Eclipse 2019-03

Trouble

• xml-apis.jar
  • https://bugs.eclipse.org/bugs/show_bug.cgi?id=536928
  • https://bugs.eclipse.org/bugs/show_bug.cgi?id=544758
  • https://stackoverflow.com/questions/51094274/eclipse-cant-find-xml-related-classes-after-switching-build-path-to-jdk-10
• jaxen.jar, xercesImpl.jar
  • depend on of xml-apis.jar
• jlibs not ready for java11 yet: https://github.com/santhosh-tekuri/jlibs (25.04.2019)
• Log output of plug-in to FESA Console View is missing, TODO: https://stackoverflow.com/questions/54188518/log4j2-logging-level-becomes-different-in-java-8-and-java-11
• maven build works only without entries in MANIFEST.MF/Require-Bundle, but installed plug-in is not usable:

class cern.fesa.plugin.editor.DesignClassEditor cannot be cast to class org.eclipse.ui.IEditorPart (cern.fesa.plugin.editor.DesignClassEditor is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @2a57c508; org.eclipse.ui.IEditorPart is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @7c4eecfc)

• • adding module-info.java is no solution because the module system does not allow split packages (e.g. fesa.plugin.model / fesa.plugin.model.gsi or fesa.plugin.control / fesa.plugin.control.gsi export the same packages)
• Build within eclipse leads to following error:

/common/home/bel/matthies/lnx/eclipse-2019-03/.metadata/.plugins/org.eclipse.pde.core/temp/org.eclipse.pde.container.feature/compile.org.eclipse.pde.container.feature.xml:4: The following error occurred while executing this line:

Solutions

• a few code changes are required, ElementImpl, AttrImpl should not be used anymore in fesa.plugin.ui
• possible solution to allow debugging of plug-in's sources:
  • don't use maven build within eclipse, it does not properly work; stick to the 'old' way to build the plg-in within eclipse for debugging purposes
  • keep required libraries in fesa.plugin.ui/META-INF/MANIFEST.MF in Bundle-Classpath
  • remove troublesome libraries from project classpath
  • exclude the troublesome libraries from the maven dependencies in pom.xml for release build
