dontWrapJar causes 'Could not find or load main class'

[dhakehurst]

Hi,
great plugin, however I'm having some issues.
I wrap everything into a FAT jar, which I can execute fine.
I would like to create a .exe that executes the jar.

I want to end up with a directory structure of

app
 |--app.exe
 |--lib
      |-- app.jar

so I have created a configuration that looks like:

 <configuration>
      <headerType>console</headerType>
      <outfile>target/app.exe</outfile>
      <jar>lib/${project.artifactId}-${project.version}-FAT.jar</jar>
      <dontWrapJar>true</dontWrapJar>
      <classPath>
          <mainClass>${main-class}</mainClass>
          <addDependencies>false</addDependencies>
          <jarLocation>lib/</jarLocation>
      </classPath>
 </configuration>

I construct my desired directory structure using the assembly plugin.
The resulting directory structure is correct, however

If I run app.exe from the directory 'app' that the exe sits in, it works fine,
but if I run it from some other directory it gives the error

Error: Could not find or load main class com.itemis.fit.cli.MainCli
Caused by: java.lang.ClassNotFoundException: ....

How do I ensure that the location is relative to the .exe location, not the directory I run the exe from ?

I have discoved if I set <chdir>.</chdir>
then the exe can find the jar and it works.

Is this the correct thing to do?

I would prefer/expect the pwd to remain as the directory the user runs the exe from!

from top of my head could you try to use <jarLocation>./lib/</jarLocation>

<chdir>
Optional. Change current directory to an arbitrary path relative to the executable. If you omit this property or leave it blank it will have no effect. Setting it to . will change the current dir to the same directory as the executable. .. will change it to the parent directory, and so on.
