Description
We have a slave running on an HP Itanium host (ver. HP-UX unknown B.11.23 U ia64) where the readlink command does not exists. So when trying to resolve symlinks, slave agent fails with the following error:
hudson.util.IOException2: java.io.IOException: Cannot run program "readlink" (in directory "/misc/home_tmp_dstk110/."): readlink: not found

added a comment - Well, no ... But why do you need to use it to retrieve artifacts ?

jna and jna-posix libraries does not support HP Platform.
In jna-posix there is a Posix Factory with following method:
public static POSIX getPOSIX(POSIXHandler handler, boolean useNativePOSIX)
{
POSIX posix = null;
if (useNativePOSIX) {
try {
if (Platform.IS_MAC)
posix = loadMacOSPOSIX(handler);
else if (Platform.IS_LINUX)
posix = loadLinuxPOSIX(handler);
else if (Platform.IS_FREEBSD)
posix = loadFreeBSDPOSIX(handler);
else if (Platform.IS_OPENBSD)
posix = loadOpenBSDPOSIX(handler);
else if (Platform.IS_32_BIT) {
if (Platform.IS_WINDOWS)
posix = loadWindowsPOSIX(handler);
else if (Platform.IS_SOLARIS)
}
if (handler.isVerbose())
if (posix != null)
System.err.println("Successfully loaded native POSIX impl.");
else
System.err.println("Failed to load native POSIX impl; falling back on Java impl. Unsupported OS.");
}
catch (Throwable t)
{
if (handler.isVerbose())
}
}
Any executable can not be run on this platform using the posix library.

added a comment - the closest I come is:
$ touch aFile $ ln -s aFile aLink $ file -h aLink aLink: symbolic link to aFile

I have the same problem on AIX (5.3 and 6.1). And it's kinda vital for me
There was a script you may look at: http://unix.derkeiler.com/Newsgroups/comp.unix.shell/2011-12/msg00221.html
Or if the functionality required measures only to getting the path you can parse the ls -l output. But carefully, because: freya:~/tmp/3>touch file
freya:~/tmp/3>ln -s – file -\>
freya:~/tmp/3>ln -s – file -\>\ 1
freya:~/tmp/3>ln -s – -\>\ 1 file1
freya:~/tmp/3>ls -l
total 0

Anyway why do you need to call external program and not do it in java?
I've added a stopgap fix in this pull request. This doesn't represent a final solution, but might take the heat off things a bit.
Even if i have readlink installed on the host, it doesn't see it:

Do you know any equiavlent command in HP-UX that works instead of readlink?
