我正在尝试使用以下命令更新Spring Boot项目中特定依赖项的版本。但是依赖版本没有得到更新。这是我正在使用的命令：
mvn versions:use-latest-snapshots -Dincludes=com.example:drools-sample-proj
Spring Boot项目的依赖：
<dependency>
<groupId>com.example</groupId>
<artifactId>drools-sample-proj</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
我的本地Maven存储库.m2文件夹包含2个版本的drools-sample-proj：
My Spring Boot的项目pom.xml没有使用此构建命令使用0.0.3-SNAPSHOT更新该依赖项：
mvn versions:use-latest-snapshots -Dincludes=com.example:drools-sample-proj
构建控制台日志：

Spring Boot版本：1.5.9
Spring Boot项目＆＃39; pom.xml：
<build>
<finalName>springboot-rule-service</finalName>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

我在Spring STS IDE中使用嵌入式Maven。我在这里遗漏了什么，或者我对pom.xml更新的理解不正确？任何见解都会有所帮助。
使用mvn use-latest-versions命令后记录。
使用此命令时出现异常： mvn版本：use-latest-versions -Dincludes = com.example.brms：drools-sample-proj -X

我已经使用过此命令，此命令将更新pom中的所有版本！
mvn versions:display-dependency-updates
答案 1 :(得分：0)
目标versions:use-latest-snapshots仅更新发布版本，请参阅Advancing dependency versions ：
versions:use-latest-snapshots在pom中搜索所有非SNAPSHOT版本，这些版本是较新的-SNAPSHOT版本，并用最新的-SNAPSHOT版本替换它们。
但在您的POM中是快照版本：
Spring Boot项目的依赖：
<dependency> <groupId>com.example</groupId> <artifactId>drools-sample-proj</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency>
所以依赖关系不会改变。
您可以使用目标versions:use-latest-versions，请参阅Versions Maven Plugin ：
替换最新版本的任何版本。
您修改过的命令行：
mvn versions:use-latest-versions -DallowSnapshots=true -Dincludes=com.example:drools-sample-proj
