# jh\_classpath(1)

sets classpaths in jar files

## NAME

jh\_classpath - sets classpaths in jar files

## SYNOPSIS

**jh\_classpath** \[*debhelper options*\]

**jh\_classpath** \[*debhelper options*\] \[**-p***package*\] \[**--classpath=***cp*\] \[*jar \[...\]*\]

## DESCRIPTION

**jh\_classpath** is a javahelper program that can set the classpath on jar files for you.

It has two modes of operations.  By default, it will read *debian/package.classpath* or *debian/classpath* and set the classpath of all jar files listed in that file.  In this mode, **jh\_classpath** does not accept any non-option arguments.

Alternatively, you can pass **jh\_classpath** a list of jar files to update.  It will process each of those and set the classpath of them to that value set by **--classpath** if passed.  If **--classpath** is omitted the environment variable CLASSPATH will be used instead (rewriting its contents as necessary).  In this mode, **jh\_classpath** will not read *debian/package.classpath* nor *debian/classpath*.

## FILES

- *debian/package.classpath*, *debian/classpath*

  Parsed to determine which jar files should be processed for the given package.  Note that unlike most other debhelper commands, **jh\_classpath** will use *debian/classpath* as a fallback configuration file for *all* packages that it acts on.  Other debhelper commands usually only apply this fallback to the "main package".

  The file consists of 0 or more lines with the following:

  ```
       jarfile classpath-file1 [... classpath-file2]
  ```

  Note that each file in the classpath is space-separated in this configuration file.

## OPTIONS

- **-c***cp*, **--classpath=***cp*

  Beyond the above, **jh\_classpath** also accepts the shared debhelper options documented in [**debhelper**(7)](/debhelper/7.md).

## SEE ALSO

[**debhelper**(7)](/debhelper/7.md)

This program is a part of javahelper and uses debhelper as backend. There are also tutorials in /usr/share/doc/javahelper.
