Hello everyone,
I created https://issues.apache.org/jira/browse/CXF-8436. This is about
getting generated code that is "reproducible-build-compatible". This
would mean having @Generated annotations without a date in them.
CXF is the last part in our build that's preventing us from being a
fully reproducible build. So I set out to tackle this :)
I am currently working on a solution where I have correct @Generated
annotations in wsdl2java generated code, and also in xjc generated code.
It involves two pieces:
The first piece is a new project in cxf-xjc-utils, which is a new plugin
for xjc. It allows for a command line flag
"-Xmark-generated-without-date". The plugin is actually an extension of
com.sun.tools.xjc.addon.at_generated.PluginImpl (which is shipped with
jaxb-xjc-2.3.2.jar). This is the plugin responsible for creating
@Generated annotations *with* the 'date' parameter. My code calls the
superclass, and then removes the 'date' part by duplicating the
@Generated annotation. (This is because you can not modify a
JAnnotationUse once it's created.)
The second piece is additional code to codegen-plugin, wsdlto/core,
wsdlto/databinding/jaxb and wsdlto/frontend/jaxws. This code allows for
a command line flag "-mark-generated-without-date". This command line
flag does two things:
- Wsdl2java generates the correct @Generated annotations, without 'date';
- It calls xjc with "-Xmark-generated-without-date"
Now for my questions:
- Is this train of thought something you agree on? If this were a pull
request (two actually), would you accept it?
- Is it ok to have the two command line flags be named differently? I
followed existing JAX-B plugin code and prefixed my command with an 'X'.
I did not do this for wsdl2java.
- What should this new JAX-B project be called? I currently named it
"reproducible-build", but maybe something like
"mark-generated-without-date" is more appropriate?
Thanks in advance for your replies.
With kind regards,
Jurrie
