Hello I tried to build run wordinator in my ubuntu18, managed to build and run the jar from command line.

The output shows something related to the LogManager.. am i missing something?

I just tried running that command line under macOS and it worked without error, so not sure what the issue on Ubuntu might be. I don't have quick access to an Ubuntu environment so I can't quickly test it.

Can you do "java -v" and post it here?

Hello, thanks for replying, here is my version. ( i'm very poor in java just understand the coding, no libs no tools)

$ java --version
openjdk 11.0.4 2019-07-16
OpenJDK Runtime Environment (build 11.0.4+11-post-Ubuntu-1ubuntu218.04.3)
OpenJDK 64-Bit Server VM (build 11.0.4+11-post-Ubuntu-1ubuntu218.04.3, mixed mode, sharing)

Tried to add plugin to maven pom.xml as per this post:

https://danieljamesscott.org/all-articles/9-articles/37-missing-classes-when-running-shaded-jars-with-java-9.html

no luck..

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>3.2.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <transformers>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>org.wordinator.xml2docx.MakeDocx</mainClass>
                                <manifestEntries>
                                    <Multi-Release>true</Multi-Release>
                                </manifestEntries>
                            </transformer>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>

Tried also to add dependency as per log4j2 migration guides.. no luck

    <dependency>
      <groupId>org.apache.logging.log4j</groupId>
      <artifactId>log4j-api</artifactId>
      <version>2.11.1</version>
    </dependency>

the problem is related with running the jar using java 11. Running with older version is the option .

/usr/lib/jvm/java-1.8.0-openjdk-amd64/bin/java -jar ...

Not elegant but works
