I want to pass properties from precompiled script plugin to the project itself. I have precompiled script plugin inside of buildSrc directory.
1 In buildSrc/gradle.properties I have defined defaultSpringBootVersion property that holds value of 2.6.3. This property is used in buildSrc/build.gradle to specify the org.springframework.boot plugin version.
2 At the same time I would like that the plugin itself located in buildSrc/src/main/groovy/com.rivancic.convention-gradle-plugin.gradle applies it to project properties:
project.ext{
springBootVersion = defaultSpringBootVersion
}
3 If I try then in root project to access springBootVersion that I expect it will be available through the plugin, I get following error:
An exception occurred applying plugin request [id: 'com.rivancic.convention-gradle-plugin']
> Failed to apply plugin 'com.rivancic.convention-gradle-plugin'.
> groovy.lang.MissingPropertyException: Could not get unknown property 'defaultSpringBootVersion' for object of type org.gradle.internal.extensibility.DefaultExtraPropertiesExtension.
Link to the example project: GitHub - rivancic/gradle-plugin-properties: Example project in passing properties form Gradle plugin to the project itself
