我的eclipse不知道弄啥了现在创建maven项目只有resources目录没有java和test目录，求指教

Eclipse导入Maven项目 导入完后的pom.xml配置文件报叉 请问是什么原因？缺少jar包还是没用阿里云镜像

用eclipse import spring boot官网的demo，出错失败后，创建maven项目提示An internal error occurred during: "Creating maven-archetype-quickstart". Guice provision errors:什么原因  错误详情： An internal error occurred during: "Creating maven-archetype-quickstart". Guice provision errors: 1) Error injecting: private org.eclipse.aether.spi.log.Logger org.eclipse.aether.internal.impl.SimpleLocalRepositoryManagerFactory.logger while locating org.eclipse.aether.internal.impl.SimpleLocalRepositoryManagerFactory at ClassRealm[extension>org.springframework.cloud:spring-cloud-contract-maven-plugin:2.1.2.RELEASE, parent: sun.misc.Launcher$AppClassLoader@c387f44] at ClassRealm[extension>org.springframework.cloud:spring-cloud-contract-maven-plugin:2.1.2.RELEASE, parent: sun.misc.Launcher$AppClassLoader@c387f44] while locating org.eclipse.aether.spi.localrepo.LocalRepositoryManagerFactory annotated with @com.google.inject.name.Named(value=simple) 1 error

我项目导入之后，pom.xml有红叉，找不到jar包，但是我本地仓库有这个jar包，不知道为什么找不到，点了clean 又 maven--》update project还是报错 到底怎么回事，求教   ``` <?xml version="1.0"?> <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <modelVersion>4.0.0</modelVersion> <parent> <artifactId>parent</artifactId> <groupId>com.auchan</groupId> <version>1.0.0-SNAPSHOT</version> </parent> <groupId>com.auchan.web</groupId> <artifactId>web</artifactId> <packaging>war</packaging> <version>1.0.0-SNAPSHOT</version> <name>${project.artifactId} v${project.version}</name> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> </dependency> <!--inner project dependency start --> <dependency> <groupId>com.auchan.service</groupId> <artifactId>service</artifactId> <version>${training.version}</version> <exclusions> <exclusion> <artifactId>commons-fileupload</artifactId> <groupId>commons-fileupload</groupId> </exclusion> <exclusion> <artifactId>log4j</artifactId> <groupId>log4j</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>com.auchan.engine</groupId> <artifactId>engine</artifactId> <version>${training.version}</version> </dependency> <!--inner project dependency end --> <dependency> <groupId>org.tuckey</groupId> <artifactId>urlrewrite</artifactId> </dependency> <dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty</artifactId> </dependency> <dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty-util</artifactId> </dependency> <dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty-naming</artifactId> </dependency> <dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty-plus</artifactId> </dependency> <dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>jsp-2.1</artifactId> </dependency> <dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>jsp-api-2.1</artifactId> </dependency> <!--generate validate code denpendency --> <dependency> <groupId>com.googlecode</groupId> <artifactId>kaptcha</artifactId> </dependency> </dependencies> </project> ```

我的电脑有重装过系统，之前maven仓库是放在了c盘的，所以我觉得这个也有可能影响到 没办法自动下载包， pom.xml里面包的依赖都有写进去了，但是就是找不到包， 我重新把maven仓库的位置定在了其他地方，之前用eclipse+maven有试过一次，就用了那一次的仓库 谁告诉我下，怎么解决这种情况比较好，

从svn中导入项目后出现红色感叹号，检查libraries没有出现红叉，所有包都导入， 但是order and export里面有两个错误不知道怎么解决显示的是两个项目没有导入，这个两个项目的 jar包却是导进来了的，这个项目放到idea中运行没有问题 这个是lib导入的jar包没用maven，order and export里面的东西是没有删除这个选项

 webapp下的index.jsp如何引用resources下的js文件？求大神讲解

- 像这样的效果 

先看图，然后我仔细解释 最近发现找不到文件，同样的代码在eclipse中可以正常找到，对于idea不熟悉，所以来此请教，我是把一些文件拷resources目录下，发现找不到了，使用相对路径，我看到target/classes中是编译过去了的啊，这个路径该怎么写？ 在eclipse中 （1） 主项目包含的两个模块 topsoft-test(web项目) topsoft-utils(java maven项目) （2）（3）（4） 根据new File("log4j.xml);以及创建文件可以发现路径是相对于子项目topsoft-utils 的跟路径，(4)标注了这个测试类是在topsoft-utils中运行的 （5） 假如说我想访问（5）标注处的这个文件，相对路径该怎么写？ 转到IntelliJ IDEA中，目录结构一样，运行的测试也是一样，打印出来的目录不同，我想这是IDE的区别，或者说是在IDEA的配置当中哪里出了问题，导入maven项目我就默认的 Project Structure 我看到里面有三个模块。 路径中只写文件名不是相对于classpath路径么，为什么相对于项目的跟路径了，eclipse中这样可以接受，至少还能加上src/main/....访问到，而在IntelliJ中就完全不对了，主项目打包会产生子项目的jar包，而我访问的文件应该是相对于子项目的classpath路径，在IntelliJ中，resources是在classpath中的，如果只写名字应该是相对于子项目的resources目录才对啊，理论上。 请赐教 我查看了打包编译后的目录，确实是打进去了的，为什么通过只写文件名这种方式就访问不到呢？

在eclipse上用用netty框架写了个demo，直接在eclipse上能编译运行成功，导出了个jar包， 用java -jar 运行后，报出了如下错误： Error: A JNI error has occurred, please check your installation and try again Exception in thread "main" java.lang.NoClassDefFoundError: io/netty/channel/Even tLoopGroup at java.lang.Class.getDeclaredMethods0(Native Method) at java.lang.Class.privateGetDeclaredMethods(Unknown Source) at java.lang.Class.privateGetMethodRecursive(Unknown Source) at java.lang.Class.getMethod0(Unknown Source) at java.lang.Class.getMethod(Unknown Source) at sun.launcher.LauncherHelper.validateMainClass(Unknown Source) at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source) Caused by: java.lang.ClassNotFoundException: io.netty.channel.EventLoopGroup at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 7 more 最开始以为是包没打好， 又重新在manifest里面定义了一下classpath，完事一样还是找不到eventloopgroup class，我工程里面就引用了一个netty-5.0.0.Alpha2，我看了一下这个包，class文件好好的静静的就躺在那里........为什么它找不到，求大神们给个解决方案。。。。

在eclipse中的正常项目，不论是新建还是导入的，只要run as on server就报同样的错，但是在浏览器可以正常访问。 关闭所有项目，新建了一个web项目，只在一个jsp页面写了helloworld，其他地方没有代码，仍然是报同样的错，浏览器正常输出helloworld。tomcat移除后重新配置仍然不能解决问题。 求助，求助，这几天网上各种找资料也没解决。 部分代码如下：

提到“程序员”，多数人脑海里首先想到的大约是：为人木讷、薪水超高、工作枯燥…… 然而，当离开工作岗位，撕去层层标签，脱下“程序员”这身外套，有的人生动又有趣，马上展现出了完全不同的A/B面人生！ 不论是简单的爱好，还是正经的副业，他们都干得同样出色。偶尔，还能和程序员的特质结合，产生奇妙的“化学反应”。 @Charlotte：平日素颜示人，周末美妆博主 大家都以为程序媛也个个不修边幅，但我们也许...

场景 日常开发，if-else语句写的不少吧？？当逻辑分支非常多的时候，if-else套了一层又一层，虽然业务功能倒是实现了，但是看起来是真的很不优雅，尤其是对于我这种有强迫症的程序"猿"，看到这么多if-else，脑袋瓜子就嗡嗡的，总想着解锁新姿势：干掉过多的if-else！！！本文将介绍三板斧手段： 优先判断条件，条件不满足的，逻辑及时中断返回； 采用策略模式+工厂模式； 结合注解，锦...

有小伙伴问松哥这个问题，他在上海某公司，在离职了几个月后，前公司的领导联系到他，希望他能够返聘回去，他很纠结要不要回去？ 俗话说好马不吃回头草，但是这个小伙伴既然感到纠结了，我觉得至少说明了两个问题：1.曾经的公司还不错；2.现在的日子也不是很如意。否则应该就不会纠结了。 老实说，松哥之前也有过类似的经历，今天就来和小伙伴们聊聊回头草到底吃不吃。 首先一个基本观点，就是离职了也没必要和老东家弄的苦...

当HR压你价，说你只值7K时，你可以流畅地回答，记住，是流畅，不能犹豫。 礼貌地说：“7K是吗？了解了。嗯~其实我对贵司的面试官印象很好。只不过，现在我的手头上已经有一份11K的offer。来面试，主要也是自己对贵司挺有兴趣的，所以过来看看……”（未完） 这段话主要是陪HR互诈的同时，从公司兴趣，公司职员印象上，都给予对方正面的肯定，既能提升HR的好感度，又能让谈判气氛融洽，为后面的发挥留足空间。...
