Run main of specific class inside a package subdirectory
I am following Scheduled Jobs with Custom Clock Processes in Java with Quartz and RabbitMQ but I struggle to actually run another dyno from withing the jar file packeg by Spring.
In the package (server-1.0-SNAPSHOT.jar) I need to run the company.server.Scheduler. The .class file is in BOOT-INF/classes.
I've tried to do this but I am always getting
Error: Could not find or load main class company.server.Scheduler
I'm struggling to get the syntax right.
So what I need to run is
BOOT-INF/classes/company/server/Scheduler.class
I have tried this:
java -classpath BOOT-INF/classes -jar server-1.0-SNAPSHOT.jar company.server.Scheduler
java -classpath server-1.0-SNAPSHOT.jar:/BOOT-INF/classes company.server.Scheduler
But this either runs the main class from the Manifest or crashes.
Also tried:
java -classpath server-1.0-SNAPSHOT.jar BOOT-INF.classes.company.server.Scheduler
java -classpath server-1.0-SNAPSHOT.jar BOOT-INF/classes/company/server/Scheduler
Try it out ...
git clone https://github.com/silentsnooc/run-scheduler
cd run-scheduler/
mvn clean install
cd target/
java -cp .:scheduler-test-1.0-SNAPSHOT.jar BOOT-INF.classes.Scheduler
If I follow this on Heroku then it should be something like
java -cp scheduler-test-1.0-SNAPSHOT.jar:BOOT-INF/classes/* Scheduler
but it's not working telling me the main class Scheduler could not be found.

isBOOT-INF/classesa folder inside the jar?
– Timothy Truckle
Dec 29 '18 at 18:38
@TimothyTruckle Yes. This jar file gets packaged by Spring which is moving all the compiled stuff intoBOOT-INF/classesafaik.

@TimothyTruckle Just tried it. It does not work unfortunately. Could it be becauseBOOT-INFis not a vaild package name?
