I am trying to migrate our bnd(OSGI) project from java 8 to 9. After first fail i have prepared basic project. However, I got stuck in problems with java versions capability, exacly like bellow (just a part of them, but all are the same with difference to the java version):
! Failed to start bundle org.apache.felix.gogo.command-1.0.2, exception

First what I have done was update all dependencies - didn't help though. I have googled a lot, but with just a few links resulted. The one which was the closest to the problem didn't help thought - I have added following lines, without result:
Bundle-RequiredExecutionEnvironment: JavaSE-9
Provide-Capability: osgi.ee;osgi.ee="JavaSE";version:List="1.0,1.1,1.2,1.3,1.4,1.5,1.6,1.7,1.8,9"
Maybe upgrade my bnd gradle plugin would help, however the version (I am currently using 3.5) mentioned (4.0) at readme is not available in mavenCentral.
Eclipse Oxygen.3a Release (4.7.3a)
Bndtools 3.5.0.REL
Java 9.0.4+11
OSGI 6.0
Gradle 4.4
Gradle bnd plugin - 3.5
BTW: If you are trying to run project in Intellij, problems can occur - at least we didn't cope to run our main project.
Any help would be appreciated, I will do my best to provide you more info if required.
Even when i delete nearly all dependencies (cleaned branch), after launch run.bndrun I am receiving only
could not resolve the bundles: [project.main-1.0.0.201804171613 org.osgi.framework.BundleException: Could not resolve module: project.main [3]
Unresolved requirement: Require-Capability: osgi.ee; filter:="(&(osgi.ee=JavaSE)(version=1.8))"
]
Failed to start bundle project.main-1.0.0.201804171613, exception Could not resolve module: project.main [3]
Unresolved requirement: Require-Capability: osgi.ee; filter:="(&(osgi.ee=JavaSE)(version=1.8))"
project.main is my only bundle.
As i mentioned in a comment we have dedpendency to enroute 2.0, which provides old version of org.eclipse.osgi. After manual update to 3.13 problems with Require-capability have disappeared.
