Class file output location

[Jon Copperthite]

I would like to separate my source files from my class files in a mirror directory structure. How can I do that with Textpad?

example:
f:\dev\src\com\etc....

all class files would be compiled into these directories:
f:\dev\class\com\etc....

thanks.

You can do that with parameters passed to the jdk:

The java documentation I refer to to answer this is located at:

http://java.sun.com/j2se/1.4/docs/toold ... ml#options


Assuming that you will always follow that directory structure you mentioned above, AND that you only have three package levels, i.e.:
"com.mycom.mypack",
you would need to use the following command line:

javac.exe -d ..\..\..\class FileName.java

This translates, for the default javac compiler supplied by TextPad, to:

Command: UNCHANGED
Parameters: -d ..\..\..\class $File
Initial folder: UNCHANGED

However, if you have multiple package levels, i.e.:
"com.mycom.mypack"
"com.mycom.mypack.mysubpack"
"com.mycom.mypack.myothersubpack"
Then you can't do this flexible solution. In that case, just write out the ABSOLUTE path after the -d parameter:

Command: UNCHANGED
Parameters: -d F:\dev\class\
Initial folder: UNCHANGED

Anyway, that should work with all but the oldest jdk's, which may not support this, though it'll work as far back as jdk 1.1.8.

Garrett Johnson,

This works great, thanks for the answer. However, if I compile another source that depends on the classes in my package, it can't find them. For example, I have utils.java that is a class by itself and is compiled to com.asetech.slideshow. When I compile the next class that depends on utils.java, Textpad tells me that i can't find it. My folder structure is:

d:\slideshow\src\*.java
d:\slideshow\classes\com\asetech\slideshow\*.class

I'm using the compile option -d ..\classes $File. This works great. Just can't compile source relying on classes that went to the package folder.

Can you help?

Thanks.

The -d option takes care of you problem with changing the directory. If you are also worried about other files having trouble finding them, try adding -classpath afterwords as well. Then the compiler wll try down the classpath you specify when it looks for the files.

you should then have:

Command: UNCHANGED
Parameters: -d F:\dev\class\ -classpath f:\dev\class
Initial folder: UNCHANGED
