I have a folder "JDataCollectionDemo" and I change some variables example int temp from 40 to 50, and now I want to rename this folder as "JDataCollectionDemo50". When I open JDataCollectionDemo50 as a projectfrom File Systems, it will always shows up as "JDataCollectionDemo" under the project explorer.
How can I open it as a "JDataCollectionDemo50" folder under the project explorer? I might "JDataCollectionDemo100" but I always get one "JDataCollectionDemo" folder instead.
The name you see in eclipse isn't the folder name. It is the name which is stored in the .project file (which depending on how you import the project may be the folder name initially).
You can either
remove the project from eclipse rename the folder and the name in the .project file and then re-import the folder
or, easier
select the project in eclipse and press F2 to rename it

I have a Java project in Eclipse IDE for Enterprise Java Developers 2018-12 (4.10.0) built with Maven.
For some reason the folder src/test shows in Project Explorer as a "project folder" (by that I mean a Eclipse project folder, not a file system folder), besides being shown in the project as a source folder as well. That seems unnecessary and anomalous. For example, the same does not happen with src/main, which appears as a source folder only:
If I try to delete the project folder src/test, Eclipse warns me that it contains source folders which will be deleted along with it. I actually tried it anyway once: made a copy of the files, deleted the src/test project folder, and then replaced the files in the disk, but when I do that, the project folder just pops back.
Why is this happening and how can I clean it up?
src with its subfolder test is shown for reasons
There are regular and source folders. For faster access source folders are displayed compacted on the first level instead of in the regular folder tree. In your case, there are five source folders src/main/java, src/main/resources, src/test/java, src/test/resources and - probably by mistake (see below) - src/main which are not shown in the regular folder tree, but on the first level.
In contrast, src and its subfolder test are regular folders and therefore are shown (even if they are empty except for the source folders) in the regular folder tree. They are shown so they can be selected and the right-click menu can be shown containing commands (which might be contributed by additional installed plug-ins) related to selected folders only. Selecting all source folders contained in src is not the same as selecting the src folder, for instance when doing a file search on the selected folders, a .gitignore file in the src folder would otherwise be missed.
src/main should not be a source folder
To have src/main and its subfolder src/main/java as source folders do not make sense since they are nested. In your case, it is a Maven project so you can right-click the project folder and choose Maven > Update Projects... to derive the source vs. regular folders settings from the pom.xml file and overwrite the settings made manually. These settings are stored in the .classpath file. In Maven projects the .classpath file can be derived from the pom.xml file and therefore it is recommende not be shared or versioned.
I have a Project that I have built on Eclipse. I have a property file added in the src directory. The java class file is available in bin, but the property file is not available. Where am I going wrong?
Assuming the type of project is Java Project
Right click on the project and select properties option. Check in the Java build path all files under source folder are included or not and also check if some files are excluded.
In my case property file is being copied to bin folder. See the picture below.
Hierarchy of source folder and bin folder are same in my case.
If project is of type plugin project
Open the Manifest.mf file in Plugin Manifest editor and go to Build tab. Check the property file is selected here if NOT then select the file and check.
Edit:
Troubleshooting steps:
Simply Restart eclipse and completely clean and build the workspace and check.
I read (and sometimes write in) a .txt file in my java project and I'd like it to be copied in the eclipse output folder called "bin".
Can eclipse do it while compiling ?
My project is like :
Project
Bin
blabla.class
...
Src
blabla.java
...
MyFile.txt
Thanks !
I think you need to actually move the text file to a sub-directory - something like "resources" and add that "resources" directory as a source directory to the project - Project/Properties/Java Build Path/Source/Add Folder. That doesn't mean that everything in a source folder has to be compilable.
I don't think that you would have another option, because if you would add the root directory as source folder, eclipse would complain, that it cannot nest source folders. So you need an additional (re-)source folder here.
The solution is :
use Eclipse Classic 4.2.1
click on "add project 'YourProjectName' folder to build path" while creating a new project (in Source tab)
Doing the right Include/Eclude stuff to select which files you want to copy
Suppose I extracted a Java project from a tar archive. How do I add it to Eclipse (Indigo)?
In the past when I have had to so something like this, I simply created a new Eclipse project with the same name and manually copied all the .java files into the proper folder down at workspace/projectName/src/topDomain/companyDomain/packageName.
Is there a better way?
File - Import... - Existing project into workspace.
This supposes that the tar archive contains the whole project, including the .project and .classpath files.
If it doesn't, then either make a new project where you want, and copy the source files, or create a project and specify that its location must be the directory containing the sources folder that you extracted from the tar.
Is there a way in eclipse to make the project's output folder an external folder, instead of a folder located under the project root?
Yes, you can define it as a linked folder.
This this SO answer for more (or this one)
To create a new linked folder select New->Folder, input bin in the folder name: field then click Advanced>>
Click Link to folder in the file system
Click on Variables... to bring up the Select Path Variable dialog.
If this is your first time, or you are linking to a new location select New... and give the variable a sensible name and path.
More precisely, you define your output directory (say 'bin') as a linked folder, then you set that directory as the official output one of your project.
