* IDEMPIERE-4298: remove Bundle-RequiredExecutionEnvironment
when build by tycho value of Bundle-RequiredExecutionEnvironment and jdt need to compatibility
in case we use Bundle-RequiredExecutionEnvironment = 11 then can't build by jdk != 11
so stick on fix value isn't good
eclipse now also support Require-Capability, so don't need Bundle-RequiredExecutionEnvironment anymore
* IDEMPIERE-4298:support update jdk (jdk 12 13 14)
default environment still jdk-11 but you can build for any jdk by below command
export JAVA_HOME=path to jdk
mvn verify -Djdk.version=11
in case on JAVA_HOME is jdk 14 then can set jdk.version for 11, 12, 13, 14 and same for other jdk
at moment java 14 just support on eclipse 2020-03 with install plugin
Java 14 Support for Eclipse 2020-03 (4.15)
