Java Eclipse folder with git - java

I've been working on a Java package using eclipse and have been using git for version control. I accidentally git rm'd a file, committed and pushed it.
In order to revert the effects, I did a checkout of the deleted files from a previous commit, did another commit and pushed it back. Now I have my files back.
However, those files do not show up in the package in Eclipse -- what could I be doing wrong?

I sometimes get inconsistencies between Eclipse and Git, to solve this I usually just refresh the Eclipse project. I could be more complex than this, but eliminate the simplest solution first.

Maven build for git committed code

Is there any build tool like maven,gradle support to build only staged/committed code not to include unstaged/untracked file.
Basically while development some scenarios arise in middle I want to check what committed package vs uncommitted one.Though I can achieve two different directory but such flexibility in any build tool will help a lot.
Ex: Consider I have one maven project I modified and committed & pushed the code to GIT Repo.Later I started my further development.When I do build, it builds including all the files but I wanted to know If there is any way I can skip the unstaged/untracked files in maven pom.xml to build only committed files.Any plugin like that which helps to achieve this or any other build tools.
I think git stash comes in handy for this:
Use git stash when you want to record the current state of the working directory and the index, but want to go back to a clean working directory. The command saves your local modifications away and reverts the working directory to match the HEAD commit.
Something I use and find very convenient is particular Source Code Management plugin for Jenkins, see complete list of similar here. In my case I use Git plugin, which provides Refspec configuration property. I put there either committed or uncommitted changes' refspec. The build uses source code built until the change pointed in the refspec. Due to my understanding - this is exactly what you need.
P.S. I also build with maven, even though this doesn't matter for this case.

How to fix corrupted Eclipse Indigo JEE?

I installed following plugins in eclipse indigo in following order to start spring development
Spring Tools Suite
M2E (Maven)
after these two installations, it was giving error
jira connector not installed, so I installed the following plugin.
Atlassian Jira Connector
After installing Jira Connector, Eclipse Started showing the following error :
Uninstalled Jira Connector. Still Showing these Problems.
Any help would be appreciated.
Eclipse has major structural problems with uninstalls, which aren't really fixed even the latest luna. But don't worry, there are a lot of workarounds.
What you can do now and in similar situations:
1.
If you can even uninstall something, you won't get back its previous state before the install.
Because of it I use Eclipse normally with a trick: I store my main Eclipse install directory in a git repository, and so I can always switch back with a single command. But it is only a trick.
2.
There is a big chance, that only your workspace directory is damaged, and not your Eclipse. In this case you can solve this problem by reinitializing your workspace: make a backup, delete everything, recreate your workspace directory and finally import again your projects.
(For similar reasons it is also an useful trick to save your workspace metadata in a git repository as well.)
3.
In Eclipse, the menu items are created by modules. If an eclipse module is installed, it creates the changes in its internal configurations which create the menu items.
After a restart, Eclipse tries to restore your gui, and thus re-open its panels. But if a module uninstall is also happened, then its panels aren't restorable, resulting exactly your problem.
So, simply close the bad panels and try to reopen them. Sometimes it also works.
In short: recreate your workspace, it will probably help. And next time, use Eclipse with some good and frequent backup (I suggest git).

Sudden weird errors on a project

Today I came to work, happy. But when I opened my Eclipse, I saw that one of my projects has errors.It's weird because it shows that it has errors only in the window bar, and not in the Navigator. I don't have any Java errors, this is a valid project that was fine all the time:
Some of the errors on the error log of Eclipse:
JavaBuilder handling ImageBuilderInternalException while building: SP_Procedure
Cannot connect to VM
File <SomeFile> has been skipped, problem while reading ('Resource is out of sync with the file system')
Unhandled event loop exception
Internal error
When I run an application from this project, I get a warning message but when I proceed, it works fine, but still. It's very disturbing and I'm not sure if it's harmless.
I tried to:
Restart Eclipse
Restart my machine
Clean projects and recompiling them.
Refresh projects
Pray
Nothing helped. What could be the problem? (I'm using Indigo Service Release 2)
The following nuclear option has desperation written all over it. But I have been where the OP has been with the Juno version of Eclipse.
Run a "Synchronize with Repository" and save all of your local updates to a different directory.
Delete the project. (Check the box to delete the contents on disk. Scary step, but that's OK, because you saved it in a different directory in the previous step, right?)
Read in a fresh project from the repository. It builds happily at this point.
Integrate your local updates.
Keep on praying.
Looks that one unused JAR was deleted, but for some reason, I didn't get errors in any file, even in the files that imports this JAR! So what I did was restoring this JAR, delete unused imports and deleted the JAR again.
I've found this error after two days of navigating on this project on each file.. This is weird that Eclipse didn't recognize that1 this is an error, and throw many unrelated errors such as:
Cannot connect to VM
File has been skipped, problem while reading ('Resource is out of sync with the file system')
Unhandled event loop exception
Is this a bug in Eclipse? (All errors and warnings are enabled!)
1 As seen in the image in the question..
A class from the list of imports for the file seems to have moved out or the jar file containing the class is missing.
Expand the imports section and check if you find some classes that are missing but have been imported.
Though it is a pain, sometimes the easiest solution is to back up all your projects (either in a repository or somewhere else on your computer) then uninstall and reinstall eclipse. No it's not fun, but it should reset eclipse so everything works again. The downfall though is that you have to reconfigure eclipse to any special settings you had/reinatall any extra functionality currently installed (eg. android add-on) and reconnect to any repositories you have. While punting isn't fun, it can be effective... I hope you don't have to resort to this though.
I have went through that problem a lot of times, and tried everything you tried. Rebuild, recompile, refresh, remove and add JDK, remove and reinstall Eclipse... nothing worked
The only thing I concluded is that the workspace metadata was corrupted.
What I did (every time it happened) was
Create an empty workspace
Import -> existing projects into worskpace
Mark the "copy projects" (else it will only link them)
Wait for the copy, and start working with the new workspace
If you work with SCM systems (Git, SVN, etc), making a full checkout will do the trick too, but the worskpace import will let you retrieve those changes you didn't get to commit (if any).
It's a little painful if you have somethings already set (like JDK names, servers, etc), but then I realized it was faster than keep searching how to fix the workspace
Regards!
PS : I've been working with Kepler lately, and everything works fine till now
Click Window -> Show View -> Other -> General -> Problems
This view will show you what is wrong.
Did you, by any chance, update your virtual machine outside of Eclipse? I can't help but feel that we're both missing a finer detail here. I just keep seeing "cannot connect to VM" and thinking that it's a major clue.
Have you tried running anything from the terminal? Does it work there?
If so, do you know where your current edition of Java is located? Is Eclipse looking somewhere else?
Is this exclusive to one project? Do you use any additional libraries to the JDK?
Maybe try this for Resource is out of sync with the file system error:
Right click project in Eclipse Package Explorer
Close Project.
Right click project in Eclipse Package Explorer
Open Project.
Other things not mentioned:
project properties > java build path, see if any of those tabs got changed, local file got moved? read/write permissions on some file you are linking to?
project properties > java compiler, see if workplace settings have changed? maybe under errors/warnings, you can systematically set them to 'ignore' until the error goes away to determine what type of error it is?
maybe update some of the eclipse plugins?
I saw something like this happening for a number of reasons. Mainly because of validation in files other Java source code. See if you are validating XML for instance.
Right click your project and chose Properties (Alt+Enter) and Validation to see the related configuration.
As for the danger, I lived with those marks for ages and nothing wrong ever happened.

IntelliJ and SVN: "no changes detected" upon commit

I'm trying to share a project between my desktop and laptop using Subversion. The project has 3 modules. I've imported the project folder into a repository in a shared folder that my laptop can access over the network.
I checked the project out on my laptop and then tried to open the project. None of the modules are visible, only the project's .iml file, as in the screenshot below.
I notice that the .iml file has a line for "content url", which refers to a location on my desktop. Maybe this is the problem. What can I do about it? Do I have to create a new project on the laptop and import the modules - so there would be 2 different top level .iml files, one for the desktop and one for the laptop? Am I going about this the wrong way?
UPDATE: The problem seems to be with committing. When I make a change in a file, save, and hit Commit Changes, I get a popup saying "No changes detected". This is the same on both laptop and desktop, and meant that I downloaded the wrong version onto my laptop before. I deleted the repository and created a new one, and my project works on my laptop now, but I can't commit changes from within IntelliJ (only with TortoiseSVN via file manager). Also, when I imported my project into version control from my desktop computer, the working copy wasn't put under version control. So I can't update from my desktop unless I check it out to a different folder.
I think there is something wrong with the SVN plugin with this version of IntelliJ (10.5.1). Does anyone else have problems with committing changes?
RESOLUTION I needed to
1) Update Settings | Version Control to map Subversion to the working directory
2) Import into Version Control
3) Check it out again
It may possibly have been caused by the fact that the modules were originally standalone projects which were in separate repositories. Whatever the cause, IntelliJ's "No changes detected" dialog isn't the most helpful.
VCS -> Refresh File Status solved this for me, when Intellij suddenly stopped noticing changes.
Please refer to the FAQ.
As for the content root, make sure that it's located under the project root or module root, in this case the path will be stored relatively to the project/modile root inside the iml file. If the fixed system specific path is used in the iml, such module will not work on other systems.
UPDATE:
Make an explicit mapping between the actual working directory and Subversion in Settings | Version Control dialog. If you are using the default placeholder and your project files are not under the checkout root, it could be the case.
After performing the initial import you need to do a checkout in order to use version control in IDEA.
Sometimes doing VCS -> Refresh File Status works for me.
Other times, it does nothing.
A solution is to
COPY all your file contents to clipboard / external notepad (for backup)
Choose Rollback on the file which needs updating. Now it is up-to-date with the server and does not contain your new changes.
Edit file again (checkout), and PASTE your original file contents.
Attempt to commit changes. It should detect them now.
I just ran into this today- checked out an existing project and had to update the SVN scheme from 1.6 (I think) to 1.8. That seemed to make Subversion not recognize that it was wrong it its belief- even though I could DIFF and see changes relative to the latest repository version- that "No Changes Detected."
I got so fed up that I shut down Intellij...on a whim I reopened it, and the file in question appeared blue...hmmm...yep, now it detected the changes.
I had the same issue it seems it may have been caused by having a file with the same name in two different GIT-repositories.
I was able to fix it by opening File -> Settings -> Version Control and then un-assigning and re-assigning GIT as the VCS of the two directories which both had the file. First the directory in which there was no changes in the file then the other active one which did have changes (but which did not detect them before).
I got into the similar issue today and I tried VCS -> Refresh File Status, but it didn't help me. When i looked at Version Control->Subversion Working Copies Information, i found an svn error The working copy at /home/project is too old to work with svn client 1.9.4. First i ran svn upgrade and then doing VCS -> Refresh File Status resolved my issue and i was able to commit my changes.
None of the other solutions here helped me.
Ended up checking out the entire repository again, copied all the sub folders over to the newly checked out folder and submitted the changes.
Deleted the old folder and renamed the new folder to the old folders name.

Eclipse Commiting to SVN

I'm trying to commit my changes to my SVN repo, by clicking on the file, team, commit, but then in the Console in eclipse, it says
commit -m "" /Users/admin/Documents/workspace/Challenge5-Ghostomatic/GhostList.java
Skipped
And it does that for all the files, even though the local version has changes that the SVN doesnt have. How do I fix this?
This "skipped" thing comes from the fact that somewhere, somehow, you corrupted the two trees of files between the repository and your local copy. It is most likely that the issue comes from the fact that you did not merge the two repositories, your local copy, and the subversion copy, before making changes to your file, or adding a file.
Following this tutorial all the way through might help. It's very short and should clear up all your errors.
http://www.eclipse.org/subversive/documentation/gettingStarted/aboutSubversive/mylyn.php
If you checked out your project using subclipse or the built in subversion client then it should be a local working copy. You should verify that as kraftan suggested.
If you have somehow corrupted your local copy you can always check out the head revision to a new project area and copy your locally updated files over again. I would suggest backing up your working area before mucking around too much.
What happens if you run a compare with latest from repository?
