Maven update version of specific dependency

Question

I am trying to update the version of particular dependency in my Spring Boot project using the below command. However the dependency version is not getting updated. This is the command I am using:

mvn versions:use-latest-snapshots -Dincludes=com.example:drools-sample-proj

Spring Boot project's dependency:

<dependency>
    <groupId>com.example</groupId>
    <artifactId>drools-sample-proj</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

My local Maven repository .m2 folder contains 2 versions of drools-sample-proj:

• 0.0.2-SNAPSHOT
• 0.0.3-SNAPSHOT

My Spring Boot's project pom.xml is not getting updated for that dependency with 0.0.3-SNAPSHOT with this build command:

mvn versions:use-latest-snapshots -Dincludes=com.example:drools-sample-proj

Build console logs:

Spring Boot version: 1.5.9

Spring Boot project's pom.xml:

<build>
    <finalName>springboot-rule-service</finalName>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

I am using embedded Maven in Spring STS IDE. Am I missing anything here or my understanding on update of pom.xml is incorrect? Any insights would be helpful.

Answer 1

The goal versions:use-latest-snapshots updates only release versions, see Advancing dependency versions :

versions:use-latest-snapshots searches the pom for all non-SNAPSHOT versions which have been a newer -SNAPSHOT version and replaces them with the latest -SNAPSHOT version.

but in your POM is a snapshot version:

Spring Boot project's dependency:

<dependency>
     <groupId>com.example</groupId>
     <artifactId>drools-sample-proj</artifactId>
     <version>0.0.1-SNAPSHOT</version>
</dependency>

so the dependency is not changed.

You could use the goal versions:use-latest-versions, see Versions Maven Plugin :

Replaces any version with the latest version.

Your modified command line:

mvn versions:use-latest-versions -DallowSnapshots=true -Dincludes=com.example:drools-sample-proj
