Java project from existing ant build file doesn't appear as in version control

I have a repository in which I have a simple ant project (only the src directory and the build.xml file). I did a checkout of this project in a local copy. Then I opened Eclipse, created a "Java Project from existing Ant build file" and it worked fine. I can build, clean, run, generate javadocs, etc. However, my problem is that the source files in the packages, as well as the project itself, doesn't appear to be under version control in Eclipse. I can work with it fine from Cygwin, but not from the GUI.
The odd thing is that I have several regular Java projects, on the same repository which are synced fine by Eclipse, so it's not a version issue.
When I created the projects that work, I had to go to Team->Share Project... and Eclipse told me that they were already under version control and updated its configuration. However, in this current case, this isn't working. Any suggestion please?
EDIT:
I'm using svn 1.8.
UPDATE: I tried creating a regular Java project, and this time the version control looks fine, so it appears it's an issue related only to Java Project from Existing Ant build file.

The problem is that Eclipse doesn't know your project is using Subversion as a version control tool. You did a checkout outside of Eclipse, then you set up Eclipse as if this was a non-version controlled project.
To get Eclipse to recognize the project as under Subversion, you need to let Eclipse know. This means you should have said "File->New->Project, and select SVN->Checkout Project from SVN in the new project wizard. Then, Eclipse would have checked the project out in Subversion for you, and Eclipse would understand this project is in Subversion.
Unfortunately, I am not quite familiar enough with Eclipse to know how to tell Eclipse that the current project is really under version control. The best I could come up with was:
Right-click on the project and select Team->Share
Say this is a Subversion project you want to share.
Select the Repository to use
Select the folder where you want this project, and select the current folder.
You get the following warning:
Warning: The specified folder already exists in the repository. If you continue, that folder will be checked out to the existing location. Do you want to continue?
Your project will now be "checked out" over your current project. Everything should be okay because the files you have either match what is in Subversion or are modified versions of what is in Subversion.
You will be then asked to use the Synchronized view. Check "Yes", and then switch back to the Java view. Eclipse will now know your project is under Subversion and everything should work fine.

NetBeans 7.3 freeform Java project - how to add a 3d party library to the project.xml?

I have a freeform Java project (with my own build.xml file) in NetBeans 7.3 and I need to add a 3d party library jar to this project. I know how to do that to build and run, but when editing I still see warnings about "cannot find symbol...". When I open the project properties and click on "Java Sources Classpath" I see the "Add JAR/Folder" button as inactive (why? I don't know, I couldn't find a way to change that). I know that I can edit the project "nbproject/project.xml" file manually, but I need an exact syntax.
Could you please give me a piece of advice, how to add a library jar into the "nbproject/project.xml" file for a freeform NetBeans project?

OK, I can answer my own question now - thanks to the NetBeans plugin, called "Freeform Project Extras", which provides a number of new templates and some documentation about the "project.xml" layout. So, the "project.xml" should contain the following XML element (in its simplest form):
<java-data xmlns="http://www.netbeans.org/ns/freeform-project-java/2">
<compilation-unit>
<package-root>${basedir}</package-root>
<classpath mode="compile">abc.jar:xyz.jar</classpath>
</compilation-unit>
</java-data>
It's essential to refer to the second version of the XML schema here.

How to organize jar files in a libraries folder in Eclipse?

I have a Java Project in Eclipse, and a Java Dynamic Web Project in Eclipse. In the former, all the jar files are shown individually under the top-level project folder. In the latter, the jar files are under a Libraries folder and the navigation is more convenient.
Is it possible to organize them in the same way in the Java Project also? If so, how?
Update: It is the Project Explorer View. For the Java Project, I see: "my_project_name" with the arrow expanded to point downwards, then I see: "package_icon src/main/java" and below that "package_icon src/main/resources" and then 20 jar files one below the other: "jar_icon activation-1.1.jar", ...
For the Java Dynamic Web Project I see: "my_project_name" as above, then I see: "JAX-WS Web Services" (unexpanded), then "Deployment Descriptor" (unexpanded), then "Java Resources" which I have expandeded, so I see the components of it below, of which the first is: "package_icon src/main/java", then below it, "package_icon src/main/resources", then below it "libraries_icon Libraries" instead of 20 jars! I have the option of expanding Libraries if I really need to see the 20 jars.

The only option I found to make things prettier in Eclipse Kepler is to:
In the Project Explorer window there is a down arrow in the upper right corner. Select that and then Customize View.
Select 'Libraries from external' and then OK.
Kind of cheesy...
EDIT: Of course I had to go and do some more digging...and it looks like I'll have to try this and see how it works.

Similar to M Miller's answer (but for Juno), click Show 'Referenced Libraries' Node in the dropdown of the Package Explorer window:
I'm using:
Eclipse IDE for Java Developers
Version: Juno Release
Build id: 20120614-1722

I noticed this "feature" on Eclipse Juno (latest version), when you have a jar file added to the build path it is not shown as a single file on the project.
Try removing one of the jars from the build path to see if it shows up again.
I couldn't find how to turn it off though.
BTW... the project layout for your "Java Project" is more akin to a "Maven Project", which is a bit more powerful.

You should change into the Package Explorer by Window > show View. It will display all the referenced libraries in a Referenced Libraries folder.

How do I reference libraries in NetBeans?

I have a Java Web Services project that was created in an older version of NetBeans, and I haven't accessed it in many months, so my paths and installed libraries are different.
When I try to open the project, I get a "Resolve Reference Problems" dialog, and two Reference Problems are listed:
"metro" library could not be found
"JAX-WS-ENDORSED" library could not be found
I have a fresh installation of JDK 6 Update 25 with NetBeans 7.0, and am running Windows 7.
What steps can I take to solve this? I don't even know where to start, as every approach I've taken so far hasn't gotten me anywhere.
Note: JAX-WS-ENDORSED does not appear in my Libraries listing, so I can't remove it. Something hidden is referencing it. How would I find this?

I just came across this issue and found some help from http://netbeans.org/bugzilla/show_bug.cgi?id=187145. Apparently, Netbeans will create the JAX-WS-ENDORSED library when a new web service is created. So go to File > New File, choose Web Service > Web Service Client and fill in dummy values (this can be done in a throwaway project). This client can then be removed, and Netbeans will have created the library with the following classpath entries:
java/modules/ext/jaxws22/api/jaxws-api.jar
ide/modules/ext/jaxb/api/jaxb-api.jar
These are relative to your Netbeans install directory (on OS X will be located in Contents/Resources/Netbeans within the .app). Alternatively, you could create the library manually using the entries above.
This only needs to be done once, as the library will be added to Netbeans Global Libraries list.

The best solution is to edit project.properties file and replace below piece of code.
Original property: endorsed.classpath=\${libs.JAX-WS-ENDORSED.classpath}
Replace with: endorsed.classpath=\${lib.JAX-WS 2.2.classpath}
In older versions of Netbeans there is JAX-WS-ENDORSED library in libs location.
Newer versions of Netbeans having JAX-WS 2.2 library in lib folder
** ALL THE BEST **

If it is still needed, I had the same situation when opened a netbeans 6.9 project in netbeans 7. There is no way to resolve the 'jaxb-endorsed' (in my case was jaxb and not jaxws) reference using the libraries window.
I found a endorsed.classpath property in the nbproject/project.properties file.
I still not sure what is its purpose, but in this property I found the bad reference to jaxb-endorsed.classpath, so I deleted, closed netbeans and opened again, and the reference problem has gone.
I already have Jaxb 2.2 library added to my project, so it is working good with the modification I did to the project.properties.
I hope it helps.

I had a similar problem : DO NOT DELETE THE JAX-WS-ENDORSED - remind me to downvote. I had to go to the imported project > resolve reference
problems dialogue > delete the references from there which were pointing to the old NB folders - pic :
and then create the throwaway web service as suggested by William Scott and then add the newly created jars :

Netbeans maintains a set of libraries, which are simply a convenient way to manage groups of related jar files. Start by clicking Tools > Libraries. You will see the library manager window.
You will see the options to add your own libraries if you have jar files downloaded. If you do not see the library that you are looking for you can download them and add them your self. Once the library exist in Netbeans you can go to the Project Explorer window and right click on the Libraries tab of your project. Select Add Library and you will have the chance to add the library that you added in the library manager.

You may want to right click on your project, go to properties -> Libraries.
Remove the JAX-WS-ENDORSED library, and try using JAX-WS 2.2
Also remove metro and try adding METRO 2.0
That may solve your problem.
You may also want to right-click on your web service references and select
Edit Web Service Attributes
Then on wsimport Options tab see if xendorsed is set to true.
UPDATE
You may need to close netbeans and then open it again, and it may work. I was having a problem similar and I just did that and it worked.
The only difference, and it may not be needed, is that I also added the JAXB 2.2 library, but that was because I was trying to solve a compilation error.

I had same problem and Fix it by install soap webservice and and resful webservice in netbeans plugin

I fix it:
unistall netbeans.
delete HOME/.netbeans and HOME/.nbi
then install netbeans again

Old thread, different and effective solution... I just moved some projects from one system to another and got this error. With NetBeans v7.3+, go to Tools>Plugins, Available Plugins, then search for "SOAP". You should see "SOAP Web Services". On loading this library you'll get the JAX-WS-ENDORSED library. Restart NetBeans and you should be able to get a Clean Build.
Loading this package brings in a number of other libraries. On restarting the IDE you may get a notification that other packages now have available updates.

Do the following ( BTW in my case its NetBeans 6.9.1 )
1 Why this appeared now ?
Because i tried to open project on other pc with fresh copy of net bean
2 How the problem looks like ?
Jar Lib Not Found for JAX-WS-ENDORSED
3 Why it was needed at the first place and what its used for?
Well i have a webservice on same server/domain e.g localhost , so of course
it will work if i removed the web service from the folder in sources but i need it
4 What to do?
Try to add dummy any online free web service in form wsdl
like Some test web service or search for any other one
This is the source of my public free to use wsdl
5 What then ?
Just add it please
Now what ?
Wait for scanning project stuff it should be ok
you can re check from library properties of project
or see that there is no red/ or resolve references problem
in project properties
So what happened exactly?
Note: JAX-WS-ENDORSED it will be added automatically to your libraries
same methodology can solve other problems as well

Converting an Eclipse Java project to a Google AppEngine one

I have a project with a large amount of pre-processing. I have written this part and would now like to convert the project to a GAE project.
I have enabled the GAE support in Project->Properties and have some functionality but when I want to testrun the app I get a "Web application archive directory does not exist."
Is there a way to automatically generate the missing folders and files or do I have to do that manually?
I do not want to copy my classes into a newly created project since that would mean loosing all my version control.

I think that with the GAE plugin for Eclipse, you can create a GAE app skeleton. You just have then to move your old project files into this project, and you're done.
For just conversion, I don't know if it's possible, if the structure of your app is completely different from the GAE structure.
As for the error you have, it seems that your app lacks a WEB-INF directory that any webapp needs to run.

I am using GAE Eclipse Plugin 1.2.1 and Eclipse 3.4.2 and I have tried the same operation and have been unsuccessful so far. I believe the eclipse plugin is hardcoded to look for the various components at specific locations. (The right approach would have been to configure the GAE plugin to look for the all the WEB-APP components at other locations than the default.) I would think that given these versions, converting an eclipse project directly wouldn't be possible.
A possible solution, given this constraint, would be create a new GAE project and copy all your existing code into that structure without altering the folders already created by the GAE plugin.

Don't know if this will work for Java -> GAE project conversion, but I've had luck doing something similiar, converting General -> Java projects using the following steps:
Close your project.
Open your project file (which is located in your root directory of the appropriate project) called .project with your default editor. Search for:
<natures>
</natures>
and change it to
<natures>
<nature>org.eclipse.jdt.core.javanature</nature>
</natures>
Store the changed file.
Open the project again - now it's a java project.
Of course you'll need to create a new GAE project and then look inside its .project file to get the correct element contents.
I found the above steps googling around, so I can't unfortunately credit the original source of the above instructions.

You CAN convert your existing eclipse projects to GAE projects. All you need to do is right-click the project and choose settings. Then choose Google settings and tick the "use Google App Engine SDK" option.
Using Google Plugin for Eclipse with existing projects

Not sure about the whole GAE specific stuff, but you can copy your old projects contents:
Create new GAE-Project
Close it
Use a file manager outside eclipse to copy all your old projects contents into the new project. Make sure, you include the ".svn" folder, it may be invisible in the explorer/nautilus/whatever. You should also think about leaving the .project file of the new project alone, as it may contain GAE specific configuration.
Open the project in Eclipse again
Right click project -> Team -> Share project -> Select SVN
Your old project URL should be already there, leave the radio button with "Use project settings" checked.
The project connects back to the old repository location, and in sync view you should see the new files as outgoing.

To complete #Marks response, you should add this line to your .project file:
<nature>com.google.appengine.eclipse.core.gaeNature</nature>
