Hello,
I am facing an issue in the path of the file. Whenever I am executing the
below command. The slashes in classpath are replaced with dots and I am
unable to navigate to files in order to run the scripts. Kindly guide why
this is happening and what is the solution. Thank you.
(java $JAVA_OPTS -classpath `cygpath -pu $CLASSPATH`
org.dspace.app.launcher.ScriptLauncher "$@")

By dots, do you mean ":" ? Can you please provide a concrete example of the input and output?

This is a bad idea for at least 2 reasons.
1. the CLASSPATH variable has special meaning and the java executable will act on it if it exists - use $CP or anything else
2. you should "$(...)" not `...`

Seeing as you did not supply specifics it's a little hard to know exactly
what's going on, but it is conceivable that you need to put $CLASSPATH
inside double quotes, i.e., if it has the Windows ; separator in it. Also,
I discovered that if Windows drives are mentioned, such as C:, the next
character needs to be \, that is: C:\..., not (e.g.) C:a\b.
But turning \ or / into . would not have been done by cygpath. That
would be done by Java.
But lastly I note that I am not aware of any version of Java built for
cygwin. Java is a Windows program, so you'd be wanting something more
like:
java $JAVA_OPTS -classpath "$(cygpath -pw "$CLASSPATH")" ...
$(...) is the more modern version of ` `, which is now deprecated.
The " " around $( ) is to prevent the ; in the path from ending the
java command line as it is being processed by bash.
For a path that starts with drive letter C (say), start the path with
/cygdrive/c.

There's multiple issues beyond what has already been mentioned.
3. Missing quotation of an unknown variable.
4. There's no Cygwin Java, and using Cygwin paths with native Java is sure to
cause interoperability issues.

There is no Cygwin Java, so please just define a Windows env var using Windows
paths and separators, do not explicitly specify it in the command line, and run
from a .cmd or .bat to avoid issues and bad assumptions:
set CLASSPATH=C:\Java\classes\lib.jar;C:\Java\classes\util.jar
java %JAVA_OPTS% org.dspace.app.launcher.ScriptLauncher %1 %2 %3 %4 %5 %6 %7 %8 %9

Thank you so much for the response. It is working fine now. I just
replaced `...` with this "$(...)"
