Question

Eclipse: is there a way to get Eclipse to output the commands given to run your program?

Answer 1

+3 A:

I don't know of any way of getting Eclipse to show any command line arguments - but I'm sure we can solve your problem in other ways.

What is the full name of your class? Is it just MyClass, or is it in some package? You need to supplied the fully qualified name, e.g.
```
java mypackage.MyClass
```
Where are the class files? You need to make sure they're on the class path, e.g.
```
java -classpath bin mypackage.MyClass
```

Yeah your answer solved my problem. I was not familiar with calling something that was in a package because you seem to have to be 1 directory up in order to call it (ie. you can't be in a the Class directory itself. It'd still be nice if eclipse had that feature though

It's not a matter of being "one directory up" - it's that the package *root* has to be in the class path, and you have to specify the fully qualified name.

Answer 2

A:

Eclipse does not pass anything to your java application unless you tell it to in the launch configuration. Check your classpath and your packages, like Jon Skeet already wrote.

Answer 3

A:

Does not Eclipse show the commands in one of the Consoles?

Not for Java. Yes for CDT.

Answer 4

+1 A:

Once you have run a program in eclipse, there is configuration available from the 'debug' and 'run' menus. If you open it, you will see the classpath. From there you can determine what it did.

You can also check the box that writes the launch config to a .launch file, and look at it. It's not precisely the command line, but it will tell you what you need to know.

Answer 5

+4 A:

you can get the exact command used by Eclipse like this:

Run your program inside Eclipse.
Go to the Debug perspective.
Terminate the program, or let it end. right click on the second line. (Terminated, exit value... ) and select properties. in there you will have the full command line used.

Answer 6

A:

Note: if you want to see the exact java command line Eclipse is launching when running your app (from Eclipse), you can:

put a breakpoint at the beginning of your class
launch your app in debug mode
launch a Process Explorer (if you are on Windows, that is)

alt text

You will see under the eclipse.exe (not shown in this picture) the java process.
Double-click on it, go the the Image tab, and copy-paste the value of the field "command-line".
