I am trying to convert the following line from a makefile into perl:
.. shell_script_to_get_env_data && java Main

When run on a Unix command line the
.. shell_script_to_get_env_data
sets some env variables.

Then some objects instantiated from Main.java need to use
those env variables.

The following perl lines don't work:
system(". shell_script_to_get_env_data");
system("java Main");
Main fails because its shell doesn't have the env variables set.

How do I put these commands together in Perl so that the environment
variables set up by the shell script are accessable by the Java
program?

Thanks,
Shawna

How about

system("./shell_script_to_get_env_data && java Main");

Or you could set the environment in perl, then run java:

$ENV{myvar} = "somevalue";
system("java Main");

Have you tried
system(". shell_script_to_get_env_data && java Main");
?
