HP TestExportTool ask for dependencies continuously

Question

I have a LeanFT project, it is working properly, when I execute it from IDE. I generated a jar file with maven-assembly-plugin.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>3.1.0</version>
    <executions>
        <execution>
            <id>make-assembly</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <archive>
            <manifest>
                <mainClass>test.LeanFTest</mainClass>
            </manifest>
        </archive>
        <finalName>${project.artifactId}-fatjar-${project.version}</finalName>
        <appendAssemblyId>false</appendAssemblyId>
        <descriptors>
            <descriptor>src/main/assembly/leanft-assembly.xml</descriptor>
        </descriptors>
    </configuration>
</plugin>

When I try to execute it by TestExportTool(to generate XML file for ALM import) I get various error messages, like:

log4j: WARN JmDNS or serviceInfo not found

java.lang.UnsatisfiedLinkError: no NTEventLogAppender

java.lang.NoClassDefFoundError

I imported all the necessary classes, resolved these issues, but TestExportTool comes with exceptions again and again. I added these dependencies, reported by error messages, but these are not used by project, so not sure why it is asking for.

   <dependency>
        <groupId>org.jmdns</groupId>

UPDATE 07.09.: I added all the dependencies, requested by TestExportTool. I get following message from Hewlett-Packard Enterprise LeanFT Test Export Tool:

Answer 1

Sounds like the NTEventLogAppender.dll is not available on the PATH. More details on how and why Log4J might be using it here - it's available in the .zip download file.

However, this only applies to Log4J (v1.2) as opposed to Log4J 2 - it looks like this is what's wanted in those dependencies? For Log4J 2 the SLF4J binding should be org.apache.logging.log4j:log4j-slf4j-impl:2.11.0 (instead of org.slf4j:slf4j-log4j12:1.7.25).

Answer 2

By default maven does not include in the generated jar all the dependencies. It always assumes that those already exist in the target System. You have 2 possibilities:

1. Paste those jar files to the Target Systems $classpath / libs folder
2. Configure your maven project to export all dependencies as part of the jar (This will make your jar file explode)
3. Not recommended: Copy the jar files to the lib\ext folder of your jre running your ALM System. These will be loaded into every application using this jre.

Answer 3

Problem caused by JAR generation plugin in IntelliJ IDEA. I exported same project to Eclipse and generated JAR file under File -> Export option and file is working fine when executed from ALM.
