                          maven install 安装项目问题总结

1. 环境 jdk 与项目 jdk 与 开发工具 jdk 保持一致;

2. springBoot项目中不能有多个main方法,必须有一个main方法; 

2.1 缺main方法

3.聚合工程或分布事项目打包时发现找不到对应的类时在pom中加入如下配置:

[ 报错信息: Failed to execute goal: ...Compilation failure: Compilation failure: ]

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>${spring-boot-version}</version>
    <configuration>
        <classifier>exec</classifier>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
        </execution>
    </executions>
</plugin>

web主项目中添加

程序入口pom:

 <build>
    <finalName>len-web</finalName>

      <plugins>
        <plugin>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-maven-plugin</artifactId>
          <configuration>
            <fork>true</fork>
            <mainClass>com.len.Application</mainClass>
            <layout>ZIP</layout>
          </configuration>
          <executions>
            <execution>
              <goals>
                <goal>repackage</goal>
              </goals>
            </execution>
          </executions>
  </plugin>
        <!--<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-war-plugin</artifactId>
        <version>2.6</version>
        </plugin>-->

      </plugins>
  </build>

4.构建镜像时往往可能会发生一个问题

构建镜像一般用脚本构建,第一步先maven install 项目;

比如我在开发工具idea中 maven install 的时能把所有微服务安装成功 ,

但是在命令台执行 有依赖关系的项目时:

mvn -f ../len-core/pom.xml install    成功!
mvn -f ../len-sys/pom.xml install 缺少他依赖的之前安装成功的[len-core]的jar包;

原因是可能自己在开发工具中用的maven seting文件与maven用的seting文件不是同一个,导致了maven安装的jar包路径与工程读取jia包的路径不同;这样我们可以吧maven默认的seting改成开发工具中引入的一致;

 

6. COMPILATION ERROR

pom 文件中缺:

<bootclasspath>${java.home}/jre/lib/rt.jar;${java.home}/jre/lib/jce.jar</bootclasspath>

 

 

8.maven编译时报错：致命错误: 在类路径或引导类路径中找不到程序包 java.lang

Compiling 685 source files to /var/lib/jenkins/workspace/tc_vsmp_test/WebRoot/WEB-INF/classes
致命错误: 在类路径或引导类路径中找不到程序包 java.lang

Build step 'Deploy war/ear to a container' marked build as failure
Finished: FAILURE

分析：

这个问题是因为对于tomcat 7的user的权限定义引起的,如下

manager-gui — Access to the HTML interface. 

manager-status — Access to the "Server Status" page only. 

manager-script — Access to the tools-friendly plain text interface that is described in this document, and to the "Server Status" page. 

manager-jmx — Access to JMX proxy interface and to the "Server Status" page.

必须把部署用户的权限定义为“manager-script”，才可以成功部署。

解决办法：

1、需要修改一下tomcat的conf文件夹下的tomcat-users.xml文件

 

<role rolename="manager-gui"/> 

<role rolename="manager-script"/>

  <user username="admin" password="admin" roles="manager-gui,manager-script"/>

2、重启服务即可（linux下）

    ./shutdown.sh

    ./startup.sh
