spring boot with bluemix error: None of the buildpacks detected a compatible application

Question

Steps:

1. create new project with start.spring.io
2. run it localy - works
3. run gradle task jar
4. push jar to bluemix cf push demoWar.jar

Downloaded app package (20.1M) Staging... None of the buildpacks detected a compatible application Exit status 222 Staging failed: Exited with status 222 Destroying container

FAILED Error restarting application: NoAppDetectedError

TIP: Buildpacks are detected when the "cf push" is executed from within the dire ctory that contains the app source code.

Answer 1

Try two things: 1. Use the -p command to target your deployable artifact. This would look something like cf p APP_NAME -p PATH_TO_YOUR_WAR. I usually chain my build and deploy commands so: mvn clean package && cf p APP_NAME -p PATH_TO_YOUR_WAR.

2. If this doesn't work then you can specify a build pack. So cf p APP_NAME -p PATH_TO_YOUR_WAR -b SOME_BUILDPACK. You can see the available build packs by calling cf buildpacks.

Hope this helps.
