问题
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.
Logs after using mvn use-latest-versions command.

回答1:
The goal versions:use-latest-snapshots updates only release versions, see Advancing dependency versions :
versions:use-latest-snapshotssearches 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
