Use of sourcepath option

Howdy All!

I am trying to use -sourcepath and am becoming a little frustrated as to why
this doesn't work:

F:\java\tests\wtk\bin>javac -sourcepath ..\src -d ..\classes Command1.java
error: cannot read: Command1.java
1 error

F:\java\tests\wtk\bin>dir ..\src
Volume in drive F is BARRACUDA1
Volume Serial Number is 9CE5-75F0

Directory of F:\java\tests\wtk\src

27/03/2004 09:15 AM <DIR> .
27/03/2004 09:15 AM <DIR> ..
27/03/2004 09:15 AM 1,492 Command1.java
1 File(s) 1,492 bytes
2 Dir(s) 9,938,026,496 bytes free

F:\java\tests\wtk\bin>

Any ideas would be most appreciated!

What happens if you use quotes e.g. "\src" ?

or an absolute path e.g. "f:\java\tests\wtk\src" ?

or / in filenames e.g. "../src".

I have never used -sourcepath. It is easier to just do a CD to the
source files.

If you figure it out , please report back so I can add a note to

Hi Tony!

Command1.java[color=darkred]

> javac -sourcepath ..\src -d ..\classes ..\src\Command1.java

Maybe I misunderstood, but I do not think this is the solution. The compile
command will work with or without -sourcepath if I include the path as part
of the last argument:

F:\java\tests\wtk\bin>javac -d ..\classes ..\src\test\HelloWorld.java

F:\java\tests\wtk\bin>java -cp ..\classes test.HelloWorld
Hello World!

F:\java\tests\wtk\bin>javac -sourcepath ..\src -d ..\classes
...\src\test\HelloWorld.java

F:\java\tests\wtk\bin>java -cp ..\classes test.HelloWorld
Hello World!

F:\java\tests\wtk\bin>

A gather than -sourcepath is just an additional set of directories to
look in for source code referenced in the *.java files you mention on
the command line. It does not change the default directory.

Hummm..
Looks like sourcepath will be used to find other classes (or *.java) but the
actually file to be compiled must be named explicitly.

Given (say) c:\a\X.java and c:\a\b\Y.java -
if Y.java references X.java then from c:\a\b you can compile Y.java thus:
javac -sourcepath .. Y.java
If X.java and Y.java are both in C:\a and you compile from c:a\b you need:
javac -sourcepath .. ..\Y.java
If Y.java does not reference X.java then, from c:\a\b
javac ..\Y.java

X.java will also be compiled if required.
Sorry - badly explained - can someone do it properly please?

The manuals really don't make this clear.
