CODENVY: Is it possible to upload a jar file in java project? - codenvy

I am using CODENVY online IDE. I created a new java project .
I need to add new jar file in my class path . How can i add a new jar in class path.

Perhaps, this can help you - http://docs.codenvy.com/user/technology-specific-features/#upload-local-libs
Basically, you need to upload a jar to your project and reference to it from your pom.xml.
If you want to run it like java -cp jar1:jar2, you will have to modify runtime a little bit, and run the commands from the terminal.
It will help if you elaborate on the use case. How would you do it locally?

Why is org-netbeans-modules-java-j2seproject-copylibstask.jar required failed ant build

When doing an ant build (thought jenkins) for a test project, I get the below error. As this test project will be deployed in tomcat why does the build require a netbeans specific module
Obviously I can add the jar file to a path in jenkins and then continue the build, but want to know why it needs a netbeans specific jar?
Is it because the project setup in Netbeans is wrong?
Thanks in advance.
Tony
======Error below here =========
var/lib/jenkins/workspace/DeployTest2/nbproject/build-impl.xml:797: The libs.CopyLibs.classpath property is not set up.
This property must point to
org-netbeans-modules-java-j2seproject-copylibstask.jar file which is part
of NetBeans IDE installation and is usually located at
/java/ant/extra folder.
Either open the project in the IDE and make sure CopyLibs library
exists or setup the property manually. For example like this:
ant -Dlibs.CopyLibs.classpath=a/path/to/org-netbeans-modules-java-j2seproject-copylibstask.jar

How can a jar file be created from a Univocity Parsers snapshot?

I would like to use the Univocity Parsers new functionality that is present in the 2.0.0-SNAPSHOT.
I'm using IntelliJ, and am not using Maven, and currently have the univocity-parsers-1.5.6.jar present in project library, and would like to replace it with a jar created from the 2.0.0-SNAPSHOT.
How can a jar file be created from a Univocity Parsers snapshot?
Any help would be greatly appreciated.
You can just download the jar from maven central:
https://oss.sonatype.org/content/repositories/snapshots/com/univocity/univocity-parsers/2.0.0-SNAPSHOT
A new SNAPSHOT jar will be generated every time relevant features / bugfixes are applied.
If you want to build from the source code, run mvn install using the command line or from IntelliJ itself.

How to Open an Ant project (Nutch Source) at Intellij Idea?

I want to open Nutch 2.1 source file (http://www.eu.apache.org/dist/nutch/2.1/) at Intellij IDEA. Here is an explanation of how to open it at Eclipse: http://wiki.apache.org/nutch/RunNutchInEclipse
However I am not familiar with Ant (I use Maven) and when I open that source file many classes are not known by Intellij.
i.e.:
org.apache.hadoop.mapreduce.JobContext
org.apache.gora.mapreduce.GoraMapper
How can I add them to library or what should I do?
I finally figure out how to do it. Now our team can dev nutch in IntellIJ
The process we do
Get nutch source from apache.org
wget http://www.eu.apache.org/dist/nutch/2.3/apache-nutch-2.3-src.tar.gz
Import nutch source in intellij
Get Dependencies by Ant
Run ant runtime
Run ant test
Import dependencies into Intellij
File > Project Structures
Library > Ivy
Click to Plus button
Select all libraries in apache-nutch-2.3/build/lib
Now we have a project with nutch source and all dependencies
I think, you should use ant build for nutch project. Because, pom.xml is problematical for nutch. If you want to use it anyway maven, you check maven dependency in pom.xml .
I think, the problem can be solved with the following:
You create new project via idea and add nutch source. Idea is not
supported ivy ant project. You can install ivy plugin for idea, I
suppose, Idea12 does not support it.
or
You can create ant project for nutch via eclipse and then save
project. Then open the project on idea via eclipse classpath.
or
You can configure classpath. If you use ant build, you should add jars : File->ProjectStructure as follows:
Create a library
Attach Files
Then, if you use ant build, select jars from NUTCH_HOME/build/lib/* after build.
If you use maven build, select jars from ~/.m2/* (MAVEN_REPO)
Although Intellij supports running ant scripts directly through the IDE via the ant plugin, the Intellij editor will not figure out the classpath using your build.xml file by itself.This will result in the editor showing the code littered with errors.
Unfortunately the only solution I found to this is to add all the jars manually.You can get all the jars needed by building the ant project using the ant jar command.
So these are the steps you need to follow :->
1.Run ant jar command in the root of your program
2.Copy all the jars created inside the build folder(they will not be directly inside build folder.I had to go from build->ivy->lib->{project name})
3.Paste these jars to a new folder created somewhere outside the directory
4.Go to File->Project Structure->Libraries. Press the + button.
5.Select all the copied jars and press ok to any prompts which appear.
6.Press finish and wait for indexing to complete.Any dependency errors in the editor should resolve now.
Note: Since you are manually adding jars, you would need to keep them in sync if you change your build.xml file for any dependency change.
It seems that dependencies are managed using Ivy (see the ivy folder in the sources archives), so you could try to install the Ivy plugin, which would allow you to fix your classpath issues.

Grails can't find classes in jars

I have an app in Grails that uses a .java to manage paypal MassPay feature. Like many .java, it needs some jars that enclose the classes that jar uses. Ok, i import that jars and the errors in the .java dissapears. But now, when I try to run the app, i receive 25 messages like this:
myapproute/grails-app/controllers/com/mycompany/widget/MassPay.java:3: package com.paypal.sdk.profiles does not exist
import com.paypal.sdk.profiles.APIProfile;
That file in the MassPay.java does not throw any error, since i imported the jar where that class is enclosed. But it doesn't allow me to run the project.
Any help? thanks.
Im using Eclipse, not NetBeans (i have read that there is a bug in Netbeans)
Adding JARs to the Eclipse project build path is not sufficient to make them visible to Grails. You need to either put them in the application's lib directory and run grails compile --refresh-dependencies or (better) if the JARs are available in a Maven-compatible repository simply declare your dependencies in BuildConfig.groovy and let Grails download the JARs itself.
Run this - it will work
grails clean

Blackberry 5.0 - Add reference to a Java Library Project

It seems to me that what I'm trying to achieve is incredibly simple, yet is becoming incredibly painful.
I have ProjectA which is a BlackBerry Application project. I have ProjectB which is a Java library project. I want to refer to ProjectB from ProjectA. I can add a reference but when I run ProjectA, it doesn't work. I have source code for both the projects and both are compiled using Java compiler 1.4
I have tried multiple things but everything fails for some reason:
1. pre-verify.exe on ProjectB
It fails with an error "JAR file creation failed with error -1" I can see that the cod and jar files have been created but when add the jar file to ProjectA and run it, it doesn't work. Not sure if I need to add the .cod file.
2. Create new BlackBerry Library Project and reference it in ProjectA
I create a new project ProjectC and then add the jar of ProjectB to it. Then I add a reference to ProjectC in ProjectA. But I cant import classes from ProjectB
Pls suggest a way out.
I'm using Eclipse Plug-in and relying on Eclipse's build capabilities
Figured out answer myself. Publishing here in case someone stumbles upon this. Here are the steps:
Create your library and export as JAR (or download the 3rd party JAR)
Run preverify.exe on the JAR
preverify.exe -verbose -classpath "C:/Program Files/Research In Motion/BlackBerry JDE 5.0.0/lib/net_rim_api.jar" jarname.jar
If you are lucky, you won't run into any issues and you will be done. But I wasn't lucky enough. I got the below error
Error: No such file or directory. JAR file creation failed with error -1
There are two possible causes of this:
jar.exe is not added to your PATH. If so, add it (found in your JAVA
installation directory) to PATH
cvfm or -cfm option on jar.exe fails to execute. I'm not aware of the reason but the way to fix this is to use -cf option, point to the .class files but don't use the manifest file. here is an
example:
"C:\Program Files\Java\jdk1.6.0_26\bin\jar.exe" -cf "output\json-1.0.jar" tmp12996/
tmp12996 contains the preverified .class files.
You may run into different issues other than the one I've listed above.
Once jar is created from above step, make sure that it's structure is as you anticipate. One way to check is to rename the .jar to .zip, unzip it and then check it. If it is not as you need, you can change the structure and then repack it (I wouldn't do any major changes though)
Then add this newly built jar to your BlackBerry application as a reference i.e. add to Java Build Path in your eclipse and Check it in Order and Export window.
That's it! You are good to go! Run you app!
You may face error indicating that the module contains verification errors when you try to run in the simulator. One possible cause of this issue is that your library (the original JAR) contains APIs that are not compatible with J2ME or BB JRE. You may not get a compiler error when you build your library independently as it is compiled against Java 1.4 (or whatever your version is). Best to figure the issue out is to move all your code into your BB App project and then build it. That will tell you all the issues upfront. You make the changes as required and then move the code back to the library. If you don't have source code for the library you are using (like a 3rd party library), you may be out of luck! Also remember that there could be other issues than what I've hit upon and solved.
I'm documenting this at length as it has taken an awful amount of time for me to figure all this out; and to say the least, was most frustrating!
I found another solution. If you get error -1 while preverifying your JAR file, just run your library application once. Because if you don't run the application, the deliverables folder will be empty. Make sure this folder is not empty.
