问题
I am writing a plug-in for Eclipse Oxygen that allows External Tools to be run directly from toolbar buttons. When I right click the project and click Run As Eclipse Application I get a pop-up that shows the following errors
javax.xml.ws
Missing Constraint: Import-Package: java.xml.bind; version="0.0.0"
Missing Constraint: Import-Package: java.xml.bind.annotation; version="0.0.0"
org.apache.xmlrpc
Missing Constraint: Import-Package: java.xml.bind; version="0.0.0"
If I click Continue, Eclipse launches with the plug-in and it operates correctly. I have tried following the advice here to open the 'Run Configuration' and select 'Add Required Bundles' (although using Add Required Plug-ins as there is no bundles button) but it doesn't help. I neither can see javax.xml.bind in the list nor a way to add it.
The project itself is very simple with the following dependencies
org.eclipse.core.runtime
org.eclipse.debug.ui
org.eclipse.jface
and extensions
org.eclipse.debug.core.launchers
org.eclipse.ui.commands
org.eclipse.ui.handlers
org.eclipse.ui.menus
I have listed the dependency hierarchy and javax.xml.bind is not listed.
How can I add the dependencies or clear the errors?
回答1:
It seems, these two packages (java.xml.bind and java.xml.bind.annotation) are missing in your target platform.
Adding the javax.xml.bind plug-in (which can be download from Eclipse Orbit, e. g. here) to your target platform should fix the problem.
