公司的项目，都是配置好的，我用的IDE是MyEclipse 10.5，配置的是Maven 3.3.9，以前单独打包安装模块没问题，现在一install就报错：
[WARNING]
[WARNING] Some problems were encountered while building the effective model for ...

[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING]

打开pom发现插件已经安装：
...
org.apache.maven.plugins
maven-compiler-plugin
3.1
1.7
1.7
UTF-8
org.apache.maven.plugins
maven-resources-plugin
2.6

为什么？该怎么做？

Eclipse的Maven包依赖老是不能下载的问题，今天帮别人改bug。在Eclipse中的maven项目很小的一个springboot项目。在build path中老是显示maven依赖包miss。

 

经过一番折腾，最后把maven的setting.xml文件的路径改到D盘就正确了。可能是Eclipse当时没有写入C盘的权限。

resouces-plugin一般是用在maven的resource生命周期的，配置标签应该用<build><plugins><plugin>

在
<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-resources-plugin</artifactId>
    </plugin>
</plugins>

最近在学习JAvaWeb，在第一次使用IDEA（以前没用过）创建maven项目时，老是报错还，没有src目录，下面是错误提示

其实出现这个问题很好解决
千万不要点"Create from archetype"和 “quickstart”



你再创建一次试试，src目录 是不是成功出来了。
