# 在线仓库里找不到 #

问题：

org.springframework.cloud:spring-cloud-starter-eureka :unknown

pom.xml文件：

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
            </dependency>

原因：这个没有默认版本号，需要确定版本号。

法1：加依赖管理

<dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>Greenwich.SR3</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>

法2：手写版本号

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
                <version>2.2.1.RELEASE</version>
            </dependency>

说明：有的项目里边用了Spring Cloud的这个版本：Finchley.M7，这个版本在此仓库里边有：[JFrog][]

# 包冲突 #

在运行spring的eureka-server时，出现以下错误

The method's class, javax.servlet.ServletContext, is available from the following locations:
    
        jar:file:/E:/work/maven/apache-maven-3.6.3/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar!/javax/servlet/ServletContext.class
        jar:file:/E:/work/maven/apache-maven-3.6.3/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.30/tomcat-embed-core-9.0.30.jar!/javax/servlet/ServletContext.class
    
    It was loaded from the following location:
    
        file:/E:/work/maven/apache-maven-3.6.3/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar

解决方法：删掉E:/work/maven/apache-maven-3.6.3/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar
