How to compile eclipse project using command line in linux? [duplicate]

I want to compile my Eclipse project using the command line.

Can anyone provide instructions?

This SO Question has an answer that explains how to do it.

I just want to add that it is a bad idea from a couple of respects:

• If you wire this into your build scripts, you are tying your project to the Eclipse IDE. If someone else who prefers (say) NetBeans has to take over the project, you are making life hard for them. Even more so if this is an open source project.
• You are potentially make life difficult for yourself too. For instance, suppose that you needed to do an emergency rebuild on a machine that didn’t have Eclipse installed, and you couldn’t install it for some reason.
• If you are using Maven (or Ant) in your project, then running the build tool directly from the command line will be faster. And in the case of Maven , running the build tool directly will (in my experience) give you more consistent builds than using embedded Maven.

If you are not familiar with Maven or Ant already, you should learn about them rather than trying to use an IDE as a batch build tool.

Personally, I’d be using maven to set up my project and then using it to compile. Once your project is set up in maven, mvn eclipse:eclipse to generate your eclipse project and mvn package to generate your jar.

What’s the best way to run a small/medium java program from the command line?

Coming from a c++/make background, I’m used to doing something like this to build and run small/medium programs:

However, with java/ant I’m finding I have to do something like this:

ant java -ea -cp build/ foobar 

Typing out java -ea -cp build/ foobar every time I want to test my program is pretty annoying, I’d much rather be able to do something simple like ./foobar .

I came up with two possible solutions to this problem, but neither seems very good. The first is to just have the compile target create a file called run :

#!/bin/bash java -ea -cp build/ foobar 

And then just use ./run to run the program, however this seems to go against ant’s cross-platform nature, and also just seems like a bit of a hack.

The second option is to create a run target, for example:

This method also works, and seems a bit cleaner, but is incredibly slow! For example:

$ time ant run Buildfile: /somepath/build.xml init: compile: run: [java] /* program output */ BUILD SUCCESSFUL Total time: 1 second real 0m2.683s user 0m2.548s sys 0m0.136s 

The above is almost 20 times slower (!) than this:

$ time ./run /* program output */ real 0m0.143s user 0m0.124s sys 0m0.020s 

So is there a better/more standard way of running a small/medium java program from the command line? Or should I just use one of the methods I posted here?

It seems to me you want to build/run during development phase.

If so, then get an Eclipse and use it to debug/run, it’s the most effective way of developping under java.

• Ant is used for packaging phase
• shell is used for running program, and you would write one per environment (Linux/Windows/Mac OS)

Compile Multiple Java Files Using a Single Command in Java, To compile the Java file, we used the below command. This command will create a .class file in the current directory. Java. javaCopy javac Hello

Compile and run test with JUnit in command line on a single Java class

I have a simple problem I don’t know how to solve!

I have a single Java file User.java :

import java.util.Vector; public class User < private String name; private Vectorfriends; public User(String name) < this.name = name; this.friends = new Vector<>(); > public void addFriend(User newfriend) < friends.add(newfriend); >public boolean isFriendsWith(User friend) < return friends.indexOf(friend) != -1; >> 

and I have a simple test class UserTest.java beside this class:

import static org.junit.Assert.assertEquals; import org.junit.Test; public class UserTest < @Test public void evaluatesExpression() < User user = new User("foo"); User user2 = new User("bar"); user.addFriend(user2); assertEquals(true, user.isFriendsWith(user2)); >> 

I want to run this test class for the User class. I’m not using IDEs like IntelliJ or Eclipse, so I want to compile the test from linux command line, but this command:

javac -cp .:"/usr/share/java/junit.jar" UserTest.java 

gives me the following errors:

UserTest.java:1: error: package org.junit does not exist import static org.junit.Assert.assertEquals; ^ UserTest.java:1: error: static import only from classes and interfaces import static org.junit.Assert.assertEquals; ^ UserTest.java:2: error: package org.junit does not exist import org.junit.Test; ^ UserTest.java:6: error: cannot find symbol @Test ^ symbol: class Test location: class UserTest UserTest.java:11: error: cannot find symbol assertEquals(true, user.isFriendsWith(user2)); ^ symbol: method assertEquals(boolean,boolean) location: class UserTest 5 errors 

Note: everything I have seen on Stackoverflow is about testing a single file in a project or building and testing with gradle and . but I don’t know much about Java and I don’t need to know much, I just need to know the simplest way to create and run a test for a single Java class.

Note2: I have installed junit with apt install junit and it installed junit-3-8-2 version.

Note3: I have problems when trying to compile my test class, I haven’t even reached the stage where I can run the tests!

After quite a lot of trial and error in the comments section, the root cause was an old JUnit 3.8.2 dependency. The 3.x releases used a different namespace that was changed in 4.x to org.junit .

Therefore the classes where not found while compiling the test.

To debug such issues unzipping the jar with unzip on Linux can be helpful.

How to run Eclipse from the command line in OS X (and Windows and Linux)

The Mac is very easy to use due to its innovative packaging system for applications, where it hides an entire tree of directories inside one file/icon. With Eclipse, this shows up as the Eclipse icon that we know and love.

However, if you’re a hardcore programmer, then you really should get your hands dirty with the command line via OS X’s Terminal. This lets you get down to the UNIX core. When you go into your Eclipse install directory, you’ll find a nice executable named appropriately enough: «eclipse». Well, it’s actually just a symbolic link into the Eclipse.app (the nicely packaged Eclipse application that I mentioned above.)

If you just type «eclipse», you’re in for a rude awakening, as you won’t be able to interact with the UI and you’ll be forced to Control-C. The reason why is due to an obscure implementation of how threading works in the Apple Java Runtime and how it interacts badly with SWT’s (and thus Eclipse’s) expectation of how it should be running.

The solution, however is simple:

./eclipse -vm Eclipse.app/Contents/MacOS/java_swt

The reason why this works is because of a special version of the Java launcher that accommodates SWT’s needs on OS X. You can find out more at the Eclipse Bugzilla, bug 40003.

Here is a nicer version, which lets you see System.out and System.err, as well as Eclipse debug statements, and shows how you can pass in arguments to the underlying VM:

./eclipse -vm Eclipse.app/Contents/MacOS/java_swt -debug -consoleLog -vmargs -Xmx256M

Windows users: You can also run Eclipse from the command line, but you have to make an eclipse.bat file by hand. In this bat(ch) file, include:

eclipse.exe -debug -consoleLog -vmargs -Xmx256M

Linux users: You probably already Eclipse from the command line and you probably don’t need my help doing it. 😉 But just in case you do, use something like:

./eclipse -debug -consoleLog -vmargs -Xmx256M

Windows and Linux users: You can supply the -vm parameter as well if you want to run Eclipse using another VM, like the JDK 1.5 for example.

You can find out more information about command line arguments to Eclipse in the the Eclipse runtime options page in the Eclipse Help.
