Error running Spring Boot applications on Bluemix

I created a spring starter app using http://start.spring.io/, downloaded the zip, compiled using mvn install and pushed the jar to Bluemix :

cf push myspringapp1155 -p target/demo-0.0.1-SNAPSHOT.jar

The application does not start. The output of

cf logs myspringapp1155 --recent shows:

2015-07-10T11:13:30.25-0400 [App/0]      ERR Exception in thread "main" java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=demo/DemoApplication, offset=6

Bluemix now supports 1.8 in Liberty build pack. Hence simple cf push command can deploy the app into bluemix using Liberty java.

jar, war and ear files on Bluemix are handled by the Liberty buildpack by default on Bluemix. The Liberty buildpack currently uses Java 1.7 (This might change soon). You can either:

  • Compile your source using 1.7. Edit your pom.xml <java.version>1.7</java.version> or

  • Use the JBP_CONFIG_OPENJDK environment variable to specify an alternative version of the JRE. For example, to use the OPENJDK 8 set the following environment variable: $ cf set-env myapp JBP_CONFIG_OPENJDK "version: 1.8.+"
