Eclipse Version: 2022-03 (4.23.0) jdk-18.0.1.1
Exporting JavaDoc displays following error:
javadoc: error - error: invalid source release: 18
1 error
But using Maven the JavaDoc is processed correctly with no errors.
Any suggestions for how to correct the Eclipse problem would be appreciated.
Thanks
Make sure that in the dialog that is shown for Project > Generate Javadoc..., the field Javadoc command refers to the Javadoc executable of a Java 18 JDK.

I am getting an error in importing an existing gradle project - which has lombok as well, and the error while importing points to lombok line only.
How can I solve this error - so that importing of the project is successful?
If I comment that line - then it works but then lombok does not work for me.
Check for Java Home Directory shown in the Gradle loading window at the end - if that is shown as unknown then your problem solution is as follows:
In Oxygen-eclipse :
Go to eclipse.ini file and edit above -vmargs as follows:
-vm
C:\Program Files\Java\jdk1.8.0_65\bin\javaw.exe<YOUR JDK Path>
In any other eclipse version - make sure the Java Home Directory is set properly either using .ini file or via the eclipse preferences menu.
After starting Eclipe I see the following error message in the workspace/.metadata/.log
!ENTRY org.eclipse.core.runtime 4 0 2017-09-18 09:38:48.275
!MESSAGE Invalid input url:platform:/plugin/com.mountainminds.eclemma.ui/icons/full/eview16/coverage.gif
!STACK 0
java.io.IOException: Unable to resolve plug-in "platform:/plugin/com.mountainminds.eclemma.ui/icons/full/eview16/coverage.gif".
The message does not go away even after uninstalling or reinstalling the plugin.
Any ideas on how to resolve this?
Eclipse: Oxygen 4.7.0
EclEmma: 3.0.0
EclEmma became an Eclipse project and is now part of the Eclipse Java download packages. Due to the move, the plug-ins have been rename: com.mountainminds.eclemma.ui become org.eclipse.eclemma.ui.
If you use a workspace that have been used with EclEmma < 3.0.0 before,
start Eclipse with the option -clean and
reset all Java perspectives (coverage.gif is the icon of the Coverage view and could be referenced in the stored window/perspective layout).
This is the image the error is referring to.
Put it in the proper installation path on your machine and you'd be fine.
I am having trouble configurating Eclipse for MD 18.3 plugin development.
I have thoroughly followed the "MagicDraw 18.3 Developer Guide / Development in Eclipse" tutorial you can find inside MagicDraw\openapi section to set up Eclipse.
When launching MagicDraw with all plugins run configuration, it throws the following error and terminates:
!ENTRY org.eclipse.core.variables 4 120 2016-07-20 10:39:12.159
!MESSAGE Reference to undefined variable file_uri
caused by this line of the run configuration
-Dosgi.framework.extensions=reference:${file_uri:${workspace_loc:/MagicDraw/MAGIC_DRAW_INSTALL_DIRECTORY/lib/bundles}}/com.nomagic.magicdraw.osgi.fragment
However, \lib\bundles\com.nomagic.magicdraw.osgi.fragment_1.0.0.201601271815.jar
is existing
I'm running the demo license, but that shouldn't influence the configuration. Any suggestions?
UPDATE
Solved this issue, by replacing reference:${file_uri:${workspace_loc:/MagicDraw/MAGIC_DRAW_INSTALL_DIRECTORY/lib/bundles}}/com.nomagic.magicdraw.osgi.fragment with the actual path and enabling com.nomagic.magicdraw.platform.feature in the bundles tab of the run configuration.
Next Problem: The provided example plugins won't load, throwing
java.lang.NullPointerException at com.nomagic.magicdraw.plugins.XMLPluginDescriptorLoader.loadPluginDescriptorData(XMLPluginDescriptorLoader.java:172)
and therefore
ERROR PLUGINS - Failed to create plugin: My Plug-in 2
java.lang.ClassNotFoundException: myplugin2.MyPlugin2
Same message for both, the example plugins and my own plugin. I have checked the plugin.xml files and also experimentally enabled the run configurations > bundles > workspace checkbox.
Try to edit this line:
- Dosgi.framework.extensions=com.nomagic.magicdraw.osgi.fragment
Setting up a new clean Eclipse installation solved everything.

Apparently same problem is also described in:
Eclipse times out when trying to show Javadoc for classes in rt.jar
The solution to your problem might be similar; Eclipse is looking at probably the wrong JDK installation.
Try to add a reference to your local JDK in Preferences > Java > Installed JREs and removing the reference to your JRE.
I'm running java 1.6 in Eclipse on my Intel Mac. I'm using the 1.6.0 version under System/Library/Frameworks and set the default compiler to this in Eclipse.
How do I attach the source code?
First, I downloaded the 1.6 source from oracle, thinking I could attach that 'cause the installed 1.6 didn't have source.
When I click a java class to get the Source Code Editor, there are problems:
first, the top line says Compiled from File.java (version 1.5 : 49.0, super bit)
most important, when I attach the 1.6 source jar file, it gets an error:
An error has occurred. See error log for more details.
Unable to create resource org.eclipse.ui.internal.misc.ExternalProgramImageDescriptor#50417ba8
This also appears in the error log:
java.lang.ClassNotFoundException: org.eclipse.ui.internal.views.log.LogView
at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:506)
The Eclipse version is: Eclipse Java EE IDE for Web Developers.
Version: Helios Service Release 2
Build id: 20110218-0911
When I click for installation details, I get:
An internal error occurred during: "Fetching children of _SELF_".
Registry Directory not available: /Users/rfrail/Downloads/eclipse 2/p2/org.eclipse.equinox.p2.engine/profileRegistry.
I'm running Eclipse from my Download directory (it's worked fine in the past); however, there are 2 folders for Eclipse:
eclipse, and
eclipse 2.
So that looks like a source of confusion right there. Eclipse operates fine otherwise.
Can you help, please?
