gradle xjc

mdesales@ubuntu [01/23/2015 0:12:22] ~/dev/github-intuit/mdesales/service-forms-availability (master *) $ gradle xjc
:xsd-dependency-tree
jaxb: starting Namespace Task
There is no targetNamespace attribute for file '/home/mdesales/dev/github-intuit/mdesales/service-forms-availability/src/main/resources/schema/formsAvailability.xsd' (assigning filname as namespace to it). A Schema should ALWAYS include a targetNamespace attribute at its root element.  No targetNamespace are categorized as using the Chameleon Design Pattern, which is not an advisable pattern, AT ALL!

Full Instructions

1. Create the "schema.xsd" file with the schema you need.
2. Create the "build.gradle" with the settings from https://github.com/jacobono/gradle-jaxb-plugin
3. Make sure that you have the dependencies for buildscript on top and then the regular dependencies
4. Declare the plugin
5. Declare the dependencies to the plugin
6. Declare the Jaxb->xjc with the settings defined at https://github.com/jacobono/gradle-jaxb-plugin#xjc-convention
7. Similar to running the command manually, this will be ready to run. See the output of "gradle xjc" for the output.
8. If you want to add in version control, you can just verify the changes and see that at least the date of the files were changed using "git status".

You can customize Gradle to generate the source before compiling the classes.

😄

Nice instructions. I changed the classes to reside in generated dir. Then add that to the main src set. Keep the main src set clean

jaxb {
xjc {
xsdDir = "src/main/resources/schema"
destinationDir = "src/generated/java"
generatePackage = "com.shane.alycon.raidr.xml.undertakr"
}
}

sourceSets {
main {
java {
srcDir 'src/generated/java'
}
}
}

Thanks shavo007, nice tips

Hi shavo007 this code is not working for me...it is not generating java class
