My Eclipse stoped showing errors in project explorer window. Currently in I ask Eclipse run class I got message:
Error in Workspace
Errors exist in required project(s)
Prog
Proceed with lounch?
And I have no possibility to check where are these errors are. How to fix this problem?
Open the Problems view. It will display all the compile time errors & warning in your open Applications. To open that view follow the steps:
Go to Window: Show View: Other: General: Problems.
Also to view the errors in Project Explorer, try cleaning the project, as suggested by Vimal Bera.

Using eclipse to build a java project, I hit the Build Project button, there is no discerneable feedback/output whatsoever?
How can I tell that a build, happend and succeeded?
I have looked that in the filesystem the Project directory has indeed a /bin directories with compiled *.class files, so I now that something was build, but I look for a way to have eclipse give me that information.
How to configure eclipse to give output (i.e. to the console, status bar, if necessary message popupbox) about that some building happend.
As such you should get a popup window (shown in my last screenshot) showing the progress of your build, but in case if you are not getting then you can follow below steps to get "Progress" view of the Eclipse which shows progress of everything in the Eclipse.
And then build the project:
And you should get the progress information
As an aside: how to identify if Eclipse project has error? - If you project has build errors (it could be Java build problems, or JS or XML issues) then in the "Project Explorer" you will see a cross-mark-inside-red-square against that project, see a sample below:
Update: Another possibility to double check - make sure you are not running progress bars in the background, to verify that go to Window --> Preferences --> General and make sure "Always run in background" is NOT checked.

I am working on a project in Eclipse. Usually, whenever there are compilation errors in a particular file, the file name in the Package Explorer view is shown with a red box and a cross. This helps to find files with compilation errors easily.However, in one particular project, I have some files with compilation problems, but those are not shown with red in the package explorer. Only when I open the files in eclipse, do I see the compilation errors. Also, this behavior is happening only in one project. Other projects are showing compilation errors properly in the package view. Any idea why this is happening ?
Is there an error red cross on the project?
Check the Problems view. (Window -> Show View -> Problems)
It could be that there is a build path error, or another error at the project level.
Often I've found that "cleaning" the project helps show those errors in the package explorer. Go to Project -> Clean... and select the projects you want to recompile.
Also it might even be easier to use the error view to jump directly to the source of your error without the lengthy way using the package explorer.
I am writing the code in eclipse. In my project explorer there is an error(red x mark) displayed on my project name. But there are no errors in the other sub folders.Can any one say where can i find those errors.? What is to be done to find the problem. Thanks in advance
The errors from Eclipse are usually avaiable from Error Log View
Window -> Show View -> Erro Log View
Also you can try to clean and rebuild the project.
One possible cause for such thing is build path issues. Go to your project build path and look at the list of included jars: check if you have any jar marked with the same red x. Also, check the eclipse "Problems" tab.
Go to the 'Problems' tab (hit Ctrl-3, then start typing Problems). It will give a description of what's wrong.
I'm building an Android app.
I worked today on my app, and suddenly I saw that all the projects in the workspace are marked with an error. I don't know what caused it, and I can't find explanation of the error anywhere.
I'm using Helios with Windows 7. I even tried downloading Eclipse again but it didn't help.
Today I tried to integrate Facebook with my app. Their tutorial required me to try to get a hesh key from a keystore. In the process I added an Environment Variable named JAVA_HOME, and pointed it to the JDK.
I don't know if it's the cause of my problem, but I think it might be related.
I really don't know what to do.
Thanks!
Try this. In eclipse, go to Project --> Clean --> Select "clean all projects". This should rebuild all projects.
Try cleaning your android project. I get problems with Eclipse sometime, and if I clean the project, it fixes it.
Find the "Problems" view. That will give you more details. Post the description of the problems, we can get more information.
click Window -> Show View -> Problems
Typically, the problem is with a resource you've recently added to your project (drawable, assets, raw, etc.)
Some things to check are:
Invalid XML files
Invalid 9-patch images (outer 1-pixel border must be full black or transparent)
Typically, just start by removing a resource, then cleaning your project (Project > Clean). If the errors go away, that resource is your problem. If not, continue this process until the error DOES go away. Start with the most recent resources you've added, naturally.
i solved error or all project showing errors this way.... close eclipse.
then Right Click on eclipse shortcut-->open file location-->open command widows there and type "eclipse.exe -clean" eclipse the starts..and in my case errors were gone...hope it helps
I've created a Java project from existing source with an Ant build script in Eclipse. I cannot run my project because Eclipse tells me that there is at least one error in it.
Now, I know that the project runs fine on the command line, so I suspect an Eclipse configuration error.
As far as I can tell, the only feedback that I have from Eclipse is
a little red X on my project in the Package Explorer window
(source: gregmattes.com)
and dialog window when I try to run the project says there are errors in the project
(source: gregmattes.com)
This is all wonderful, but what is the error?
Is there a "show me the next error" button somewhere?
In the past, on other Eclipse projects, I've notice other little red X's on folders containing source files with errors, the little red X's appear on the source files as well. I scanned (manually) through all of the source files and I haven't found any other red X's (again, where is the "next error" button?).
If I select the "Proceed" button I am greeted with a java.lang.NoClassDefFoundError for my main class, which makes me suspect a classpath issue. I've checked the classpath, and I'm fairly certain that it's correct. Is there a way to see the exact jvm command line that Eclipse is invoking? I realize that it might be invoking the JVM programmatically, and not on a "real" command line. In any case, is there a way, other than the run configuration dialog, to see what is actually happening when I hit the "Proceed" button?
The errors are shown in the Problems view. If it is not opened, go to:
Window > Show View > Problems
Also accessible with the keyboard shortcut Alt+Shift+Q,X
Selecing Window -> Show View -> Problems will open the Problems view, that should have a list of all problems, their location and nature (it can be configured to show only project- or file-local problems, so you may also have to click on the project). Most likely you have a config error in your project, e.g. a reference to a JAR library that cannot be found.

if you get that kind of an error which shows a red cross on the project folder just refresh that project right clicking on it i was having the same problem as above so try and see...
