Create install anywhere launcher from executable jar

Question

I have a jar file that is being created by Spring Boot. Application runs smoothly when run by command java -jar. I want to create an install anywhere launcher with this jar file.

What I have tried is to send the Spring Boot main class (PropertiesLauncher). The issue is that calling it like this won't load the nested jars inside my executable jar and also the loader.path doesn't seems to work.

Is there a way to call the executable jar like java -jar from the install anywhere launcher?

I was thinking that another option was to create an install anywhere launcher for a script file and inside have the java -jar call. So another question will be: How do I create an install anywhere launcher for a script file?

Answer 1

'execute command' step will do the trick:

Use this command line:

java -jar <path.to.jar.file>

Use EXECUTE_STDOUT, EXECUTE_STDERR and EXECUTE_EXITCODE built-in variables to catch errors and parse the jar's execution result.

Important notes:

You'll have to make sure your jar includes all of the dependencies (or at least set the classpath in the command line);

To include the dependencies within your jar using eclipse you can:

1. Export your project as a 'runnable jar file' and select the 'Extract/Package required libraries into generated JAR' option/s

2. Use Maven to build the project with dependencies; the maven-assembly-plugin is required.

The 'execute command' will work for batch/cmd/shell scripts as well, but you'll have to make sure the scripts are extracted to a local folder such as %TEMP% or /tmp before you can use them.

Goodluck
