When using maven to package a jar (unsure if it's a maven issue) the java ClassLoader can't find any resources.

Jar structure -

Value of test.class.getClassLoader().getResourceAsStream("") (or any other existing directory) is empty. No folders or files or found.

Maven Build Script:

<build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>9</source>
          <target>9</target>
        </configuration>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <executions>
          <execution>
            <goals>
              <goal>shade</goal>
            </goals>
            <configuration>
              <shadedArtifactAttached>true</shadedArtifactAttached>
              <transformers>
                <transformer implementation=
                                     "org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                  <mainClass>org.swordofsouls.discord.chatexporter.test</mainClass>
                </transformer>
              </transformers>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

Any help would be greatly appreciated.

Thanks

Tried using different ClassLoaders.

Value of Thread.currentThread().getContextClassLoader() is null.

Value of ClassLoader.getSystemClassLoader() is null.

The solution was to use / instead of File.separator
