Fatal Error building Java apps with JWrapper

Question

I have exported a jar (non-executable) from Eclipse 4.4 Luna as shown and have tried to use JWrapper to produce native apps for Windows, OSX and Linux. The command I used in terminal was

My-MacBook-Pro-:JWrapper me$ java -Xmx512m -jar jwrapper-00031607960.jar SpaceInvaders/InvadersGame.jar

the file system is as such:

and the xml file jwrapper-spaceinvaders.xml is as follows:

<!-- The name of the app bundle -->
<BundleName>SpaceInvaders</BundleName>

<!-- The specification for one app within the bundle -->
<App>
  <Name>SpaceInvaders</Name>
  <LogoPNG>SpaceInvaders/logo.png</LogoPNG>
  <MainClass>InvadersGame</MainClass>
</App>

<SupportedLanguages>en</SupportedLanguages>

<!-- App is a per-user app, it won't elevate and install for all users and the shared config folder will be per-user -->
<InstallType>CurrentUser</InstallType>

<!-- Splash and Logo -->
<BundleLogoPNG>SpaceInvaders/logo.png</BundleLogoPNG>

<!-- JVM options (e.g. extra memory) -->
<JvmOptions>
 <JvmOption>-Xmx256m</JvmOption>
</JvmOptions>

<!-- The JREs JWrapper should use for Windows, Linux32, Linux64... -->
<Windows32JRE>JRE-1.7/win32/jre1.7.0_05</Windows32JRE>
<Windows64JRE>JRE-1.7/win32/jre1.7.0_05</Windows64JRE>
<Linux32JRE>JRE-1.7/linux/jre1.7.0_13</Linux32JRE>
<Linux64JRE>JRE-1.7/linuxx64/jre1.7.0_13</Linux64JRE>
<Mac64JRE>JRE-1.7/macos64/jre1.7.0_45.jre</Mac64JRE> 

<!-- The files that the app wants to bundle, here we have just one which is a JAR file and we specify that it should be on the launch classpath -->
<File classpath='yes'>SpaceInvaders/InvadersGame.jar</File>

But I get the following error when trying to build from terminal using the above command:

JWrapper 00031607960
Resources not found (wrappers+lib), will extract jwrapper-00031607960.jar..

I'm wondering if maybe my JAR file isn't being built correctly by Eclipse because the sample app seems to build fine and I just modified the xml file based on the sample given.

Answer 1

The command typed in terminal is incorrect and the last part should give the path to the .xml file, not the .jar file
