I am a programming student that recently upgraded the hard drive in my laptop through a secondary service. This service was able to save and transfer over most files, but was unable to migrate over specific program files.
When trying to reinstall Eclipse I have encountered some major issues and problems I am looking to hopefully get help with.
The first issue is that through the Eclipse installer, when trying to install eclipse it would try to look for the previously used user file and spew out 100s of error messages when this failed. A workaround to get eclipse actually installed was to change the bundle pools to off.
The second and most major issue is that eclipse does not seem to recognize or have any in build libraries, as it does not even recognize what a string is. I have the JDK and JRE installed but when trying to compile is tells me that java has been installed incorrectly (which would make sense given my hack job of installing it).
Any help would be greatly appreciated. I have never had so much difficulty trying to simply install something.
Try deleting .m2 folder present inside C:/Users/<User Name>/.m2 and then reinstall Eclipse.
I have eclipse and the ADT bundle correctly installed on my home PC, and tried to install it on my laptop so I can work on my projects on the go. However, I either didn't set the java paths correctly, or installed them in the wrong place, because I can't get a default project to load without errors.
I have correctly:
-Installed the ADT bundle and launched eclipse without errors
-Created a workspace
-Correctly Installed both the jre8 and jdk1.8.0_05 in the location C:\Program Files\Java
I am very new to Android development, and I feel like I was lucky to set up the Java dependencies correctly on my home PC, no such luck this time from what the error look like...
However, when I try to make a basic "Hello world" project, I immediately get the following error:
The container 'Android Dependencies' references non existing library 'C:\Users\userName\workspace\appcompat_v7_3\bin\appcompat_v7_3.jar'
I have tried adding the library, by checking build configurations, but I don't understand fully whats going on to correctly solve the problem. Here is my workspace:
And lastly, I tried checking the build configurations to see that the libraries are, in fact, missing. Or something like that. I am not sure if I should just try to reinstall java and the jdk.
Build configuration:
Anyway, I'm not sure what I deleted, misplaced, uninstalled, or didn't install, but if anyone could point me to a solution I would be very grateful. If anyone has any other questions on my setup I will try and be as thorough as possible. Thank you!
In my experience I have had issues like this if not running eclipse as Administrator. Make sure that you aren't being blocked here.
EDIT: Please note Chris Stratton's concers regarding running an IDE as Administrator, as seen in the comments below.
EDIT 2: In my more recent experience, I have noticed that if I installed the SDK by copying and pasting the contents of the downloaded, compressed, folder to a destination rather than extracting it first, I would be required to run as Administrator. If this is the case, delete the SDK that you copied out of the compressed folder and simply extract the contents of the downloaded compressed folder. I am running Windows 7 so it is likely that this applies to all Windows 7 and 8 OS's.
In another case, I have also seen issues like this if the JRE is installed second rather than first. In this case, a reinstall of the SDK is probably all that is required.
Hi i've been trying to install the library on Thinking in Java book 4th edition and i hit a very thick brick wall. I've done everything that the guide from the website told me to do and i still can't get the library to work. From what i've read it seems that the problem is from the build.xml files. having no xml knowledge I am clueless about how I have to modify it in order for it to work. In both cmd and eclipse I am getting these error
c:\TIJ4\code\build.xml
Build Failed
c:\TIJ4\code\build.xml:59:J2SE5 required
Can anyone tell me what I should do ?
I am using eclipse if there is a simpler solution by using eclipse rather than ant please help me out. It's been a week now and I still can't make it work.
The important thing to do is to realize that your ant file has a specific java requirement.
Something to try that might fix this very easily : I believe you can remove any references to a specific JDK, and if you have a reasonably up to date JDK, the build will succeed.
The definete fix : Look into the exact (line 59) of your build file, and try to satisfy the java version that line requires. Java is generally backwords compatible -- something designed to run in J2SE5 should run in the latest JDK. Its not terribly difficult to update your JDK (just google for instructions on your OS).
The most common mistake I see is that people who have the java run time installed believe they also have the Java SDK as well.
Does this "install the library" means you want to look at the code and run them in your eclipse? If so I can share my experience with you.
First run the Eclipse.py script; this will add package info to the source code
Create a new Java project in Eclipse, and then just copy all the source code folders to the src source folder in eclipse, these folders will then be recognized as Java packages.
You should be able to run the classes with a main function.
You can also configure which java version to use for this project in Eclipse build path. 1.5 or higher will work.
I recently became interested in Minecraft modding, so I downloaded MCP (Minecraft Coder Pack) and Eclipse. After running decompile.bat, I opened Eclipse using the workspace provided by MCP. At first I was given a list of errors related to missing libraries, but I easily fixed that by fixing their paths. Then I continued following the video tutorial I was using and pressed "Run" and selected "Client" as the project to run. Eclipse gave me the following error:
Must specify a URI scheme:MCP_LOC/jars
I have been Googling this for the past 20 minutes with no success. What is wrong, and how do I fix it?
I can probably still program mods for Minecraft and even recompile them with MCP, but it will be difficult to test them. Does anyone know what's wrong?
NEVER START IN ECLIPSE
Try This vid for 1.7.3
Its a nice little series about minecraft modding.

Android Packaging Problem
I've never worked with Java or eclipse before, I'm following this introductory guide and all searches via google return no helpful results. I'm guessing the problem is I have built Android stuff with eclipse properly but I have no idea, I followed this guide to the letter and everything went as it explains it should.
Any ideas what caused this problem, or is it specific to the guide? If so I'll post on their help page.
I have tried doing project -> source -> clean up, but that didn't fix anything.
Edit:
I went to Project -> Android tools -> Dex bytecode and it reported:
DexDump: missing classex.dex for project. Please compile first.
So I guess that's my problem! Not sure how to solve though.
Go to Project -> Clean
It will rebuilt workspace and fix the errors if any.
As I said, I had the same problem so I tried all the different versions and
then I stopped filling in the SDK-version number
and finally it did not complain anymore about the wrapper.
After that it was totally fine to write the SDK-version when I created new projects.
Hope it works out for you too.
Had the same problem (running on Windows 7). I resolved it by running Eclipse with Administrator privileges.
try to run eclipse under administrator permission. Problem may be resolve.
I think you installed the SDK in "Program Files" folder . So for do something inside, must have administrator permission.
One thing that may help is to create a new test Android project.
In Eclipse, select File → New → Android Project.
Set the project name to "Test3", check Android 2.3 for the build target, type "com.example.android.apps.test3" for the package name, and type "Test3Activity" in the "Create Activity:" text box. The form should look like:
Click Finish.
Expand the entry for "Test3" in the Package Explorer. Navigate to res/values/strings.xml. Double click on the entry for strings.xml:
Set the text content of the string element having name "app_name" to "Test3":
Right click on "Test3" in the Package Explorer and select Run As → Android Application. The emulator should open and after a long while, you should see:
If these steps do not work, then you probably have an error in your installation.
Try it out and let me know.
I had the same problem earlier today. Google was largely unhelpful.
I fixed it by removing the project from eclipse, then re-importing it.
According to this bug report the problem is caused by upgrading to version 9 of the SDK.
Had the same HelloWorld problem with Ubuntu 64 Lucid / Eclipse 3.5.2 from Ubuntu repository. Restarting Eclipse did the trick, though I notice it still fusses about API level requirement when HelloWorld is run.
Running it as Administrator has solved this issue for me..
Had the same problem - occurred after I tried downloading Android platform v2.3.3 (was using 3.1 and 3.2 earlier) and it interrupted in the middle - restarted eclipse and cleaned all projects and rebuilt and the problem went away
At what point in this tutorial/guide are you running into this problem and did you make sure to include your package information in each file or ie com.something.somethingelse at the top of your class or classes?
Perhaps a registry error or maybe even a problem with activity implementation.
Please post your code if this did not start you in the right direction.
Here are a few things to check:
Make sure you have the latest version oF Eclipse (Helios)
Make sure that you have the Android SDK plug-in for Eclipse.
Now if you have done that... Make sure that any classes you add (Each screen you view on Android is a class and is called an Activity) are in your androidmanifext.xml file See http://wrenbjor.com/2011/01/12/the-androidmanifest-xml-file/ for help on understanding this process.
otherwise make sure there are no red x's in your code or it wont work.
If you still have problems post some code and we can try to help.
Had the exact same problem the other night. Upgraded to Helios (3.6) and it went away, quite possibly as a side-effect.
Under windows 7, rather than run eclipse as an admin, change the permissions on the eclipse folder so the creator/owner has full control, and do the same with the folder the android SDK is installed into.
I had installed Eclipse using the files provided by Windows' native ZIP extractor. I deleted the files and took them from 7-Zip instead. Now the error is gone. So maybe using another ZIP extraction tool will help.
Recently got this when failing upgrade using adb-manager with eclipse open (win32). As eclipse was open, upgrade failed. Then returning to my project this problem occured.
Was solved by closing eclipse, restart as administrator and cleaned project.
I had the same problem but I resolved it using following steps(using eclipse helios and windows XP ) :-
Right click on eclipse.exe.
click on Run As...
Uncheck the checkbox before "protect my computer from unauthorized activity".
And it is running for me as expected !
hope it will also run for you.
