I'am using NetBeans to write a java application that would allow me to get the zip file of a GitHub user repository. In order to do that, I imported an external jar library, jcabi library, into the netbeans project that let me communicate with the GitHub API.
How I imported: right-click on the project -> properties -> libraries -> Add JAR/Folder
Then I start coding: I tried different constructors for the Github class (the root for communicating with the whole library), but always the same error.
I also tried with another .jar library: kohsuke -> same error.
And if it is not enought, I also tried with eclipse -> same error.
Now, I don't know what the problem could be:
Library importation? (When I write The Github class, netbeans shows me the possibility to import the class, so I don't think this could be the problem, but still...)
My usage of the Github constructor (Probably)
something else?
First make sure you download this jar file: jcabi-github-0.23-jar-with-dependencies.jar. It has all the dependencies you need. Which can be found here towards the end of the page.
It is strongly recommended to use RetryWire to avoid accidental I/O exceptions:
This compiled for me:
Github github = new RtGithub(
new RtGithub()
.entry()
.through(RetryWire.class)
);
Sample program:
Github github = new RtGithub(
new RtGithub("yourUsername", "yourPassword")
.entry()
.through(RetryWire.class)
);
Repo repo = github.repos().get(
new Coordinates.Simple("sebenalern/database_project"));
Issues issues = repo.issues();
Issue issue = issues.create("issue title", "issue body");
issue.comments().post("issue comment");
After running the above code it posted an issue in my repo with title as "issue title" the body as "issue body" and a comment as "issue comment"
Hope this helps! Let me know if you need anything clarified or more examples.
Note this code was tested.

Ok I read too many Threads from many people who somewhat have a similar problem but none of them solved my problem so please assist me with my huge "pain in the ass"-problem which I seem to not fully understand.
I'm trying to use the MediaPlayer Class from javafx.scene.media and sadly the media class isn't inherited in the default SDK's since Java 9 I think and I'm using Java Version 12. So naturally I have to add the jafafx.scene.media library (jar-Format) manually which should be the easiest step in the world.
I am able to add it via "Project Structure -> Libraries -> Add Library" and it shows up in my external library menu but none of my classes can import it.
That's my first Java project (I come from C#) and I even asked my proffessor but he didn't have a clue either. I even tried to create a new project and add it but with no success.
(I tried adding the library via Maven-Dependency, too, with no success)
Then I thought that another library could work and I added vlcj (VLC-Player) and at least it does find something to import after going to "Project Structure -> Modules -> Dependencies" and changing the vlcj library from compile to Provided.
But now when importing I get the following error:
Error
I am so confused. And it's even for a school project.
Please give me advice if you have any or tell me if I need to drop more infos.
Much Love

Adding a library is not enough, the library must be also in the module dependencies.
Also, if you are using Java 9+ module system, you have to adjust your module-info.java file for that. Or just delete this file and don't use Java modules for this project for the sake of simplicity.
I'm following one of the play framework tutorials, but I'm getting compile errors whenever I try to use reverse routing. Firstly,
public static Result javascriptRoutes() {
response().setContentType("text/javascript");
return ok(
Routes.javascriptRouter("jsRoutes",
controllers.routes.javascript.Projects.add(),
controllers.routes.javascript.Projects.delete(),
controllers.routes.javascript.Projects.rename(),
controllers.routes.javascript.Projects.addGroup()
)
);
}
where the error shown in intelliJ is 'cannot resolve method javascriptRouter(java.lang.String, ?, ?, ?, ?)'
But also in the a unit test:
#Test
public void notAuthenticated() {
Result result = callAction(
controllers.routes.ref.Application.index(),
fakeRequest()
);
assertEquals(303, status(result));
assertEquals("/login", header("Location", result));
}
where it cannot resolve the index method.
Is this a problem with intelliJ, or am I missing something within play?
For the first part, here is the entry in my routes file:
GET /assets/javascripts/routes controllers.Application.javascriptRoutes()
and my controller, Projects, has got the defined methods.
File -> Project Structure
Select Sources in Right Pane
Add Source folder
target/scala-XXX/classes_managed
target/scala-XXX/src_managed/main
I was running into the same problem and found the solution here: https://github.com/playframework/Play20/issues/969
In short:
Create the directories javascript and ref under the controllers package
Run activator compile and now Intellij should get it // used to be 'play compile'
If you still got the errors try to run activator idea again // used to be 'play compile'*
Pulled from a link provided by #Markus Kittig. Great temporary fix. https://github.com/playframework/playframework/issues/1784#issuecomment-26345523
Synopsis:
Add target/scala-XXX as a managed source and remove the app controllers and views sources flag inside File->Project Structure->Modules->Sources. Then recompile.
Works on IntelliJ Ultimate 12.1.{4|6}. Created the play application with the command line interface and generated a project file using play idea. Used Play 2.2.0.
With IntelliJ 14.1 and Play 2.3.8 nothing of the above worked, but the advice from this mailing list worked. (Almost) blatantly copied:
Locate the target/scala-2.11/src_managed and target/scala-2.11/twirl
directories in the project view, then right click and Mark Directory
As -> Generated Sources (Root).
I bumped the scala version and obviously in newer versions of IntelliJ the Root word has been added. Also, you cannot select this from the Project Structure window, the option is not available. It is possible only through the Project pane in the main window. If it refuses to be marked as Generated Sources, try to unmark thetarget directory (Mark Directory As -> Unmark ).
For people using Play 2.4.x or above, it seems that Play no longer produces reverse routing files for javascript in src_managed et al.
Instead, you need to include scala-2.xx/routes/main directory as Sources.
This question was asked a year ago, but to answer for future queries by other coders, the problem is easily solved by adding a "play.Routes" path like this
public static Result javascriptRoutes() {
response().setContentType("text/javascript");
return ok(
play.Routes.javascriptRouter("jsRoutes",
// Routes for Projects
controllers.routes.javascript.Projects.add(),
controllers.routes.javascript.Projects.delete(),
controllers.routes.javascript.Projects.rename(),
controllers.routes.javascript.Projects.addGroup()
)
);
}
Ensure that you have the proper imports to the class:
import play.mvc.*;
import play.data.*;
I am using Idea 14.1.4 community edition, i managed to remove the index and route not resolved errors by right clicking on the target folder and marking it as not excluded. NB i run my project using the command line i can not find any run configuration in the ide.
I didn't find that folders in my PLay 2.8 build, so as it was a problem with IntelliJ I found an easier solution:

I am attempting to incorporate admob ads in my app. So far I have added the following code
in the onCreate method of my app's main activity...
adView = new AdView(this,AdSize.BANNER,"my code number");
adView.loadAd(new AdRequest());
The program compiles without error but at run time I get the message java.lang.NoClassDefFoundError: com.google.ads.AdView. I have seen a supposed explanation of the problem and the cure here but I could not see how it was applicable to my project because I do not have either a "lib" or "libs" directory within my project.
According to eclipse's SDK manager, I have the most up to date version of everything that I use.
I had a similar problem, but did not have to add the libs folder; I tried, with no success, then removed them afterwards, when I realized that I had just forgotten to export the included Jar archived.
Fix:
Select project settings > Java Build Path, then Order and export.
Here, check the GoogleAdMobAdsSdk-package.
This should solve the NoClassDefFoundError-issue.
Just create manually the "libs" folder, and add your libraries there. By default, they doesn't exist
Project-> Clean
Project settings -> Java Build Path. Open "Order and export" tab.
Check GoogleAdMobsAdsSDK.
It is worked for me.
Was getting this error updating from android 16 to 20.
Solved by going to Java Build Path, Order and Export tab, checked and moved GoogleAdMobAdsSdk just under my source. For some reason that fixed it.
Changing the order back didn't break it. So some setting must have needed to be initialized.
I had this problem, and this problem too:
Multiple dex files define Lcom/google/ads/AdRequest$ErrorCode and Multiple dex files define Lcom/google/ads/AdRequest$ErrorCode
Despite many hours of following all solutions listed the only way I could get my app to work was to use the AdMob banner example here:
https://github.com/googleads/googleads-mobile-ios-examples/tree/master/admob/SmartBannerExample
And re-build my project around it, copying my files in to that project. If you are stuck, try it.
Don't know why it worked, but now it does. Something in my project was very wrong. Now I can carry on with my work. I love Google/Android, but really what a mess!
See this answer Android update 17 seems incompatible with external Jars.
You need to put all jars in libs folder insted of lib.
It's not enough only to add "GoogleAdMobAdsSdk-6.4.1.jar" in Java Build Path,then you should switch to table:Order and export.check the "GoogleAdMobAdsSdk-6.4.1.jar" here.
UPDATE:
Select project settings > Java Build Path, then Order and export.
Here, check the google-play-services.jar.
This should solve the NoClassDefFoundError-issue.
In my case I needed to click on the "Android Private Libraries" on the "Order and Export" Tab
Go to Properties - Java Build Path - Order and Export and check every Checkmark! That did the trick for my project.
While trying the google plus API example from the project site I'm completely stuck with one import:
import com.google.api.client.googleapis.extensions.android2.auth.GoogleAccountManager;
This thing just doesn't seem to exist in the project.
The sample is a read-made Eclipse project I imported, and to be sure I checked if the massive amount of .jar's in the /lib directory are added to the build path. They are, I can see them listed in the Referenced Libraries part in my Eclipse project.
I can find mentions of com.google.api.client.googleapis.extensions.android2.auth but there just doesn't seem to be any GoogleAccountManager class around.
Several possibilities I have come up with, but can't find out which is it, let alone find a solution to them:
I have not set up my project correctly. I doubt it, but completely possible. This would mean that the example has a broken project set-up and/or I managed to not import all libraries?
The class or package or something like that is renamed // named differently. This would mean the example is broken out of the box, and that I still need to find the correct class (and change the import + calling code to that)
Something else :D
The following are the contents of the libs directory as you can also browse on the project page . Notice that it does containt google-http-client-extensions-android2-1.6.0-beta.jar

guava-r09.jar
On the first page is a link to updated Google plus libraries google-plus-java-starter_v5.zip
Updated Link: google-plus-java-starter_v5.zip
It contains android/libs/google-api-client-extensions-android2-1.6.0-beta.jar, which contains GoogleAccountManager class.
As this is an extension it probably needs other jars too.
(summary of comments)
Manually adding /libs/google-api-client-extensions-android2-1.6.0-beta.jar to the build path and verifying that it is in the Referenced Libraries fixes the problem. It is unknown (to me (Nanne)) why this doesn't happen automagically when adding the libraries, but there you are.
Right-click on Project, select Properties->Java Build Path->Order and Export Tab->click on checkbox for “Android Private Libraries”. That worked for me.
I use eclipse to work on an application which was originally created independently of eclipse. As such, the application's directory structure is decidedly not eclipse-friendly.
I want to programmatically generate a project for the application. The .project and .classpath files are easy enough to figure out, and I've learned that projects are stored in the workspace under <workspace>/.metadata/.plugins/org.eclipse.core.resources/.projects
Unfortunately, some of the files under here (particularly .location) seem to be encoded in some kind of binary format. On a hunch I tried to deserialize it using ObjectInputStream - no dice. So it doesn't appear to be a serialized java object.
My question is: is there a way to generate these files automatically?
For the curious, the error I get trying to deserialize the .location file is the following:
java.io.StreamCorruptedException: java.io.StreamCorruptedException: invalid stream header: 40B18B81
Update: My goal here is to be able to replace the New Java Project wizard with a command-line script or program. The reason is the application in question is actually a very large J2EE/weblogic application, which I like to break down into a largish (nearly 20) collection of subprojects. Complicating matters, we use clearcase for SCM and create a new branch for every release. This means I need to recreate these projects for every development view (branch) I create. This happens often enough to automate.
You should be able to accomplish this by writing a small Eclipse plugin. You could even extend it out to being a "headless" RCP app, and pass in the command line arguments you need.
The barebones code to create a project is:
IProgressMonitor progressMonitor = new NullProgressMonitor();
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
IProject project = root.getProject("DesiredProjectName");
project.create(progressMonitor);
project.open(progressMonitor);
Just take a look at the eclipse code for the Import Project wizard to give you a better idea of where to go with it.
Use AntEclipse
It can create eclipse projects from ant.
To create java project you can use JavaCore from org.eclipse.jdt.core.JavaCore. As a sourceProject you can use generic project item, which has been suggested by #James Van Huis
IJavaProject javaSourceProject = JavaCore.create(sourceProject);
