-Xfluent-builder is not supported

[Vishal-Joshi]

I used to use org.jvnet.jaxb2.maven2:maven-jaxb2-plugin v0.14.0 to create builders in generated classes using -Xfluent-builder

However, when I switch to org.jvnet.jaxb:jaxb-maven-plugin v2.0.9 the argument -Xfluent-builder is not supported.
I tried using the -Xfluent-api as mentioned here https://github.com/highsource/jaxb-tools/wiki/JAXB2-Fluent-API-Plugin
but that generates the with* methods and not Builder in the generated class.

Are builders not supported anymore?

Hi @Vishal-Joshi

Could you share a code sample of expected ?

I've created test project (that I'll push in next v4) and generated code is like :

public Address withStreet(String value) {
  setStreet(value);
  return this;
}

public Address withNumber(int value) {
  setNumber(value);
  return this;
}

So you can chain code like

Address a = new Address().withStreet("MyStreet").withNumber(10);

Moreover, could you tell me from where the -Xfluent-builder arg came from ? Which xjc plugin ? Thanks

Hi @laurentschoelens
-Xfluent-builder from org.jvnet.jaxb2.maven2:maven-jaxb2-plugin v0.14.0 would created a builder method in the unmarshalled class from xml. It is the implementation of builder pattern

A sample class would invocation would look like,

FactSet factSet = FactSet.builder()
                    .withFact(builder().withType("type1").build(), builder().withType("type2").build())
                    .build();

where FactSet was an unmarshalled class from a given xml. The builder() and build() were added by the jaxb plugin's xjc implementation

Thanks but the Xfluent-builder does not came from here. Could you share sample pom.xml config ?

[laurentschoelens]

One option I'm thinking of is that the xjc plugin responsible of handling Xfluent-builder is defined in parent pom.xml in plugin / pluginManagament configuration with the older coordinates (org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.14.0) but since you move to the newest version of jaxb-tools for jaxb2 (2.0.9), the configuration is no more inherited from parent.

I'm also pretty sure you are using the following library : https://github.com/mklemm/jaxb2-rich-contract-plugin which refers to same configuration as yours.

I'll try to contact or propose PR to update documentation according to latest version of jaxb-tools.

Feel free to reopen issue if you still have problems, providing more details. Thanks
FI : 4.0.0 of net.codesup.util:jaxb2-rich-contract-plugin has just been released, with support of JAXB4
It should take a few hours before getting to maven-central

[mklemm]

Because the plugin doesn't support JAXB 2 anymore, the "2" has been removed from the artifactId. It's called:
net.codesup.util:jaxb-rich-contract-plugin:4.2.0.0 now...
