如何使用Maven Eclipse和glassfish调试Web应用程序？

Question

I create simple web application as maven project. Run mvn eclipse:eclipse and import it into Eclipse worck space. I also has a Glassfish. I run maven goal "clean install" and add properties:

maven.compilet.debug=true
maven.compilet.debuglevel=lines,vars,sources

I run this goal with properties from Eclipse and get war archive. Next I imported war into workspace then click "add and remove" on glassfish and during an "Publish to Glassfish" process project I get and error:

Unable to install breakpoint SomeClass s_ss_WeldSubdass due to missing line number attributes. Modify compiler options to generate line number attributes.

Reason:
Absent Line Number Information

I also check web server properties:

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9009

And check from admin console that debug enabled on 9009 port.

What is the problem?

PS I can create a breakpoint, but debug will be in unknow line.

You could try adding debug options to your maven compiler plugin configuration. By default its value is true, but perhaps your configuration for maven compiler plugin is not in a good way. It would be something like this,

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>${java.version}</source>
                <target>${java.version}</target>
                <debug>true</debug>
            </configuration>
        </plugin>
