🐛 ENVAR replaced when defined.

[jortel]

ENVAR replaced (only) when defined. This prevents replacing variables not associated with ENVAR. For example, in the addon-analyzer, requested resources are expressed in the metadata as $(var).

For example:

  metadata:
    provider:
      address: localhost:$(PORT)
      initConfig:
      - providerSpecificConfig:
          bundles: /jdtls/java-analyzer-bundle/java-analyzer-bundle.core/target/java-analyzer-bundle.core-1.0.0-SNAPSHOT.jar
          depOpenSourceLabelsFile: /usr/local/etc/maven.default.index
          lspServerPath: /jdtls/bin/jdtls
          mavenSettingsFile: $(maven.settings.path)
      name: java
    resources:
    - fields:
      - key: maven.settings.path
        name: settings
        path: /shared/creds/maven/settings.xml
      selector: identity:kind=maven
  selector: tag:Language=Java || !tag:Language

An alternative would be a different syntax. Perhaps $((var)). $[var] $/maven.settings.path/
The $(maven.settings.path) should not be replaced with "" since it's not an ENVAR.
