Re: Java project now needs classpaths to run it
It's pretty common-place (at least in *nix) for commands to support both GNU style and POSIX style arguments with both alternatives for most things. From running "java --help", I learn that --module will do the same as -m and -p is an alternative to --module-path On 10/21/19 5:56 AM, Peter Toye wrote: Re: Java project now needs classpaths to run it Why the Java designer can't just stick to a single syntax is beyond me.

Dear Geertjan,

You are not allowed to post to this mailing list, and your message has
been automatically rejected. If you think that your messages are
being rejected in error, contact the mailing list owner at

It still gives problems, but I'll try your suggestion of trying to join the
openJDK mailing list.
So the Ant script output now has three bugs:
No double quotes round the Java executable directory "Program Files"
"-module-path" should read "--module-path"
"-m" needed before the main class.
Why the Java designer can't just stick to a single syntax is beyond me.

There is now a module system in Java, meaning that there is now a module path

Re: Java project now needs classpaths to run it
Dear Geertjan,
Thanks again. I'd found that page, and the code I produced was a copy of the
code there. It seems that a "-m" option is needed to indicate the main class.
It still gives problems, but I'll try your suggestion of trying to join the
openJDK mailing list.
So the Ant script output now has three bugs:
No double quotes round the Java executable directory "Program Files"
"-module-path" should read "--module-path"
"-m" needed before the main class.
Why the Java designer can't just stick to a single syntax is beyond me.
Best regards,
Peter

That should help, it includes the java command line syntax you're looking for.

Indeed, yes, it would be very useful to everyone if you'd join the openjdk
mailing lists and explain the problems you're having running java on the
command line -- they need to know that otherwise they'll never hear from you
and never make it work the way you'd like.

Where does one go from here? I'm using the Oracle version of Java, Would
OpenJDK make any difference? AFAICS it's the same.
Thanks for the mailing list link. I looked at them but they all seem to be
oriented towards people developing OpenJDK rather than users. There isn't a
"support" or "help" link on the OpenJDK site.
Best regards,

Dear Geertjan,
I agree that the "java" command has nothing to do with Netbeans. I'll try to be
more explicit:
I have a project which dates back to about 2006 and has a main class which I'll
call A. This uses a separate class B which I developed separately. I included B
as a library using A's project properties.
Using Netbeans 8 (and earlier) it was possible to run the project using a
command line like
java -jar A.jar
and the program ran. The Java version was 1.8. The path to the Java executable
is in my PATH.
Earlier this year I wanted to develop it further, and decided to move to the
latest version of NetBeans (11.1) and Java (12). Now the command line as given
in the build output is
C:\Program Files\Java\jdk-12.0.1/bin/java -cp directory\A.jar;directory\B.jar
classpath.A
My main point is that I don't understand how or why this has changed.

There is now a module system in Java, meaning that there is now a module path
and a class path. That was not there in JDK 8 and is now there since then.
Can you join the Java mailing lists and discuss further there:

That should help, it includes the java command line syntax you're looking
for.
