Circular placeholder reference when running mvn clean -Pnative native:compile

[andytael]

Hello, I'm trying to compile a spring boot 3.2.2 application using maven (mvn clean -Pnative native:compile) and it fails with the following error message:

Exception in thread "main" java.lang.IllegalStateException: Error processing condition on org.springframework.boot.autoconfigure.liquibase.LiquibaseAutoConfiguration

Caused by: java.lang.IllegalArgumentException: Circular placeholder reference 'spring.datasource.url' in property definitions

The application.yaml file has this configuration:

  liquibase:
    change-log: classpath:db/changelog/controller.yaml
    url: ${spring.datasource.url}
    user: ${liquibase.datasource.username}
    password: ${liquibase.datasource.password}
    enabled: ${LIQUIBASE_ENABLED:true}

  datasource:
    url: ${spring.datasource.url}
    username: ${spring.datasource.username}
    password: ${spring.datasource.password}
    driver-class-name: oracle.jdbc.OracleDriver
    type: oracle.ucp.jdbc.PoolDataSource
    oracleucp:
      connection-factory-class-name: oracle.jdbc.pool.OracleDataSource
      connection-pool-name: Customer32ConnectionPool
      initial-pool-size: 15
      min-pool-size: 10
      max-pool-size: 30

Where the liquibase.url is using the same env var as datasource.url. If I change the liquibase.url value to something else the compilation succeeds. Is this expected, is there a workaround besides adding another environment variable? Attached is a sample application.

I'm using the following Java version:

java version "17.0.10" 2024-01-16 LTS
Java(TM) SE Runtime Environment Oracle GraalVM 17.0.10+11.1 (build 17.0.10+11-LTS-jvmci-23.0-b27)
Java HotSpot(TM) 64-Bit Server VM Oracle GraalVM 17.0.10+11.1 (build 17.0.10+11-LTS-jvmci-23.0-b27, mixed mode, sharing)

I spoke with the GraalVM dev team and they told me the following:
correct me if I am wrong but this build has never reached the native-image builder. It seems to fail in java in the following task: org.springframework.boot:spring-boot-maven-plugin:3.2.2:process-aot. If this is the case, it would be the best to report this ticket to the Spring Boot issue tracker

Thanks
Andy

The problem's in your YAML file where spring.datasource.url has been set to ${spring.datasource.url}:

spring:
  application:
    name: customer32

  liquibase:
    change-log: classpath:db/changelog/controller.yaml
    url: ${spring.datasource.url}
    user: ${liquibase.datasource.username}
    password: ${liquibase.datasource.password}
    enabled: ${LIQUIBASE_ENABLED:true}

  datasource:
    url: ${spring.datasource.url}
