Command line argument is too long when using Maven's jaxws wsgen plugin because of long classpath

Question

I'm trying to generate web service artifacts using the org.jvnet.jax-ws-commons jaxws-maven-plugin and the wsgen goal. It seems that part of the process is to execute a command that includes all the project jars on the classpath and this results in a command that exceeds character limit of the command line by more than double (on Windows 7). How can I workaround this?

[INFO] --- jaxws-maven-plugin:2.3:wsgen (generate-wsdl) @ interface ---
[INFO] Processing: com.mycompany.myproject.MyWebService
[INFO] jaxws:wsgen args: [-keep, -s, D:\Dev\myproject\target\generated-sources\wsgen, -d, D:\Dev\myproject\target\classes, -encoding, Cp1252, com.mycompany.myproject.MyWebService]

The command line is too long.

Answer 1

This is a known bug (JAX-WS-COMMON-110) that will be fixed in version 2.3.1.

Until jaxws-maven-plugin 2.3.1 is officially released, you may compile it from svn.

svn checkout https://svn.java.net/svn/jax-ws-commons~svn/tags/jaxws-maven-plugin-2.3.1-b03
cd jaxws-maven-plugin-2.3.1-b03
mvn install

And then update your pom.xml to use the 2.3.1-b03 version:

<plugin>
    <groupId>org.jvnet.jax-ws-commons</groupId>
    <artifactId>jaxws-maven-plugin</artifactId>
    <version>2.3.1-b03</version>
...
</plugin>

Answer 2

You don't need to build the updated version yourself, it can be downloaded from the Maven repository
