My friend sent me a project from his eclipse workspace for me to take a look at, however when I tried to put the folder in my workspace it did nothing. I opened eclipse and nothing was there. So i tried to make my own project and just put the .java and .class files in their respected folders, but it still didn't work. Is there some special way I have to transfer them? I should also mention he has a windows computer and I have a mac if that makes any difference for file types like that. Thanks for the help!
If you can just take the .java files and paste them into your 'src' folder in a new eclipse project, you should have no issues. Just make sure you refresh your project in eclipse(right-click on project folder and click refresh, or click on it and hit f5).
This is what i normally do.
Suppose your eclipse workspace is D:\EclipseWorkspace and your project name is Project1.
Then i would copy Project1 in eclipse workspace on disk to have D:\EclipseWorkspace\Project1.
Then create a new java project in eclipse and when prompted for name provide name as Project1 (exactly same) and say finish. It will import the project automatically. Everything should be up :)

Recently I worked on a project on a mac, using eclipse. When I was done with the project I copied certain .java files and their corresponding .class files onto a USB drive and brought it to my personal computer. When I try to use the import feature on eclipse and import everything, my main method is not recognized by eclipse. It will work if I create a new eclipse "class" by the name I have in the program and copy paste the code. I have many classes so I can not do this for each one. Is there any way for me to change all .java/.class files into files that will be read by the system?
Thanks
An eclipse project contains a lot of meta information. Just open the project directory in a file browser, and have a closer look. There are files like .classpath for example.
When you just copy your source code, you leave all the meta information behind!
You should either copy the complete project directory, or simply use the export task to create a ZIP file of your project. (to later import that in other systems).
There is one other way you can do this. Just create a new project with the SAME EXACT PROJECT NAME that you did at school or wherever. After you create your project, go to your file explorer and navigate to the following place:
<"Directory to work-space">/<"Project Name">/src/
For ex: in Windows, it is Generally:
C:/Users/your_name/workspace/projectName/src
In here, copy all your ".java" files.
Now go to eclipse, right click on your project and hit refresh. You will find all your .java files there. Right-click on your project and hit "Run"->"Run as a Java Project". It should run! hope this helps.
PS: You do not need your class if you are executing it in Eclipse. Eclipse will create its own class files.
I work in an organisation where i am provided with a folder having codes and other things for particular application.
I want to open this folder in eclipse and be able to navigate to all the classes that are used through resources(ctrl + click).
The problem is when I imported the folder the eclipse worked same as that of a notepad. Any changes no error would be shown.
I even added the required jar files for that project.
What should I do? I just need to navigate and check out the classes that are used and declared. Pls Help.
P.S. - I work on Ubuntu Machine.
If you have a java project, you may need to configure the source directory(s).
This can be done by right clicking on your folder -> Build Path -> Use as Source Folder.
Hi i write a Java Swing GUI that includes alot of .jar files.
I have add alot of .jar files to my Buildpath. If now my friend trys to run the programm he got my Buildpath and they are wrong on his pc.
Is there a possible way to set the Buildpath so my friend don't have to set them again?
for example at the moment one buildpath is like this:
home/usr/bonzai/oad/xxx.jar
my programm that is executed is in the folder bonzai. so i want to set the path like this:
./oad/xxx.jar
So the programm knows go into the folder oad, that is in the same folder, then take xxx.jar.
Hope you understand what i want to do :-)

I had this problem with using a project on Windows and Linux.
Go to Window->Preferences->Java->Build Path->Classpath Variables
Click "New", pick a name, like MY_PROJECT, and point to the project folder.
When you include jar files, you do it a different way.
Project Properties->Java Build Path->Libraries (where you add jar files)
To add, click "Add Variable"
Select the MY_PROJECT variable you made and click "Extend". Find the resource and add it to your project.
Now when anyone wants to use your project, they just have to do step 1 and 2. and point the MY_PROJECT classpath variable to where ever the folder is. It can be anywhere. As long as the structure inside is the same, everything works.
This is how I share .project files with GIT. You can clone the project anywhere but everything works.
I had two java projects, one called MyServer and one MyClient
I wanted to merge two, i.e. just have one project called MyServer.
I copied the .class files and the .java files from MyClient's folder on my harddrive and pasted into my MyServer project folder.
But it doesnt show up in eclipse, I tried refreshing , and then restarting eclipse but none of the java files show up. I can still see MyServer's own source files but not MyClients files that I just pasted.
I am sure I am doing something very simple wrong. Even in Project explorer I cant see the source files
:(
Thank you to all for answering.
I used Syam Kumars answer . I deleted the project from eclipse, without deleting contents on disk option , then imported a new project and pointed it to the project folder. Now all the files are visible.
Thx
Try to add it using the eclipse file menu:
Project -> Properties -> Java Build Path -> Libraries -> Add External Class Folder
I have three different projects in my eclipse and yesterday src file became unvisible in one of the projects. Two days ago it was ok and I have no idea how this happened. I can not see src file in project explorer or package explorer.
Project Explorer :
However, if I look with navigator I can see all files in the directories.
Navigator :
I use Eclipse Indigo SR2 and IBM Rational ClearCase for first two project. The other is my local test project.
Do anybody know how can I get back to src file into the project explorer?
Thanks.
Try to right-click on the project and click on refresh.
I had the same problem today, it is because i switch to wrong view model.I suggest you to switch the project explorer to Package Explorer.
Check your Java build path to make sure the src is present. Right click the project and select Build Path -> Configure Build Path. If the src directory is not present in the build path, it will not show up under the Java area as you have shown, but it will be present in the Navigator.
I had the same problem in Neon - src folder had disappeared. One sub-directory in the src folder would show up but no other sub-dir and not the parent src file itself. No matter what I did in the buildpath configuration only the one sub-dir would show up. It looked like some kind of corruption in the settings. None of the above solutions worked for me, including deleting the project and all files, and then re-checking it out.
What did work was switching to an old workspace, importing a project and then switching back to the workspace with the issue. Magically, the project with the problem was again responding to my changes in the buildpath configuration. I'm not sure if I had to do the interim step of importing fromt he old workspace or not - possibly just switching back and forth would have worked but not sure.
Try removing (deleting) the project without removing the files (there is a checkbox that allows you to keep the project files).
Then re-import the project. Not sure if this will solve your problem, but I was facing the same issue and delete->re-import resolved it for me.
I had this problem today, and the issue was that the "src" folder was not correct in the "Source" tab of "Configure Build Path" window. It was there but the path was wrong, so it had a red X. Deleting that entry and re-adding the "src" path (from the project) resulted in putting the "src" folder back into the packages hierarchy.
In my case, this happened because of sharing the workspace between user accounts, the paths to the workspace and the folder beneath were not the same. One user accessed the workspaces locally, the other as a mapped drive, etc.
Fixing this and then standardizing the path to be identical for all who access sit, resolved the underlying problem that caused this issue to surface.
Restart your eclipse work space.
Also change open perspective in eclipse.
