spring-boot-maven-plugin @ConditionalOnProperty

Question

i am trying to use @ConditionalOnProperty while starting the application with the spring-boot-maven-plugin.

if i start the project with eclipse i just have to add "-Dexample=true" to the vm Arguments.

@ConditionalOnProperty( name = "example", havingValue = "true", matchIfMissing = false )

i tried to do the same ith the spring-boot-maven-plugin

i tried it with

<jvmArguments>-Dexample=true</jvmArguments>
<jvmArguments>-Dspring-boot.run.arguments="--example=true"</jvmArguments>
<arguments>
<argument>-Dexample=true</argument>
<argument>-Dspring-boot.run.arguments="--example=true"</argument>
</arguments>

but none of these works.

if i add a profile

             <jvmArguments>-Dspring.profiles.active=exampleProfile</jvmArguments>

which contains the argument example:true it works. `

EDIT:

the exact arguement is

<arguments>
 <arguement>openapi.offline=true</arguement>
</arguments>

but the property is still not found

- @ConditionalOnProperty (openapi.offline=true) did not find property 'offline'

my conditional:

 @ConditionalOnProperty( prefix = "openapi", name = "offline", havingValue = "true", matchIfMissing = false )

Answer 1

you don't need the -D Try this:

    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>....</version>
    <configuration>
      <arguments>
        <argument>--openapi.offline=true</argument>
      </arguments>
    </configuration>
