Java project now needs classpaths to run it

Having just moved from NB version 8 to 11.1 there seems to have been a change in the command line needed to run a project.

The OS is Windows 7 Home.

The project has two external libraries: one in the Java modules in the NetBeans 11 directory, and one of my own. In version 8 it was possible to run the program with a command line like

java -jar program.jar

but this no longer works, and I have to put in a command line like

java -cp library paths program.jar

which is a pain, as I can't automate that into a batch file.

Is there any way of getting the libraries (or references to them) included in the jar file? The properties|Libraries|Run tab shows that the classpaths for Compiling Sources and Compiled Sources are included (at least as I understand the symbols on that page). Does the "Build Dependencies" tickbox have any significance here? The lack of a help file means that I can't find out what most of the window items actually mean.

As a rider to this question, there seems to be two small bugs in the Ant script which produces the command line for running the project :

To run this application from the command line without Ant, try:

C:\Program Files\Java\jdk-12.0.1/bin/java -cp C:\Program Files\NetBeans 11\netbeans\java\modules\ext\AbsoluteLayout.jar;D:\Peter\Netbeans\Partitions511\dist\Partitions511.jar;D:\Peter\Netbeans\KillerSudoku11\dist\KillerSudoku11.jar com.ptoye.TestKiller.TestKiller

1) In Windows, the Java executable and Netbeans are in the "Program Files" or "Program Files (x86)" folder. This should have quotes round it to run successfully.

2) In NB 11.1, the output mentions "Netbeans 11" - Shouldn't this be C:\Program Files\NetBeans-11.1?

Dear Eric,

Thanks. I'm Windows-based so the details of *nix flavours rather pass me by.

From running "java --help", I learn that

-p is an alternative to --module-path

Re: Java project now needs classpaths to run it

Posted by Peter Toye <ne...@ptoye.com>.

Dear Geertjan,

Thanks. I wrote to the mailing list address and got the following answer:

  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
  mailman-owner@openjdk.java.net.
  
But that was the address that I mailed! A but recursive. Something wrong up at openJDK methinks. I've tried another address....

I'll file an issue in JIRA.

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.....

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

My main point is that I don't understand how or why this has changed. 


https://openjdk.java.net/projects/jigsaw/

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.

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.

No double quotes round the Java executable directory "Program Files"

What is the version of Java you’re using on the command line?

Re: Java project now needs classpaths to run it

Posted by Peter Toye <ne...@ptoye.com>.

Dear Geertjan,

OK, I've read up on modules and written my first Hello World program which compiles and runs fine using NetBeans. However, it doesn't run from a command line, even after I've removed the mistakes in the Ant-generated suggestion:

D:\>"C:\Program Files\Java\jdk-12.0.1/bin/java" --module-path D:\Peter\Netbeans\TestModules1\build\modules com.ptoye.greetings.Main
Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true
Error: Could not find or load main class com.ptoye.greetings.Main
Caused by: java.lang.ClassNotFoundException: com.ptoye.greetings.Main

The main class is:

package com.ptoye.greetings;
????import com.ptoye.astro.World;
??public class Main {??    
        public static void main(String[] args) {
??            System.out.format("Greetings %s!%n", World.name());
??        }
??}??

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.

Dear Geertjan,

Thanks - I’ll try that. I don't think OpenJDK existed when I last looked at Java. Astonishing how you can get out-of-date so fast.

I agree that Oracle no longer have a JAVA_HOME environment variable to point to the java run-time executable and they don't put it in the PATH, which is a pain, but I can do that myself.

But as far as I can see, the "Libraries" sections of "project properties" are identical for the NB8 and NB11 projects, with a few directory changes. So why is the command line different? Is this a Java issue or has someting changed in the way that NB builds its jar files?

And also, the NB11.1 command line as given by Ant is incorrect - the Java program path needs quotes because of the space in the path. A minor bug, but annoying when you use cut-and-paste to put it into a batch file!

Does this clear things up?

The OS is Windows 7 Home.

The project has two external libraries: one in the Java modules in the NetBeans 11 directory, and one of my own. In version 8 it was possible to run the program with a command line like

As a rider to this question, there seems to be two small bugs in the Ant script which produces the command line for running the project :

To run this application from the command line without Ant, try:

1) In Windows, the Java executable and Netbeans are in the "Program Files" or "Program Files (x86)" folder. This should have quotes round it to run successfully.

2) In NB 11.1, the output mentions "Netbeans 11" - Shouldn't this be C:\Program Files\NetBeans-11.1?

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.

Dear Geertjan,

I agree that the "java" command has nothing to do with Netbeans. I'll try to be more explicit:

My main point is that I don't understand how or why this has changed. I agree that Oracle no longer have a JAVA_HOME environment variable to point to the java run-time executable and they don't put it in the PATH, which is a pain, but I can do that myself.

Does this clear things up?
