For example, you can download the jakarta.activation.jar file from the Jakarta Activation 1.2.2-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>
