I created new classes by right clicking on a package. The package seems correct in the actual code in the classes, but the new classes can't be seen in the package in the Project Explorer.
What's going on?
Right click on the project name in the Project Explorer and hit 'refresh'. I had this problem before too.
Yes, the problem was that some processes, needed for updating the project explorer, in Eclipse were frozen and even quitting Eclipse wasn't possible without using Task Manager to destroy the Eclipse-process. Only after restarting my Windows 8 system I was able to continue using Eclipse normally.

I recently upgraded my Eclipse and the workspace stopped working.
So I made a new one, copied all my projects over to it, then imported them.
However, now it shows them as folders instead of the actual packages like it used to:
How can I get the packages back?
Are you sure, you are using the Eclipse perspective Java or Java EE and within one of those perspectives, are using the view Package Explorer ?
Most of the times this happening because the Eclipse view Navigator is used, as show here.
After months of using Eclipse (latest Kepler release) on Ubuntu (13.10), after rebooting from to a sudden loss of power on my laptop, now Eclipse won't let me access java classes within their packages. It simply just shows the packages names but when I click on these the java classes are not showing.
Please note that even though I have several Maven projects working, this happens only on one specific project.
Steps so far:
1) I checked the permissions of all the java files and the directories.
2) Tried updating the project but no luck, also reverted back to my an earlier version (SVN) but didn't help either.
3) I tried deleting .eclipse and re-installing Eclipse and importing my projects, but unfortunately it didn't resolve the issue.
4) I have checked the .classpath file which seems ok.
5) Recursively 'touch' all the files, but still nothing.
I believe that this is a Maven + Eclipse related issue but I have ran out of options here, so I am open to suggestions. Thanks...
Probably it is not a problem of the project but of the workspace metadata. Please create a new workspace and important the project there. Are you able to browser the package explorer there?
Those are empty packages as you know. we need to right click on those packages and create class then you would probably see classes.
In case u still can't see classes then Go to Window->show view->Package explorer
you will be able to see packages along with classes tagged. if you have created any.

I have a plugin in which I have created a perspective. Now I changed the name of the perspective in plugin.xml. It is working fine if I am running from sources. The name of the perspective still the older one when I export the plugin. I am using eclipse juno 4.2
I am completely lost no clue whatsoever. I checked the plugin.xml file in the exported plugin it is having the new name. What is the mistake I am making???
My problem was adding perspectives and views using the plugin.XML, changes didn't take effect because when running plugin projects in development environment eclipse creates a "runtime-(pluginProjectName).application" folder in the parent of the workspace directory.
If you delete this folder eclipse should run with the new changes made to Views and Perspectives structure.
Best of luck.

For some unknown reason the projects that I created in a workspace are no longer listed in the package explorer tab. The actual files of the programs still exist on the flash drive which was the designated workspace. How do I correct this problem so that I can access the projects in this workspace?
Are you in a different workspace? Try File > Switch Workspace or if you are in the right workspace already, you could try File > Import > General > Existing Projects into Workspace and re-import the projects.
Create new project on the menu, then select the button "Create project from existing source" and select your project directory on disk.
If you are working with Android projects, the straight import does not work. The fastest way I've found to deal with this issue is to move (not copy) the projects to a different location, then import them back into the workspace, making sure copying the files into the original workspace.
At this time, the Android eclipse plugin has a bug in it which will rename your projects to the package names, rather than using the "friendly" names you intended for the projects. Since eclipse quite often seems to drop projects in this way, this can lead to a great deal of frustration. If this bug is fixed, or you know of a workaround, I would appreciate hearing about it.
I had a case where my project disappeared from the workspace and when I tried to import the existing project into workspace, Eclipse reported the project was already in the workspace! So I simply created a new project with the same name/location as the folder in which the project was located. This brought the project back to life in my worskpace. This worked in Kepler version of Eclipse.
I found a way to resolve this issue without creating a new project.
My projects disappeared from the Package Explorer view when I was in the Java EE perspective. When I switched to the Java perspective, they reappeared in Package Explorer.
Version: Mars.2 Release (4.5.2)
Build id: 20160218-0600
Not sure what caused this issue out of the blue and how long this solution will hold.
A simple solution that requires deleting the affected projects from your workspace, then importing them again:
Delete the affected projects from your workspace (do not delete from disk)
Open the files. File >> Open Project from File System >> Select location of files >> Select projects to open.
After you import them, it should work.
Try a refresh (F5) of the workspace.
I'm using Eclipse for development because of all the things IntelliJ can't do (e.g. highlight all instances of a variable) and because IntelliJ is dog slow over a remote connection. But because I still don't have Maven integrated completely into Eclipse, I have to switch back to IntelliJ to compile and run my project using Tomcat.
How can I tell IntelliJ to detect all files that have changed on the file system and recompile them? (I don't want to manually open each changed file to get IntelliJ to detect the change.) In Eclipse I would just Refresh the project tree [1]...
Footnotes:
Eclipse has a feature (named "Refresh Using native hooks or polling") which you can enable to automatically detect changes and synchronise the perspective when any underlying changes are detected in the filesystem (see images below). This is quite handy and eliminates the need to manually refresh the project when using build tools - where files/directories get created in the project directory structure.
Is there anything similar for Intellij (explicit setting or otherwise) that eliminates having to click a button to synchronize the view with filesystem changes?
You can use the "synchronize" button (two yellow arrows) or in short Ctrl+Alt+Y
Intellij can highlight variable instances, you just need to enable it .
Further, if you invoke compile project, Intellij will just compile changed files (and hotswap when possible, if you are in debug mode & deploying to e.g. tomcat)
Right click on your Project in the left pane and click on "Synchronize"
You can see the status in the round circling icon at the bottom left of the IDE
I know this question was posted a few years ago, but maybe this info will help someone in the future. I was actually looking into a similar issue, and doing the following worked for me:
Go to Settings > Build, Execution, Deployment > Compiler and make sure "Make project automatically" is checked.
Click File>Synchronize (or) shortcut ctrl+Alt+Y
There is a synchronise button in the tool bar. Click it and it will refresh the project explorer
