We have a microservices project which was running (in Karaf) and building with JDK 8.
Now I am trying to build it with JDK 11 (OpenJDK in fact) but I am getting this error.

Does that mean this plugin is not compatible with JDK 11?

Or does it mean something else?

On the official page of the plugin I do not see any info if the plugin is compatible with JDK 11. The plugin latest version seems to be 1.10.0 and that's the one I am trying to use (but that was last build in 2018 so was it replaced with something else?).

I've just falled into several similar issues with blueprint-maven-plugin when migrating karaf-deployed projects from jdk8 to jdk11. As the blueprint-maven-plugin is still at version 1.10.0 since May 2018, following discussion within these issues

i have a workaround by overriding version of org.apache.xbean:xbean-finder-shaded to the latest version for the blueprint-maven-plugin:

<pluginManagement>
    <plugins>
        ...
        <plugin>
            <groupId>org.apache.aries.blueprint</groupId>
            <artifactId>blueprint-maven-plugin</artifactId>
            <version>1.10.0</version>
            <dependencies>
                <dependency>
                    <groupId>org.apache.xbean</groupId>
                    <artifactId>xbean-finder-shaded</artifactId>
                    <version>4.20</version>
                </dependency>
            </dependencies>
        </plugin>
