spring cloud 多模块打包部署解决坑
前置条件
笔者使用Intellij IDEA进行Spring Cloud项目创建和部署
Intellij IDEA 版本 ：IntelliJ IDEA 2019.1.3 (Ultimate Edition)
Spring Cloud 版本：Spring Cloud Hoxton.SR1，该版本基于 Spring Boot 2.2.2.Release
maven 版本：3.6.3，其中setting.xml文件为原生文件
主pom.xml配置
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

第一个坑，项目可以通过run进行启动，但是通过 mvn clean命令，报如下错误
?| 123456789101112131415 | [INFO] Scanning for projects...[ERROR] [ERROR] Some problems were encountered while processing the POMs:[ERROR] Non-resolvable import POM: Failure to find org.springframework.cloud:spring-cloud-dependecies:pom:Hoxton.SR1 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced @ line 44, column 25 @ [ERROR] The build could not read 1 project -> [Help 1][ERROR] [ERROR] The project com.albedo:sbe1:1.0-SNAPSHOT (/Users/wangzhangxiong/workspace/jproject/sbe1/pom.xml) has 1 error[ERROR] Non-resolvable import POM: Failure to find org.springframework.cloud:spring-cloud-dependecies:pom:Hoxton.SR1 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced @ line 44, column 25 -> [Help 2][ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.[ERROR] Re-run Maven using the -X switch to enable full debug logging.[ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles:[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/ProjectBuildingException[ERROR] [Help 2] http://cwiki.apache.org/confluence/display/MAVEN/UnresolvableModelException |
该错表面是报https://repo.maven.apache.org/maven2无法加载 org.springframework.cloud:spring-cloud-dependecies:pom:Hoxton.SR1
到本地，笔者通过多种思路，其中包括，更改maven 库镜像为阿里云镜像，添加spring-milestones repository到主pom等方法，也试过降低spring cloud版本，都无法达到有效解决，最后解决办法为将
<!--将该部分的type和scope删除-->
<dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependecies</artifactId> <version>${spring-cloud.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>
改为
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependecies</artifactId>
<version>${spring-cloud.version}</version>
</dependency>
</dependencies>
</dependencyManagement>
此问题可解。
此时如果使用mvn clean或者mvn install命令，则会报错
?| 1234567 | [ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.2.2.RELEASE:repackage (repackage) on project spring-cloud-eureka-cluster: Execution repackage of goal org.springframework.boot:spring-boot-maven-plugin:2.2.2.RELEASE:repackage failed: Unable to find main class -> [Help 1][ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.[ERROR] Re-run Maven using the -X switch to enable full debug logging.[ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles:[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/PluginExecutionException |
这是plugin插件的问题，此时删除spring-boot-maven-plugin插件引入即可
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
多module一起打包问题
将主pom文件新增
<modules>
<module>eureka-server</module>
</modules>
同时新增配置
<packaging>pom</packaging>
最后pom.xml全部配置文件如下
<?xml version="1.0" encoding="UTF-8"?>
