How do you include a classpath wildcard as an argument to a java bash call?


How do you include a classpath wildcard as an argument to a java bash call?

seems to work fine I'm trying to create a bash script that will build a list of arguments before calling java, but I am having trouble getting a classpath argument with a wild card to work. The script so far: , You should use an array with proper quoting:
code :
propfiles='./props/default.properties'

args=(-cp 'lib/*')
args+=(-Xmx10G -Duser.timezone=GMT)
args+=("-Danl.property.files=$propfiles")

java "${args[@]}" main.class.path.Main

Does that help As Ignacio Vazquez-Abrams already notes, on Windows the shell does not do wildcard expansion. That's up to the application. So there is nothing you can do to the shell to stop it from doing something that it doesn't do in the first place.
code :
> echoargs.exe *
arg 1: *

To fix this issue Solution, double quote the classpath argument. Example: -classpath "*" This is necessary on the command line as well as inside a bash script.
A subsequent addendum:
Is it correct to include individual files in the -classpath argument to the Java VM?

Hope that helps Current practice here is to include individual files (other than JAR files, such as configuration files or data files) in the classpath. Is this considered correct and why or why not? , The classpath contains either directories or jar files

I wish this helpful for you Under Debian I had to put quotations marks just around the wildcard for this to work: "*"
Then the compile command becomes:

wish help you to fix your issue Don't use variables to store entire command lines, precisely because you can't accommodate whitespace. Use an array, preferably to hold just the options and specify the command separately.
