I have a ploblem during the installation of Codename One plugin in Netbeans.
After the installation it says to restart the IDE.
After IDE restarts it's like if I've never installed the plugin: it asks me to install from the beginning.
NetBeans 12 on Windows 10 Pro.
NetBeans 12 changed a lot about the way plugins should be built and our plugin is a bit out of date by now.
However, we won't be updating it since it's no longer necessary as we migrated to maven. You can learn about that here: https://www.codenameone.com/blog/moving-to-maven.html
Using JBoss Studio and importing sample jboss-forge-html5-archetype. When you click next; shows that plugin AngularJS Eclipse needs to be installed. When I try Download and Install it fails. It says it is already installed.
Has anyone seen this issue before? Where does JBoss Studio keep it's log files? Where does JBOss Studio list it's plugins? How do you un-install a plugin?
Thanks!
Log files are stored the same way as plain Eclipse does. Check in your ~/devstudio/ folder for .log files, or check your workspace's folder for a .log file. Or check the Error Log view while running Devstudio.
To list installed plugins / features, from within Devstudio,select Help > About. You can also uninstall features (not plugins) from that dialog.
If a feature needed by a quick start is already installed then you shouldn't need to reinstall it... But maybe you need to update it?
What version of Devstudio are you running? Which OS & version? Which JDK vendor & version?
Does Eclipse juno require to have a Java EE environment pre installed to install the GAE plugin?
like everyone i get error like this
Cannot complete the install because one or more required items could not be found.

You need to update your juno releases first.
1. Then go to help-> Install new software.
Add -> this link and name it GAE . https://dl.google.com/eclipse/plugin/4.2
Now you will see some packages with checkbox. select Google plugin for app engine and SDK's.
3.Click finish and now your eclipse will download and install the needed packages.
Then you will find Google->web application project in Create new project menu.
I try to download Eclipse Juno (I havedownloaded Java version and install Web Development and Enterprise Development toolkits). After that, I install Google Plugin for Eclipse. When Eclipse check dependency, it notices error :
Missing requirement: Google Plugin for Eclipse 4.2
3.0.1.v201206290132-rel-r42 (com.google.gdt.eclipse.suite.e42.feature.feature.group
3.0.1.v201206290132-rel-r42) requires 'org.eclipse.mylyn.commons.ui 0.0.0' but it could not be found
I have google many times, but still cannot solve this problem. Who has experience in this problem, please tell me. This annoy me so much :(
Thanks :)
I had a different problem that lead to this error:
My fresh install of Eclipse Juno did not have the Juno repository in the list at all.
To fix this, simply add this repository's URL (http://download.eclipse.org/releases/juno/) to the "Work with:" edit box once, before installing the Google Plugins (and, of course, also make sure that the "Contact all update sites during install to find required software" checkbox is checked, as described by d60402).
Make sure the "Contact all update sites during install to find required software" checkbox is checked in the Eclipse, Install New Software dialog.
My case also differs in that I'm using Rational Application Developer (RAD) for WebSphere and I was trying to install Kotlin, but the solution was the same as the one described by Markus A.
Follow below steps
Help -> install new software -> add below url -> next

I just created a .jsp file in my google app engine project. How to resolve the below error.
Description Resource Path Location Type
Your project must be configured to use a JDK in order to use JSPs
proj1.jsp
/Proj1/war Unknown Google App Engine Problem
Kindly let me know.
it is the error. In order to compile jsp you need a jdk installed in your system. If you are running on a JRE you will get this error. Also make sure that your project has been configured with a jdk in it's path.

.jsp file not working for Google App Engine guestbook tutorial
the accepted answer was a year ago
updated answer from reference
In the end I seem to have wasted my bounty as I found the solution (with a little help) myself.
The problem arose because I was unfamiliar with Eclipse. When I found the more verbose error message Your project must be configured to use a JDK in order to use JSPs guestbook.jsp.
It was located in a tab called 'Markers' in pane found at the bottom of the Eclipse window.
It seems that Eclipse wasn't aware that I had installed the JDK.
In Eclipse I went to menu Window->Preferences->Java->Installed JREs . Eclipse had only one entry there named jre6 I clicked the Add... button Chose Standard VM and browsed to the base directory of the jdk (in my case C:\Program Files\Java\jdk1.6.0_20)
I rebuilt my project but the same error was there. I had forgotten to check the box that tells Eclipse to use the jdk instead of the jre.
As soon as I did that Eclipse rebuilt my project and the error was gone.
To solve this problem, first please confirm that JDK is already install on your computer. If it not available, go to Oracle JDK hompage to download and install it.
Then follow some steps to config JDK.
When JDK is configured, return eclipse and build project if you still get current error, I decide you are using JRE instead JDK. Choose Prefrences - Java - Install JRE - Un-check JRE and check JDK
Rebuild project
Hope this help!
Set JDK as your Installed JREs in Eclipse.
In Eclipse Window->Preference->Java->Installed JREs
Click on Add Button | Select VM ->Add JRE
Select Folder of jdk as "JRE Home" Directory.
Click OK.
Build your GAE Project
JFTR:
For those who use Ubuntu and OpenJDK, and may come here looking for help on the same issue: EVEN when it is called Open*JDK* (i.e. java-6-openjdk) actually you may have installed only the JRE part since they are on different packages, so you need to install also the JDK. For version 6 this is done via:
$ sudo apt-get install openjdk-6-jdk
Note that you may have yet an openjdk-6-jre in your system.
If your problem persist, you must sure that in your project use JDK library. Go to your project->click right->Build Path->Configure Build Path->Add library->JRE System Library->Select "Workspace default JRE (jdk1...)"->Finish, and in "Order and Export" UP your JDK Library above JRE Library. When you save your proyect it´s ok.
