System Properties

Parameters will firstly been searched in System Properties, which includes:

• gradle.properties: systemProp.param1=value1
• settings.properties: systemProp.param1=value1
• ~/.gradle/gradle.properties (not suggested for this plugin)
• Command line: -Dparam1=value1 -Dparam2=value2 -Dparam3=value3

Variables:

Variables that can be used in template files.

name	description	sample
groupId	project.group	com.lodsve
artifactId	project.name	service-demo
packageName	package name	com.lodsve.demo
packagePath	package path	com/lodsve/demo
version	project.version	1.0.0-SNAPSHOT
author	project.author	Administrator
port	servicePort	8080
contextPath	serviceContextPath	/

Adding Custom variables

Extra variables can be added via command line or programmatically with the com.lodsve.gradle.archetype.binding prefix.

Command line :

-Dparam1=value1 -Dparam2=value2 -Dparam3=value3 ...

Property prefix :

System.setProperty('com.lodsve.gradle.archetype.binding.param1', value1)

Programmatic Customization of Bindings

Often, additional variables (bindings) need to be created based on the values of existing variables after they have been resolved (e.g., when they are entered in interactive mode), but prior to the start of the actual generation process.

The generate task can be configured with a processor that is called just prior to the actual file generation, but after all other variables have been resolved. The processor is just a closure that accepts a single argument, the current binding configuration as a Map. The processor is specified by setting the bindingProcessor property of the generate task.

For example:

generate {
    bindingProcessor = { bindings ->
        bindings.capitalizedName = bindings.name.capitalize()
    }
}

Token Format

• In code: @variable@
• In file name: __variable__

Additional GString expressions can be defined between the @ and __ tokens :

• @variable.capitalize()@
• __new Date()__

See GStringTemplateEngine

Generated Project(s) Folder

Fixed to: generated.

Non-templates:

Files that will not be resoled by variables, as they would fail if tried to resolve. Put the non-template lists to .nontemplates file, and put the file to template folder (such as src/main/resources/templates) or src/main/resources/.

Sample:

# comments
**/*.jar
**/*.bat
**/*.sh
**/*.zip
**/*.gz
**/*.xz
**/*.tar
**/*.7z

gradle/
.gradle/
gradlew
gradlew.bat

It follows ant style. The tailing slash for directory is mandatory.

Known Issues

• Doesn't work with property files that have such escapes: key=https\://aaa.bbb.ccc/xxx, remove the \ escape to have it work.
• In interactive mode, the prompt text got truncated sometimes.
