Research direction

Start with the pom.xml and compare application.properties with application-local.properties. Reproduce the packaged launch using mvn clean install and the shown java -jar command, checking how the active profile and Vault configuration are supplied. Done means the local profile's Vault properties are selected during startup without the ${VAULT_ADDR} error.

Description

status: waiting-for-feedback

I'm trying to integrate my Spring Boot app with Vault for loading secrets. The app runs on PCF environment so the main configuration file (application.properties) is configured appropriately. For local development, the vault authentication is done via a regular token. So I have created application-local.properties file with appropriate configuration for local development. Then I set the "Active Profiles" value to "local" under the run/debug configuration.

Problem is that when I try to start the app in IDEA, I get the following error. So it's clear that the vault related properties mentioned in application-local.properties are not being picked up during startup.


23:32:40.289 [main] ERROR org.springframework.boot.SpringApplication - Application run failed
java.lang.IllegalArgumentException: Illegal character in path at index 1: ${VAULT_ADDR}
    at java.base/java.net.URI.create(URI.java:906)
    at org.springframework.cloud.vault.config.VaultConfiguration.createVaultEndpoint(VaultConfiguration.java:121)
    at org.springframework.cloud.vault.config.VaultConfigDataLoader$ImperativeInfrastructure.<init>(VaultConfigDataLoader.java:445)
    at org.springframework.cloud.vault.config.VaultConfigDataLoader.registerImperativeInfrastructure(VaultConfigDataLoader.java:177)

Here is the complete pom and main application.properties and application-local.properties files.

I have generated the deployment artifact using command mvn clean install and then tried to run the app using java -jar demo-0.0.0.1-snapshot.jar -Dspring.profiles.active=local.

Since I'm passing the profile, I was expecting that configuration from the application-local.properties file will be picked up but from the stacktrace it seems like the main configuration file is being read.
