Remove cyclic dependencies in wsdl2java code.
---------------------------------------------
Key: CXF-1452
URL: https://issues.apache.org/jira/browse/CXF-1452
Project: CXF
Issue Type: Wish
Components: Tooling
Reporter: Glen Mazza
Priority: Minor
Currently there are two cyclic dependencies in our WSDL2Java code: between
{cxf-tools-wsdlto-core, cxf-tools-wsdlto-databinding-jaxb} and
{cxf-tools-wsdlto-core, cxf-tools-wsdlto-frontend-jaxws}
Databinding needs Core's DefaultValueProvider
Core needs databinding's tools-plugin.xml
Frontend needs Core's WSDLToProcessor
Core needs frontend's tools-plugin.xml
The "Core" requirements are because Core contains WSDL2Java class. Because
WSDL2Java needs packages outside of Core, I think it would be best to either
place WSDL2Java in its own module, or keep it where it is but create a new
"common" module under wsdl2 that would hold DefaultValueProvider,
WSDLToProcessor (and perhaps a few other needed classes). If the
latter,databinding and frontend would have this new wsdl-common as a dependency
but not wsdl-core anymore.
Background: I was having trouble debugging WSDL2Java in Eclipse. I imported
just the cxf-tools-wsdlto-core project into the IDE, but running WSDL2Java in
debug mode raised errors that it needed the frontend and databinding modules.
After adding the following dependencies to cxf-tools-wsdlto-core:
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-tools-wsdlto-databinding-jaxb</artifactId>
<version>${project.version}</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-tools-wsdlto-frontend-jaxws</artifactId>
<version>${project.version}</version>
<scope>runtime</scope>
</dependency>
and then running mvn eclipse:clean eclipse:eclipse again from this core
directory, wsdl2Java worked fine. *But* this introduces a cyclic dependency
with databinding and frontend (they both have core as a dependency), so "mvn
install" won't work in any higher-level directory of core.
