I have a spring boot application that uses gradle. I have configured gradle to inject build parameters into application.properties.
Here is my gradle snippet.
processResources {
expand project.properties
}
In the application.properties, I have following values
service.name=${name}
service.version=${version}
name and version are properties of gradle that will be injected.
when I run ./gradlew bootRun or ./gradlew build, I see the application.properties file being replaced with correct values.
But, when I start the using springBoot Runner from Intellij, I get the following error.
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'Controller': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private java.lang.String com.company.foo.web.Controller.version; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'version' in string value "${version}"

at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:543) ~[spring-beans-4.2.7.RELEASE.jar:4.2.7.RELEASE]
when I replace the application.properties as follow, it works in spring boot runner in intellij but the gradle build fails
service.name=${name: not configured}
service.version=${version : not configured}
how can I tell spring boot to ignore any missing placeholder values ?

BUILD FAILED
EDIT
public class Controller {
@Value("${service.name: not configured}")
String name;
@Value("${service.version: not configured}")
String version
//rest of code
}
I've resolved this by adding into application.yml the following:
${version?:unknown}
It also work from cli:gradle bootRun and also from IntelliJ and you don't have to call the Gradle task processResources before launching in IntelliJ or use spring profiles.
This work with Gradle ver:4.6 and also Spring Boot ver: 2.0.1.RELEASE.
Hope it helps ;)
I have the same problem - really annoying. Best solution I have found so far is to save a run/debug configuration in IntelliJ and then go in an edit the configuration, specifying that the gradle task processResources should be executed before launch.
I solve this with Spring profiles. https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-profiles.html
In application.properties I have
service.version=dev
In application-production.properties I have
service.version=${version}
And finally this in the build.gradle file
processResources {
filesMatching('application-production.properties') {
expand(project.properties)
}
}
In dev, test and integration tests the version will be "dev", when running with the production profile it will use the build version.
This also works when running the application directly from IntelliJ.
