I´m beginning with Acceleo.
I installed eclipse-modeling-luna-M6-win32.
Then i installed acceleo by update on eclipse.
(is there any better option?)
Trying to use the uml2java example.
To run it i tried to run org.eclipse.acceleo.examples.uml2java.
It gave me:
Error
Couldn't load class org.eclipse.acceleo.examples.uml2java.main.Uml2java from project org.eclipse.acceleo.examples.uml2java
Couldn't load class org.eclipse.acceleo.examples.uml2java.main.Uml2java. Check that its containing package is exported.
I did not change the code.
I checked the MANIFEST and it has on the runtime: org.eclipse.acceleo.examples.uml2java.main
I also saw that there is an UI project that as i understand is a plugin but i don´t know what to do with it (so that it will create a new menu on eclipse).
Any help is appreciated!!
Thanks.
it worked using eclipse indigo with the latest acceleo. i don´t know if it´s possible to use a more recent eclipse version. also works with eclipse kepler.
This fixed the problem for me. Try adding the "bin/" directory to the Classpath in the Manifest file.
Right click the MANIFEST.MF file and "Open With >" "Plug-in Manifest Editor".
This gives some tabs at the bottom. Use the "Runtime" tab. On the bottom right of this screen there is a place to edit the classpath. Add "bin/".
I got this idea from Etienne's answer in: Can't generate java from UML using Acceleo in Eclipse

I had made an maven project and it worked fine.
Then I installed plugins
EclEmma Java Code Coverage,
PHP Development Tools (PDT),
Eclipse.orgSonarQube
Then I worked on some other project. When I again wanted to create an maven project,it threw the following error window which said
The selected wizard could not be started
reason
plug-in org.eclipse.m2e.core.ui was unable to load class
org.eclipse.m2e.core.ui.internal wizards.MavenProjectWizard
Removed SonarQube plugin .This solved the issue.
Now it works all fine.
But is there any other solution to this problem since I have to use sonar.
Click on eclipse help tab and open installation details search sonar and remove all related plugins.
That's not quite the right characterization of what it says on the page,Please check your .log file /path/workspace/.metadata/
Find the correct plugin which is causing this problem and update to compatible version of the plugin with eclipse version.
To find the hidden files in the workspace use Ctrl+H
I had the same problem, and I've tried so many solutions. But what I did to solve the problem, is that I just upgraded my Eclipse IDE (2019-06 to 2020-03) by following these steps (from https://wiki.eclipse.org/FAQ_How_do_I_upgrade_Eclipse_IDE%3F) :
You first need to add the new release's repository as follows:
1-1. Window > Preferences > Install/Update > Available Software Sites
1-2. Click 'Add'
1-3. Enter the URL https://download.eclipse.org/releases/2020-03/
1-4. Click 'Ok'
Help > Check for Updates
If updates are found, proceed through the install wizard and restart the IDE when
prompted. Otherwise, read carefully the error message to find out which component
is conflicting and establish your resolution strategy.
Note that the start splash screen may be cached and will not necessarily be
updated to the latest version after the IDE is restarted. Performing a full
relaunch should display the new version number.
I have maven project with javafx code. When I checkout this project to Netbeans, id cant find javafx packages even if I set "Default JavaFX" platform for this projeckt. But it finds javafx packages for new javafx project.
you must set the build path and adding the external .jar - file from you javafx path.
You need to add this:
jfxrt.jar
greetz
not really supported/implemented just yet on the netbeans javafx modules side.
See the relevant enhancements filed.
http://netbeans.org/bugzilla/show_bug.cgi?id=221184
http://netbeans.org/bugzilla/show_bug.cgi?id=222295
You must add some JARs to your project in order to build it.
Select "Properties" in your project and choose Libraries. There, select "Add JAR/Folder" and navigate to the JDK folder. There, inside jre/lib you find jfxrt.jar. Add it.
Now, javafx package is recognized.
What is the advantage with not having a build path in eclipse? Why is that setting default when it's like something you'd never use? It seems eclipse indigo was developed to make software development as obscure as possible. I just checked out a fresh copy of the project I checked in (called dungeonworld) this afternoon from another computer and automatically nothing works, can't compile, can't choose build path, can't add jre, can't add jdk, can't add that to project properties.
Is my eclipse broken? I can't believe this is happening, such an easy thing not feasible.
Nothing above solutions worked for me so i tried below
Right click on project >> properties >> project facets >> click on java
It looks like you did not add Eclipse project metadata files to your source control system, so Eclipse doesn't know what your build path is or whether it is even a java project. You can see that the little folder on your dungeonworld project is missing the little 'j', which means Eclipse doesn't think it's a java project.
Go back to your other computer and look for the following files in your original project root...
.project
.classpath
.settings/*
Make sure all of the end up in your source control system or nothing will work right.
I have same problem, but i have solved
project right click -> properties -> java build path -> src/main/sources
all remove items on "Excluded", and then that item turn the status "(None)"
I tried below steps and it works for me.
Right click on project >> properties >> project facets >> click on java
Eclipse has a build path.
It's stored in a (by default hidden) .classpath file in your project.
You can also access it through the UI in project properties (right click on your project, properties, java build path).
Well, this is probably not your problem, but similar is happening if you are in Eclipse different perspective (for example for Python).
vs.
There where no entrys after right click on my projekt in Eclipse. How to click something, wenn build path entries are missing. So my Eclpise didn't detect my java project. I used following Maven command and after that I cleaned the project too. Now Projekt works as expected. So...
If you are using Maven, try mvn eclipse:eclipse in cmd console in your project directory! Make sure to use the path to your Maven folder for the command.
For example:
cd C:\yourEclipseProject\
C:\yourPathToMaven\apache-maven-2.2.1\bin\mvn eclipse:eclipse
This was helping me. After unsuccessful web research, a coworker told me this tip.
I just had a similar problem and I figured out that I had been choosing General Project instead of Java Project while creating a project. After I chose Java>Project it solved my problem. Maybe it'll solve yours as well.
After choosing that, eclipse automatically included java libraries as well.
It's not a good practice to commit IDE related files into source control. What if someone in team uses different IDE? It might have been only option at a time when OP asked this question.
New versions on eclipse (4.x) takes care of this automatically. Probably by observing what kind of source and build files you have in your project.
Don't know the reason. But this works for me, so posting it.
Right click on project -> 'Properties' -> 'Java Build Path'.
I've followed this tutorial:
Eclipse Plugin
This tutorial explain why create a HTML Editor.
I need a Text editor,just for auto-highlight some words, anyway I thought this tuto should be a good one to start with.
The thing is that I created the Plugin project and the only thing that I changed it was the extension "pat" instead "html, htm", just that. After that I created a .pat file, but eclipse doesn't open it with my plugin, and my text editor is not in the editor's list.
Any suggestion??
Let me know if you need more information.
My guess is that you have just created the plugin, but aren't running it in your current Eclipse instance. That can be verified by opening the view "Plugin registry". That will show a list of all plugins, see if the plugin you have created is in that list.
If you click on the run button in Eclipse you will open a run configuration dialog. In one of the tabs, you get to choose what plugins should be available. Make sure your plug-in is selected. This will start up a new Eclipse instance that will run your plugin.
To make your plugin be a part of your ordinary Eclipse installation, you will need to export it to a jar and copy that jar to the dropins catalog.
I have a web app built with Maven.
Most of the time, I built the application using Intellij IDEA, but now I want to import the application in Eclipse to see something in this IDE.
After mvn eclipse:eclipse, I add in Eclipse the app, but when I try to add the app to the server (tomcat), I receive:
There are no resources that can be added or removed from the server
Solutions?
You need the project to have a Eclipse Dynamic Web Module facet. You can try doing this via the project properties dialog and looking at project facets, then clicking the appropriate check box. This may not be available however, so you may need to do the next thing.
Create a backup of your project and follow the directions at dzone.com. This'll allow you to modify the project facets via your eclipse .project file.
Keep in mind, once you add those facets, you cannot change them back via Eclipse. Definitely make sure you have a backup before starting.
This step worked for me:
Right-Click on the Project Name, then
Maven-->Update Project..
Click OK
After doing this I was able to see my project in Add/Remove Programs.
As mentioned somewhere else adding Eclipse WTP didn't do any good, however I performed the above step after I had already added Eclipse WTP, so I am guessing that may not be needed.
This was done for Eclipse Juno.
Hope this helps someone.
Edited: You can follow this link as above mentioned I think might have needed WTP and that add a lot of other things into the workspace.
http://blog.teamextension.com/maven-as-eclipse-dynamic-web-module-556
Check whether Maven Integration for Eclipse WTP is installed. If not, install it from Eclipse Marketplace
After installation restart Eclipse
Right click your project and Maven--> update project configuration
Delete tomcat and re create tomcat (clean tomcat,add your project,publish and enjoy)
I've got Tomcat 6, Java 1.6, and was trying to get it to work in Eclipse Juno Service Release 1's "internal server" (whatever that's called.) Here's what I did that worked for me:
(Found these instructions at http://www.mkyong.com/eclipse/eclipse-ide-tomcat-version-6-0-only-supports-j2ee-1-2-1-3-1-4-and-java-ee-5-web-modules/)
I should point out that I followed ClutchDude's instructions to make my project a Dynamic Web Module facet. It didn't work on its own for me, but maybe it was part of making it work in the end.
Using Eclipse (or other text editor), open the file
.settings/org.eclipse.wst.common.project.facet.core.xml
Find the line that reads
<installed facet="jst.web" version="3.0"/>
3.0 is for Tomcat 7.x (so says mkyong.) Change it to 2.5 (or 2.4).
I restarted Eclipse and it worked for my project.
The reason why this is happening is because eclipse by default looks for the deployment descriptor in the folder {project.home}/Webcontent/WEB-INF/web.xml where as the Maven puts them in src/main/webapp/WEB-INF/web.xml.
So when you are trying to add your project onto the server eclipse cannot find a deployment descriptor and hence you get the annoying message.
This can be solved by adding the following entries in .settings/org.eclipse.wst.common which can be found in
Project home folder in your workspace if it is a new maven project.
The folder where you already imported from if you are using Import -> Maven projects.
Make the following changes in to the org.eclipse.wst.common
wb-resource deploy-path="/" source-path="/src/main/webapp"/. Add this entry.
Edit --> property name="java-output-path"
Please check the following link from more details. http://java.dzone.com/articles/webapps-eclipse-and-maven.
The comments section has an excellent example with a working project.
This issue was fixed for me my installing additional eclipse modules. in particular, the ones related to m2e-wtp. just do a search for m2e in the plugins search listing for your version of eclipse
If you face an error like "There are no resources that can be added or removed from the server",
then
1) Go to the META_INF of your websvcsEAR and go to the application.xml.
2) Goto modules-> clickDetails and add the module that is existing. i.e., some EAR which your project demands.
3) Click ok
4) Now go to your server -> right click -> add and remove -> add your EAR.
Maybe you don't need add your application to the server's configuration. I think that you must use m2e eclipse plugin in order to launch the app.
For example, in your eclipse you will see a contextual menu called "Run as" if you right-click on your pom file. You can clicking on "Maven build" and Maven will download all the information needed to start tomcat.
I hope this helps you.
I used
mvn eclipse:eclipse -Dwtpversion=2.0
in command line in the folder where I had my pom.xml. Then I refreshed the project in eclipse IDE. After that I was able to add my project.
I was able to resolve this by removing my EAR project from my Eclipse workspace, then re-importing it.
Well, with a Spring and maven project, i got it that way:
Eclipse Version: 2019-06 (4.12.0)
Java 1.8
Tomcat 7
Yes, go to Project Properties >> Facets >> select Dynamic Web Module but dont apply yet!!!
Right under, it should appear a link Further Configuration Available. Click on it, otherwise one will have to edit .settings/org.eclipse.wst.common.component manually. Update source directory to src/main/java. (source)
Then in Facets window check Java - mine was pointing to 11 even though i don't have Java 11 installed or configured like a JRE runtime. I could only add/remove when changed to 1.8. (source). Note: That was really the problem, why don't Eclipse get this configuration automatically from the project?
Finally Eclipse creates some directories like WEB-INF and META-INF, just delete them.
