I'am working on a project which requires adding multiple jar files to intelij idea as a plugin but only one jar files gets added as a plugin to the IDE.

I'm trying to find more information on how eclipse handles Running a project.
I want to understand it more because I have an issue I'm currently having where apache-poi .jar files which have been included into the classpath of my project will work properly when the project is ran through eclipse, but will not be detected when going to the same projects folder and running the main jar file to start the program.
It gives me the error: java.lang.NoClassDefFoundError: org/apache/poi/ss/usermodel/Cell (although sometimes instead of Cell, it's Sheet)
What could I consult to understand what is going on here, and possibly solve this issue?
Your NoClassDefFoundError indicates that the library was not available while running the jar.
This depends upon how you are exporting your project into the jar file.
If you're using eclipse to do so, you can:
Export->Java->Runnable Jar to create a jar that includes its dependencies
Make sure to check Package required libraries into generated JAR.
This will make all your jars (in build path including apache-poi.jar) as a part of the final jar.
It runs from eclipse because libraries are on the build path of the eclipse which makes them available in the classpath.
My in tension is to create a plugin at at the run time using java code.First a created executable jar using the java.util.jar.JarOutputStream and used javax.tools.JavaCompiler for compiling the classes. And I was able to execute the jar from command line properly.
Then I tried to create a pluign by including the plugin.xml file in the jar package and compiled the classes by using the above packages and plugin is created with out any errors.
But I was using an extension point for the plugin and it is not detecting while I am putting my plugin in the eclipse product.
Then I exported it by using eclispe export option and it is working properly for me. I unzipped both the jar created programtically and by using eclispe and the contents are same.
How can I solve this issue?
I am using SHERLOCK-ACTION-BAR in my project
I successfully am able to run the project using the library refered in eclipse
What i am not able to do::
I am trying to add JAR file to libs in my project and run it
(removing the reference i made earlier to my previous library)
So i copied the JAR from Libs of Sherlock library project and added
to my project
When i do this i am not able to import the class file from JAR
Where can i download the correct JAR
You can add JAR from Project - Properties.
Then go to Java Build Path and add your JAR or External JAR.
Clean your project after add it ;)
I have a plain Java project (not a plugin project) which I want to add to a classpath of a eclipse plugin which I am developing. But in web projects I can add that project as a build path and it works fine. But I tried same thing in eclipse plugin, I am able to compile successfully, but at run time I am getting java.lang.ClassNotFoundException.
I know OSGi quite well and I know how to add OSGi into an classpath (using export-packages) but what I want is to add Standard, non-osgi project into an classpath, so that I wont' get runtime errors. Is there anyway I can achieve this?
I can export project as a jar file or make it as a plugin project and it would work fine. But that's not my option currently because, still that API is in pre-alpha stage, and there would be lot of changes going on. So I am trying to avoid pain of exporting it as jar file everytime. Is there any option for me other than this?
I have a similar situation: I want non-OSGi Maven dependencies integrated into the classpath of my plugin. I succeeded with a roundabout solution, which I think is the best I could get.
I have a build step outside of Eclipse where I copy the class files of the dependency into the plugin's lib folder. The lib folder is specified in MANIFEST.MF as an entry in Bundle-ClassPath and (here comes the hack) as a source folder in build.properties. That was the only way to make the plugin work both when launched from within Eclipse and when exported.
New to NetBeans dev here. When I first created my project and began compiling, I noticed that NetBeans had automatically created a dist/ directory under my project root and was creating an Executable JAR in that directory.
I've now been developing for several weeks, and added many resource files to my project, including a system log file, an embedded SQLite database, and several properties files. These are files that my program (a Swing app) needs to read/write from at runtime in order to function correctly.
I just noticed this morning that the Executable JAR in my dist/ directory is several weeks old, and that compiling my project doesn't update it. I am wondering if that's because there are now all these new resource files and NetBeans doesn't know how/where to package them for the automatically-created Executable JAR.
Does this mean that I'll have to tweak the build.xml myself? Or is there a NetBeans dialog I can get to where I can specify where to pacakge everything? And if NetBeans should be doing this automatically, what could be the reason that it stopped creating the JAR for me, and what can I do to force this functionality again?
I went into Project Properties >> Packaging and made sure that the JAR file directory was still dist/MyProgram.jar and that the checkbox Build JAR after compiling was still checked, so obviously something else is either breaking the build or messing with NB.
Thanks for any tips!
If "Compile on Save" is enabled, then your .jar file will only be generated when you do a "Clean & Build" (Just "Build" is not available when "Compile on Save" is enabled)
You need to Clean and Build within netbeans to update the file within your /dist directory.
I use Netbeans 7.0 and this solution works for me.
