I have setup intellij to build a working jar file for the project. However, I need to be able to see what command is being used to generate this, so I can build it directly from the command line.
Any ideas?
Many thanks,
Sam
You may try to use Build -> Generate Ant Build from menu. It will create an ant file that will build the project.

I am trying to import the latest Log4j2 source in my eclipse and Eclipse is not detecting it as a project. it says 'No projects are found to import'. Is there a solution for this?
My goal is to make a jar out of this source. Can i do that without the need to importing it on my eclipse(maybe like a command line solution that can make a build for me)?

It's a maven project, so you should import Existing Maven Project

A simple jar command. You can see more at Using JAR Files: The Basics. A basic command example
> jar cf log4j-sources.jar * // the * is for all files in the current directory
Note: this will not build anything. Just put everything into a jar.
If you have maven you can ask maven to generate the Eclipse .project and .classpath files.
From the log4j2 top-level folder, run mvn eclipse:eclipse
Eclipse will now be able to recognize each module as a project.
After this, to import modules in Eclipse, take the following steps for each module:
File > New > Java Project - enter module name (e.g. log4j-api) for Project name, uncheck "Use default location" and click Browse... to navigate to the location of the log4j-api module. Then click Finish on the wizard.
Does Eclipse provide executing some commands or batch calls when exporting to JAR, like Post-build-Event in Visual Studio? I want to create jni4net a jar proxy automatically.
Take a look at using the Ant plugin.
I am working on a specific maven module. I have it imported into eclipse by m2eclipse plugin. The module uses our internal plugin to generate java files from some csv files. During install goal those files are being generated and put to target/generated-sources/folder_name.
Can you tell me how I can import these java files into eclipse so it stops showing me compilation errors saying that 'x' cannot be resolved to a type?
Now every module which uses those files has compilations errors in eclipse, everything works fine when I try to build from command line.
Thanks in advance.
UPDATE: Thanks a lot guys, I was trying similar solution but instead of adding source folder I was trying to add external classes :|
project -> properties -> java build path -> source -> add folder -> (search for target/generated-sources/folder_name, create it if deleted by maven) -> ok
now eclipse will only complain when you'll use mvn clean deleting target folder.
Eclipse refreshes file content on request, so any change made external to eclipse, eclipse doesn't know about that
You can make eclipse to use native hooks to detect external changes
preference > workspace > check refresh using native hooks
and add that directory to source path
You probably need to add the folder of the generated files as a Source folder in the project. Look in the Project Properties > Java Build Path > Source tab and add the folder.
What is the file build.xml?
I was wondering if it is a possibility to import this project in Eclipse or Netbeans using this build.xml. I tried to import the project but I get some errors since one part is created using J2ME and the other J2SE and I guess this file should be the configuration.
build.xml usually is an ant build script.
It contains information necessary to build the project to produce the desired output, be it Javadocs, a compiled project, or a JAR file.
I believe Eclipse has ant built-in, so it should be possible to execute the build.xml by choosing "Run As..." and "Ant Build".
The build.xml file, if it is an ant script, is not used to import the project into an IDE like Eclipse or Netbeans. A build script is used to build the project (or produce some desired output) rather than an mechanism for importing the project into an IDE.
As mentioned by #coobird this is an ant build file. Although IDEs such as Eclipse and Netbeans have ant support built-in, it is also possible to run ant from the command-line and this may be the simplest way to get started if the project has been well created.
See http://ant.apache.org/
for docs.
If you want to try this approach, install ant, cd to the directory with build.xml and issue
ant
Eclipse can be told to build using an Ant script, but you can also use Ant itself.
build.xml file is an Ant(Apache) script.
you can find more information on Ant & build.xml here
In java project build.xml file is used write the ant script.
And from that ant script you can generate war file and can deploy on Tomcat server
So I have this Java project made up of several classes, some external JAR files and an executable Java program. I would like to export the whole code and external JARS to an external directory and to produce a Makefile to build the program with all the dependencies. Is there an automated way to do it?
Thank you

I think I understand the question. Of course if you use an external build system like maven or ant, then we are decoupling the build process from the IDE. (But in some cases the IDE does integrate pretty closely with the build tool.)
But if you want to continue building using eclipse and to generate an ant file one fine day, then there is a tool for that. Its called EBuild. It leverages all the classpath information that eclipse already has and builds an generic ant file out of it.
Do you use maven?
If so this can be easily achieved with maven assembly.
If not, you can use ant to bundle exactly what you need.
When you right-click your project in Eclipse, there is an option called "Export". It can create build.xml for ant for your project.
