a mavent project convert from plugin have flow default rule
1. maven project prefer setting JRE to Execution environment, so .classpath is updated
2. java class compliment to target/classes/, so build.propertie is updated
3. JDK compliance configuration setting per project (only this option), so .settings/org.eclipse.jdt.core.prefs is created
extra setting about warning done manual to resolved
https://bugs.eclipse.org/bugs/show_bug.cgi?id=367431
it happend on bundle use non-standard java package
org.adempiere.base/.settings/org.eclipse.jdt.core.prefs
org.adempiere.ui.swing/.settings/org.eclipse.jdt.core.prefs
on org.adempiere.server, old method add accessrules to classpathentry don't work for maven build.
so change to warning method make it consitent with other
org.adempiere.server/.settings/org.eclipse.jdt.core.prefs
