I have a Maven module, that depends on various other Maven dependencies by which I am accessing through my jython code.
I am now done, and I would like to compile the project as a .jar, or even just run it without compiling, but I have no clue where to start.
Does anyone have any idea how I can run some .py files that accesses some Java libraries in other packages?
Also, how can I compile it as a .jar file when all is done and good?
Thanks!
Compiling and integrating python
Use the jython-compile-maven-plugin. It allows you to deploy a standalone project that includes jython with libraries.
For demonstration of this plugin, see the demo project and its source code. It shows how to
launch a python console -- look at AbstractInitJython and InitJython on how to launch a python/jython console, how to execute python code snippets, and how to run a python script.
include python libraries -- the plugin also downloads and bundles python libraries (using easy_install) in the package phase, and adds them to the jar. The resulting jar can have all the libraries of the project, all pom dependencies and all the python libraries requested. The demo project shows this with the "nose" python library (see the pom file).
Testing python / jython code
The python-test-maven-plugin allows you to run your python tests alongside the normal junit tests. The demo project (look at the source at source code) shows the use of standard python unit tests (with nose) and BDD (behaviour testing) with the lettuce-clone freshen.
The sourceforge umbrella project is http://mavenjython.sourceforge.net/
Unlike maven-jython-plugin, they don't use the outdated jythonc compiler.
I am now done, and I would like to compile the project as a .jar,
It looks like there is a maven-jython-plugin allowing to compile jython source files to Java class files.
I've kinda figured out my answer to this. I shouldn't have tried to compile it, but instead wrap the python code with Java: http://jythonpodcast.hostjava.net/jythonbook/en/1.0/JythonAndJavaIntegration.html#using-jython-within-java-applications
The compiler portion of jython, jythonc, is deprecated as of 2.5 -- http://wiki.python.org/jython/ReplaceJythonc -- a replacement is in the works.

i created a Javafx project using JDK 8 and when i tried to export it to a runnable .jar file, i got surprised that it doesn't run using CMD, and gives the following error :
"Javafx compenents are missing"
while it works perfectly during the compiling time(using the IDE) when i accessed the .jar files, i found it has just .class files (that i made), and the needed library files that haven't been exported (i made sure to select the "extract need library files extract required libraries into generated jar" option in Eclipse), is there a reason behind of this? and a way to solve it? thanks in advance
Ps: i tried this using Eclipse and Intellij IDE
I just wanna mention once again that I'm using JDK 8 where it has JavaFX library inside of it.
Did you try this?
There are detailed instructions on how to configure your IDE to run JavaFX with newer OpenJDKs (which do not come with JFX components in it).
It also explains how to create a new JavaFX Maven project from archetype, with all the necessary plugins to easily build your application while including the minimal Java components for it (using jlink).
This will ensure that anybody using your application will have those components.
I would like to try to build Kotlin/Native project with dependencies on some library.
As documentation explains, I need to create def file (which I was already created) and run cinterop tool.
However, I wasn't able to find this tool on my Mac and curious how this could be installed.
Can you please give me some advice?
I strongly advise you to use Gradle + Kotlin MPP plugin. Not only it will provide cinterop support, but it will ease further development, testing, and multiplatform support. It works on any OS, of course.
If you need an example, here is the official one for the cURL library: https://github.com/JetBrains/kotlin-native/blob/master/samples/libcurl/build.gradle.kts. Note the cinterops block under compilations["main"].
The nice thing about Kotlin MPP plugin is that it actually allows you to play with the Kotlin/Native tools directly. It will download the tools specifically for your platform automatically on the first run and place them in ~/.konan directory. So if you really want to use cinterop tool from CLI you'll be able to find it there: ~/.konan/kotlin-native-macos-1.3.61/bin/cinterop. klib and kotlinc are there as well.
I have installed Intellij IDEA Version 2017.1.4 and installed the Fortran plugin. However, I don't see an option of starting a Fortran project even after restarting IntelliJ. I see the plugin has been successfully installed though.
Is there a simple hello-world fortran example with Intellij?
Thank you
No, you can't create a Fortran project in Intellij IDEA. You can use cmake to build you project and import such project in CLion. Here you can find some information about compiling Fortran project with CMake. Also several example projects can be easily found in the Internet.
General idea behind this is that IDE is not a build tool, so you are building your project with build tools and we are doing our best to support build tool that you're using. For now from all JetBrains IDEs only CLion supports build tool that is capable of compiling Fortran project (CMake). In the future CLion will support other build tools capable of doing this (make for example).
JetBrains just released a new Fortran plugin you may be interested in. I tried it in IntelliJ 15 and it did not allow me to create a new Fortran project. I have NOT tried it in CLion yet.
I have a project that's using the Play framework, and the corporate standard is that all projects should be built by Hudson. However, I cannot find out how to do this, as Hudson does not follow any Java standards, and requires the framework installed at the computer it runs on. I have tried to build the project with Maven (if I had managed this, adding it to Hudson should be quite simple), but I have failed to make it work. I tried the Play Maven module, but Maven claims it does not find the external repo that is listed (http://nexus.infin-it.fr/content/groups/public). This might be because I am behind a firewall. I also tried the recipe listed here, but the local maven build fails because it is unable to find org.playframework:play:1.1:jar.
Has anyone done this and can provide a howto?
It can be done without installing the Play framework on the Hudson server, but it is quite complicated:
Put the play libraries (play.jar and its dependencies) in a Maven repository
Create a pom.xml for your project, configured with:
theses libraries as dependencies
your project specific dependencies (project lib directory)
the java sources folder of your project (in the maven-compiler-plugin): "app"
If your project is simple (no module dependencies), this pom allows you to build the play project java sources using Maven.
If your project has module dependencies, you will have to add the dependencies jar in your pom dependencies.
To do that, you will have to create jar files from the modules if they don't have packaged jars (to get the "CRUD" class of the CRUD module for example).
You can find some help on this page I wrote :
http://blog.infin-it.fr/2010/12/15/play-framework-integration-continue-retour-dexperience/
Even if it's in French, I put my Ant stuff and the Play's pom I wrote.
At work we managed to integrate our Play applications with Bamboo.
It should not be difficult with my files.
Just looked at the repository, that you linked (http://nexus.infin-it.fr/content/groups/public). And guess what, I found the play-1.1.jar. However, the artifact ID is: org.play:play:1.1:jar and not org.playframework
In theory, you could put the full Play zip on your build or in in your repository, and then use Hudson to kick off an Ant script to download Play to the Hudson agent, unzip it, and then run commands on it. It's a little clunky, but it should work.
I am developing an Eclipse plugin and I use maven to coordinate my source structure. In order to compile the plugin I use the tycho extension for maven. However, I was wondering how to execute unitests.
I want to use the surefire plugin for testing as I additionally use a sonar server for source code quality management. Unitests are applyed if I use eclipse-test-plugin as package target. However, I want to make use of the default surefire plugin for applying unitests.
Now I figured out that the src/test/java that contains my unittest packages is read and compiled correctly but written into the wrong output folder. I need to have the tests in target/test-classes. However they are compiled to target/classes.
As I am new to Eclipse plugin development and maven I could not find out how to write the tests to the correct output folder. I've already tried adding and and changing the build.properties of the eclipse-plugin project. It works also fine for other projects that aren't plugin projects and do not make use of tycho.
Any help appreciated.
Regards,
Florian
Unlike standard maven projects, the convention for eclipse plugins/OSGi bundles is to have tests reside in separate projects. This is because there is no such thing as a maven dependency scope "test" in OSGi.
Thus keeping your tests inside the same project as your code under test would force you to mix up test code/dependencies an productive code/dependencies.
As you mentioned, Tycho provides a separate maven packaging type "eclipse-test-plugin" which you should use for dedicated test plugins/fragments. See https://docs.sonatype.org/display/TYCHO/PackagingTypes
There is no support in Tycho for plain unit tests residing in the same project.
