarta Sonatype OSS repository. These snapshot builds have received only minimal testing, but may provide previews of bug fixes or new features under development.

For example, you can download the angus-activation.jar file from the Eclipse Angus 2.0.0-SNAPSHOT release here. Be sure to scroll to the bottom and choose the jar file with the most recent time stamp.

You’ll need to add the following configuration to your Maven ~/.m2/settings.xml to be able to use these with Maven:

    <profiles>
        <!-- to allow loading Jakarta snapshot artifacts -->
        <profile>
            <id>jakarta-snapshots</id>
            <pluginRepositories>
                <pluginRepository>
                    <id>jakarta-snapshots</id>
                    <name>Jakarta Snapshots</name>
                    <snapshots>
                        <enabled>true</enabled>
                        <updatePolicy>always</updatePolicy>
                        <checksumPolicy>fail</checksumPolicy>
                    </snapshots>
                    <url>https://jakarta.oss.sonatype.org/content/repositories/snapshots/</url>
                    <layout>default</layout>
                </pluginRepository>
            </pluginRepositories>
        </profile>
    </profiles>

And then when you build use mvn -Pjakarta-snapshots ....

If you want the plugin repository to be enabled all the time so you don’t need the -P, add:

    <activeProfiles>
        <activeProfile>jakarta-snapshots</activeProfile>
    </activeProfiles>
