I am trying to follow the instructions here:
http://android-developers.blogspot.ca/2013/01/verifying-back-end-calls-from-android.html
I have decided to download the google-api-java-client library and see if I can instantiate the code on the bottom half of the page referenced above. I have imported libraries in eclipse in my app engine project so that eclipse doesn't complain about anything BUT when I try this:
GoogleIdToken token = GoogleIdToken.parse(mJFactory, tokenString);
eclipse complains with red underlining on 'GoogleIdToken.parse()' and this text
The project was not built since its build path is incomplete. Cannot find the class file for com.google.api.client.auth.jsontoken.JsonWebSignature. Fix the build path then try building this project
and
The type com.google.api.client.auth.jsontoken.JsonWebSignature cannot be resolved. It is indirectly referenced from required .class files
I have gone to this site and have followed the instructions as closely as I can, but the error remains.
http://code.google.com/p/google-api-java-client/wiki/Setup#Download_Library_with_Dependencies
can anyone tell me how to get rid of this error?
see this link:

The jars with version 1.12.0-beta were not working for me, (as described above) but 1.13.2-beta was released and seems to work fine.
BTW, I was willing to try anything, including different versions of eclipse and wiping my eclipse workspace metadata. I even tried older versions of the google api library, which actually worked. I was going to go with 1.9, but I found out the last one (1.13) had some useful options that I wanted to take advantage of. 1.13.2-beta got rid of the eclipse errors for me.

Version 4.5.1 is the last one available from central - http://mvnrepository.com/artifact/org.eclipse.jdt.core.compiler/ecj/4.5.1
Unfortunately there is a nasty bug, which was fixed only in 4.5.2.
I cannot seem to find a binary package anywhere. I tried building it from sources but failed (details below). What is the recommended way to obtain 4.5.2 binary?
I tried https://github.com/eclipse/eclipse.jdt.core but it doesn't have any relevant tags.
I tried building the tag R4_5_2 from https://git.eclipse.org/c/jdt/eclipse.jdt.core.git/tag/?h=R4_5_2
Suprisingly it still has a snapshot version 4.5.2-SNAPSHOT and requires a parent of the same version. I can try building the parent project, but I'd expect it to be already available in some repository etc. Before proceeding I'd like at least to know if this path is going to lead anywhere.
Finally I came across Project Tycho but I think this is only relevant if I'm creating a new plugin.
I've found one here by random googling: http://download.eclipse.org/eclipse/downloads/drops4/R-4.5.2-201602121500/#JDTCORE
However the timestamp is different than what I get in my Eclipse Mars. Here it's 20160212-1500 and in Eclipse I have 20160128-0629
hello i am trying to run java jsp/servlet application using netbeans but i am getting error message it say
C:\Users\isslam\Desktop\jsp2_allfiles\servlet_jsp\netbeans\book_apps\musicStore\nbproject\build-impl.xml:1009 Warning: Could not find file C:\Users\isslam\Desktop\jsp2_allfiles\Program Files\NetBeans 6.0 M9\enterprise4\modules\ext\standard.jar to copy.
BUILD FAILED (total time: 0 seconds)
I downloaded the standard.jar but i am not sure if it is the right one and i added it to the Libraries and still giving me the same error. the path he is giving me is not real path i can not find it in fact it is kind of wrong
I know this question is almost a year old, but I had the same problem and fixed it so I thought I'd chime in.
It looks like you're using Murach's Java Servlets and JSP exercise files, which is what I'm using too. Well, those are kind of old and include some old libraries.
To resolve the issue, open your project in Netbeans. Right click on it and select properties. Select libraries. You should see a JSTL library that is outdated. Remove it from the project. Now add the updated JSTL library by clicking Add Library and selecting the new JSTL library.
I followed this link http://austindw.com/blog/programming/running-intellij-jdk-1-7-scala-2-10-mac-os-x-10-9-mavericks to configure scala in intellij but it says docs are not found.
any ideas why?
UPDATE:
I have checked the directory structure looks like the scala docs is inside doc folder, here is the pic but still it cant find it.
UPDATE:
I copied the files and folders from another api directory but still the same result, intellij couldnt find it.
Here is the image:
When this happened to me it was because the docs were indeed missing. Look inside /usr/local/opt/scala/idea/doc -- is there a scala-devel-docs subdirectory?
My solution was to download the API docs separately, and put them under the existing doc directory of my installation. You need to make sure that you create the hierarchy correctly:
in your case /usr/local/opt/scala/idea/doc/scala-devel-docs/api -- you'll probably need to do some renaming after you extract the doc.
Here's a direct link to your version of the docs.
If you decide to use IDE support to compilation and building, you might attract on yourself any sort of bug and the anger of software development divinities.
Please use a proper build tool to build software, such as Gradle or Sbt. SBT is native to Scala and Gradle can support it easily. Maven also has a Scala plugin.
I have exactly the same problem as in this question: Eclipse: Using "Open Declaration" ... in a Scala project
However, I'm using the latest Scala IDE in version 3.0.2 (I have downloaded the Eclipse bundle from the site), and I would assume such basic functionality works by now, and apparently it's me who have something misconfigured.
I have created a new Scala project. Then I open some standard library class/trait/whatever, let's say scala.util.parsing.combinator.JavaTokenParsers. The source is neatly displayed, but when I try to show class hierarchy, I get the message: The resource is not on the build path of a Java project.
Also, searching for references etc. won't work.
I guess it is a matter of properly configuring the build path? Or maybe I should somehow attach Scala library sources to my project? But I can see the source, so aren't they attached already?
Here is the snapshot of my project configuration:
UPDATE:
By playing a bit with setting/resetting build path stuff, I managed to get rid of pop-up warning but the class hierarchy comes up empty and when searching for references I get only hits from my own sources, nothing from standard library.
In another workspace I also tried randomly adding and removing scala-library jars and got it work almost, but the type hierarchy comes up only with super-classes, without any sub-classes (which renders it quite useless). Searching for references works ok though.
Funny thing, I cannot make it work in my original workspace...
Gotta love Eclipse.
Your build path is not configured properly.
If you take a look under Scala Library[...] you have scala-library.jar we can only see one top-level package scala. There should be numerous other packages besides that. (Ruled Out)
I would recommend you follow these steps
Right-click project, build-path, Java-build-path, Libraries and make sure that the correct library is referenced there.
If it is the one you need, Try to remove this library and add it again, then clean and re-fresh the project. Also try this step in a fresh workspace.(something must have messed up this workspace )
Lastly. Goto the path D:\Eclipse For Scala\configuration\org.eclipse.osgi\bundles\286\1\.cp\lib and verify the sizes of the jars there. There should be 6 jars there and the size of scala-library jar should be around 6.8M. If size is smaller, consider re-downloading
I've written an Eclipse RCP application that runs fine in Eclipse, however, packaging it to be a standalone application has been tricky. I've worked my way though a few class path errors, but now I'm getting a new one.
After running the export wizard and launching my application, it throws a ClassDefError and ClassNotFoundException, specifically it's looking for org.eclipse.ui.plugin.AbstractUIPlugin. I did not find this in my copy of the eclipse SDK, and I downloaded the SDK again to be sure, and still couldn't find it. I found a jar online that supposedly contained the fiel along with some other eclipse packages, however, I then got this:
NoSuchMethodError: org.eclipse.ui.plugin.AbstractUIPlugin: method ()V not found
I figure the problem is more I did something wrong rather than this class is actually missing, but I've gone though all the configurations and I'm sure all the required packages and dependencies are included. Any ideas?
Download and install the new version of adt plugin 21.0.0.
Does your application works when you run from Eclipse? If so then try to open your plugin.xml, go to Runtime and on the bottom right part of the window you should see Classpath. Try adding the required plugins there.
