I have a problem with packing my maven selenium project in a standalone jar-file. There is no cp for testclasses despite being in jar file - selenium

Question

I try to pack my maven selenium autotest project into a standalone jar. I use the next main class to start test classes:
public static void main(String[] args) {
InvocationRequest request = new DefaultInvocationRequest();
request.setPomFile(new File("pom.xml"));
request.setGoals(Collections.singletonList("install"));
Invoker invoker = new DefaultInvoker();
invoker.setMavenHome(new File(System.getenv("MAVEN_HOME")));
try {
invoker.execute(request);
} catch (MavenInvocationException e) {
e.printStackTrace();
}
}
I have no problem with this, the tests are perfectly running from the mainclass. The next step is to pack the project into a jar-file. So I use maven-jar-plugin and maven-assembly-plugin for that purpose:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>test-jar</goal>
</goals>
</execution>
</executions>
</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>common.MainClass</mainClass>
</manifest>
</archive>
<appendAssemblyId>false</appendAssemblyId>
<descriptors>
<descriptor>src/test/resources/assembly.xml</descriptor>
</descriptors>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M5</version>
<configuration>
<suiteXmlFiles>
<suiteXmlFile>testng.xml</suiteXmlFile>
</suiteXmlFiles>
</configuration>
</plugin>
</plugins>
</build>
and my assembly:
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
<id>test-jar-with-dependencies</id>
<formats>
<format>jar</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<outputDirectory>/</outputDirectory>
<useProjectArtifact>true</useProjectArtifact>
<!-- we're creating the test-jar as an attachement -->
<useProjectAttachments>true</useProjectAttachments>
<unpack>true</unpack>
<scope>test</scope>
</dependencySet>
</dependencySets>
<fileSets>
<fileSet>
<directory>${project.build.directory}/test-classes</directory>
<outputDirectory>/</outputDirectory>
<includes>
<include>*.class</include>
</includes>
<useDefaultExcludes>true</useDefaultExcludes>
</fileSet>
</fileSets>
</assembly>
I manage to pack both common and test classes in a jar-file. I manually put the pom file and the testing file in the same directory as the jar file, so I have no trouble with starting the project. But the tests don't run, because the test-classes are not found, despite being inside the project.
I will be very appreciative if anyone gives me a clue about what I do wrong.
P.S. I put here a refer to my project: https://bitbucket.org/Max1203/donatiton-script.git

Answer 1

Test class not found may be misconfiguration
Can you reimport maven dependencies it will solve
Maven cycle-Reload All maven projects

Answer 2

In case anybody needs the answer. Just change the code in MainClass to the next one:
TestNG testNG = new TestNG();
testNG.setTestSuites(Arrays.asList("testng.xml"));
testNG.setPreserveOrder(true);
testNG.run();
It is gonna solve the problem.
