How to set conditional Gradle properties?

How do I set task properties in a Gradle Plugin

• I am creating a gradle plugin to apply the sonar-runner plugin and default many of the values such as the sonar host URL and the sonar JDBC URL. I cannot figure out how to set the properties though. When I set this up in build.gradle I use: apply plugin: 'sonar-runner' sonarRunner { sonarProperties { property 'sonar.host.url', 'http://mySonar.company.com' property 'sonar.jdbc.url', 'jdbc:mysql://127.0.0.1:1234/sonar' } } My gradle plugin looks like: class MySonarPlugin implements Plugin<Project> { @Override void apply(Project project) { project.apply plugin: 'sonar-runner' project.configurations { sonarRunner { sonarProperties { property 'sonar.host.url', 'http://mySonar.company.com' property 'sonar.jdbc.url', 'jdbc:mysql://127.0.0.1:1234/sonar' } } } } } With this setup I get a No signature of method exception. How should I be setting these properties?

• Answer:

  I discovered that I could use project.getExtensions().sonarRunner.sonarProperties{ ... } to set the sonar properties. See example below. class MySonarPlugin implements Plugin<Project> { @Override void apply(Project project) { project.apply plugin:'sonar-runner' project.getExtensions().sonarRunner.sonarProperties { property 'sonar.host.url', 'http://mySonar.company.com' property 'sonar.jdbc.url', 'jdbc:mysql://127.0.0.1:1234/sonar' } } }
