问题1:
-Dmaven.multiModuleProjectDirectory system propery is not set. Check $M2_HOME environment variable and mvn script match.
解决1:
- 可以设一个windows os's环境变量M2_HOME指向你的maven安装目录
- M2_HOME=D:Appsapache-maven-3.3.1
- 然后在Window->Preference->Java->Installed JREs->Edit
- 在Default VM arguments中设置
- -Dmaven.multiModuleProjectDirectory=$M2_HOME
问题2:
java.lang.ClassNotFoundException: org.springframework.web.util.IntrospectorCleanupListener /org.springframework.web.context.ContextLoaderListener
解决2:
- 选中项目->右键Properties->选择Deployment Assemby->选择Add->选中Java Build Path Entries->Next->选择Maven Dependencies->Finish->Apply->OK
问题3:
The import com.tsxs.common.tool.ValidateCodeImg cannot be resolved
解决3:
- Eclipse -> Project -> Clean...
- Ok.
问题4:
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'shiroDBRealm' is defined
解决4:
- <property name="realm" ref="shiroDBRealm" />
- <bean id="shiroDbRealm" class="com.tsxs.security.ShiroDbRealmUser"></bean>
- 配置id和ref的大小写不一致(ctrl+f搜索不区分大小写一致).字母B/b.

解决6:
- 最终解决:
- 1使用软件"010 Editor是一个全新的十六进位文件编辑器"查看文件头有乱码,删除保存就ok了.
- 2由于,我,重新整理的分区(双系统),无奈下,我重新搭建了一个项目,复制代码过去就ok了.
问题7:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12.4或Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin: 2.4..
解决7:
- 解决:重启一下console-nexus.bat就好了,或删除本地maven仓库对应的包(涉及到的根包一起删)
问题8:

[ERROR] [Help 2] http://cwiki.apache.org/confluence/display/MAVEN/ModelParseException
[ERROR] [Help 2] http://cwiki.apache.org/confluence/display/MAVEN/ModelParseException
解决8:
- dependency没有在dependencies里面
问题9:
maven中加入新的:dependency在install的时候,报错nexus没有相应的jar包
解决9:
- 主要删除本地maven的repositories下的相应位置jar的路径,重新install就ok.
- 或者重启nexus或没有启动nexus。
问题10:
Java Project转maven project因为出错没有Maven Dependencies路径
解决10:
- 工程右键:Maven->Disable Maven Nature
- 然后,再次重新转maven:
- Configure->Convert to Maven Project. ok!
注:一般不用重启nexus服务器,除非由于进程端口占用或者服务停止,或者服务器关机或者死机,删除本地相对应的路径文件,clean install 则解决!
问题11:
设置pom.xml后,clean install编译不报错,就是不能加载Maven Dependencies和下载jar包
解决11:
- 因为<dependency>在<dependencies>中,但<dependencies>又在<dependencyManagement>中,删除最外层的<dependencyManagement>后,clean install 则解决!区别解释,备注附件!
问题12:
如果pom.xml中<dependency>标签报错画红线并报红叉,错误:Missing artifact mycoding.kaka:kaka:jar:0.0.1
在Markers中报错:
Description Resource Path Location Type
Missing artifact mycoding.kaka:kaka:jar:0.0.1 pom.xml /zJavaDemo line 20 Maven Dependency Problem
在Markers中报错:

此问题解决,也适合第三方无依赖jar和本地扩展类加入maven统一管理

解决14:
- workspace下本项目的.setting下org.eclipse.jdt.core.prefs文件(修改和jdk一致版本):
- eclipse.preferences.version=1
- org.eclipse.jdt.core.compiler.codegen.inlineJsrBytecode=enabled
- org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.8

解决15:
- 项目右键 --> properties --> Java Build Path的libraries保证只有:JRE System Library[jdk1.8.0.66]和 Maven Dependencies
- 注:如果还有Apache Tomcat v8.0[Apache Tomcat v8.0]则,Remove删除它,在pom.xml中添加以下依赖让maven统一管理!
- 注:版本看自己jdk和tomcat版本

备注附件(解释学习自网络资料,非常感谢作者):
- dependencyManagement:
- Maven 使用dependencyManagement 元素来提供了一种管理依赖版本号的方式。通常会在一个组织或者项目的最顶层的父POM 中看到dependencyManagement 元素。使用pom.xml 中的dependencyManagement 元素能让所有在子项目中引用一个依赖而不用显式的列出版本号。Maven 会沿着父子层次向上走,直到找到一个拥有dependencyManagement 元素的项目,然后它就会使用在这个dependencyManagement 元素中指定的版本号。
- 如果有多个子项目都引用同一样依赖,则可以避免在每个使用的子项目里都声明一个版本号,这样当想升级或切换到另一个版本时,只需要在顶层父容器里更新,而不需要一个一个子项目的修改 ;另外如果某个子项目需要另外的一个版本,只需要声明version就可。
- dependencyManagement里只是声明依赖,并不实现引入,因此子项目需要显式的声明需要用的依赖。
- dependencies:
- 相对于dependencyManagement,所有声明在dependencies里的依赖都会自动引入,并默认被所有的子项目继承。如果你要发布同样的代码,但是由于技术原因需要生成两个单独的构件,你就要使用一个分类器(classifier)。
- classifier:
- 如果你要发布同样的代码,但是由于技术原因需要生成两个单独的构件,你就要使用一个分类器(classifier)。
- 例如,如果你想要构建两个单独的构件成JAR,一个使用Java 1.4 编译器,另一个使用Java 6 编译器,你就可以使用分类器来生成两个单独的JAR构件,它们有同样的groupId:artifactId:version组合。
- 如果你的项目使用本地扩展类库,你可以使用分类器为每一个目标平台生成一个构件。分类器常用于打包构件的源码,JavaDoc 或者二进制集合。
