I have a java based appengine endpoint project in eclipse.
When I generate client library using command line tool.
https://developers.google.com/appengine/docs/java/endpoints/endpoints_tool
I'm getting only source based jar file ('project_name_version'.java-1.18.0-rc-sources.jar). It does not work fine in Android Studio when I add as a Library.
How can I get class based jar client library (google-api-services-'project_name_verison'-1.18.0-rc.jar)?
I tried searching online but no luck yet.
You could always zip up the sources file and use them in Android Studio. However , note that in the build.gradle file, you will have to reference the other dependent JAR files + versions that will be needed by the sources that you have generated in Eclipse via the Generate Cloud Endpoint Library option.
Build your app engine back end with JRE 7. You can change this from windows->preferences->java->installed JREs. You'll find an Add button at the right side of the pane. For more detail refer this Tutorial
This will solve most of your problems.

I'm just trying to add a simple file to my package. After adding the file, I get the below error.
The project was not built since its build path is incomplete. Cannot
find the class file for groovy.lang.GroovyObject. Fix the build path
then try building this project.
Pretty much all posts say to delete the JRE System Library and add it again, do a refresh, clean restart. I did this, but I'm still getting a build path error.
I followed these instructions. Other forums on stack say similar things.

New to Eclipse and Groovy. I just want to follow the tutorial :|
If you have added references to Groovy types, you can add Groovy libraries to your classpath by right-clicking on your project and choosing "Add Groovy Libraries to classpath". This assumes you have Groovy Development Tools installed.
Or you can add "org.codehaus.groovy:groovy-all" through Ivy, Maven or Gradle if you are using one of those for dependency management.
I'm trying to build a web app in Netbeans. In project properties, I have four libraries - JSF2.2, MySQL JDBC Driver, PrimeFaces 5.0 and Java EE Web 7 API Library (all of them embedded in NetBeans, nothing was additionally downloaded). When I was creating the project, I selected JSF2.2 framework and Primefaces.
When I try to build (or clean and build) my project, I get the following error:
Warning: Could not find file E:\My Documents\NetBeansProjects\ConferenceManager\${libs.jsf20.classpath} to copy.
Any ideas?
Solved!
I removed the "default" library and included separate .jar fil that I had downloaded. That solved the problem with JSF, but then the same problem happened with MySQL connector (and I solved it the same way).
I have finished developing a plugin for eclipse, along the way I have been using the self hosting feature of eclipse to test and debug my plugin. However, after exporting the plugin and installing it into my own eclipse host, hardly anything works.
I have JavaFX UI's which wont appear anymore, file's cannot be read due to URI's not being hierarchical, and other parts working very strangely.
I came here to ask why does the plugin work on a self hosted eclipse application while when exported and installed on my current host does not work?
Could it be something to do with other plugins causing conflict ?
Does self-hosting work differently than installations of jars?
The main difference is that your code is packed in to a jar. If you are trying to access files in your plug-in using things like File or FileInputStream or anything else that expects a file these will not work. There are specific Eclipse APIs you must use to access resources in plug-in jars (mainly FileLocator).
Another common mistake is not including everything that is required in the plug-in in the build.properties file. The plug-in jar only includes files listed in this file. When you test locally this requirement is not checked.
I am developing a project on Eclipse Juno using both GWT and GAE.
My original project had all its packages and classes on the same project and it worked fine both on Development Mode and when uploaded to the Google App Engine on the Internet.
Then I created another project (on the same workspace) were I moved the classes that were generic so they could be used on other projects. I have not created a Jar file. Do I have to? I wish I could just keep my generic classes on another project without putting them on a jar file.
After a while I was able to create correct XXX.gwt.xml files on both projects and added the new project to the "Projects" tab of the main project properties (Project >> Properties >> Projects) to make the moved classes visible to the main project. The GWT compiler found those moved classes, translated them into Javascript code and the main project was able to execute them on the client side.
My problem is on the server side. No matter what I try the server part cannot find the moved classes and when trying to execute any of them it comes with the "NoClassDefFoundError" error when running on the Development Mode (I have not tried to upload to the Google App Engine on the Internet yet).
If I comment out all the references to those classes on the server side the error does not show up, but of course I don't have their functionality.

Yes, you'll have to create a jar of the second project, and put it in the WEB-INF/lib folder.
If you can use maven or ant, you can probably set up appengine to compile the other project into a jar and use it as a dependency for the app engine project.
I am building some small Java application to run on Goole AppEngine.
It is not clear to how should I configure eclipse so I'll be able to compile my project but I won't deploy stuff that already exists in on the platform.
(I've tried to read about the subject - here for example - but stil. it is not clear to me).
For example:
The Jersey and the Junit jars - I want them to be uploaded with my code to the cloud in the deployment process.
The AppEngine jars -I need them only for my design time - to be able to write code that is using the platform classes, but I don't want to upload them in the deployment process as they will be available to me by the platform.
Please help to get it right.
I think you need to read a bit from here Google Plugin for Eclipse
And also get the plugin from there, in addition , add the Jersy and the Junit (check first that the API's are on the WillItPlayInJava list) to the build path of the project
