一、添加依赖到pom.xml <!-- https://mvnrepository.com/artifact/commons-io/commons-io --><dependency><groupId>commons-io</groupId><artifactId>commons-io</artifactId><version>2.6</version></dependency><!-- https://mvnrepository.com/artifact/org.apache.commons/commons-csv --><dependency><groupId>org.apache.commons</groupId><artifactId>commons-csv</artifactId><version>1.6</version></dependency>二...
解决方式
删除图片中指向jar包，然后更新maven即可原文：https://www.cnblogs.com/5200flyer/p/14832797.html
报错：org.apache.subversion.javahl.ClientException: RA layer request failed svn: Commit failed (details follow)解决方案：1、进入C:\Users\Administrator\AppData\Roaming\Subversion\auth 删除auth下所有文件 （AppData文件默认是隐藏的，记得显示隐藏文件，不然会找不到的）2、打开eclipse中 windows —> Preferences—>SVN 3、将SVN接口改成SVNKit原文：https://www.cnblogs.com/aliqingge/p/9712474.html
java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory的解决 博客分类：问题ApacheJavaTomcatMyeclipse 自己前一段时间出现了这个问题，通过在网上搜索，大概知道了原因，整理下一，以供大家参考。
将项目部署好后，启动tomcat后报错，java.lang.NoClassDefFoundError:
org/apache/juli/logging/LogFactory 报这个错说明你用的是tomcat7。
目前的MyEclipse的内核为Eclipse3.5.* 尚不能提供直接对tomca...

首先在pom.xml中添加Apache Commons Exec的Maven坐标：<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-exec -->

java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource解决方法 只需把这三个commons-pool.jar、commons-dbcp-1.2.2.jar和commons-collections-3.2.jar包加入到lib里即可解决。这三个包在你本地的tomcat下的lib里，直接buildpath导入就行了，不过有时导包不一定好使，是因为工程lib下的包跟tomcat下的包重复了，导致异常错误如：org.apache.jasper.JasperException: java.lang.ClassCastException: org.apac...
首先肯定是版本出现了一点兼容问题所以我就进入项目，查看依赖树，cd到项目目录下，mvn dependency:tree我看到我的项目原先是1.5.9和现在2.0.1的区别在于org.slf4j的依赖不全【1.5.9.release】【2.0.1.release】那么问题简单了，我就把原先用到的日志依赖全部手动添加1.7.25版本<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclus...

spark1（默认CDH自带版本）不存在这个问题，主要是升级了spark2（CDHparcel升级）版本安装后需要依赖到spark1的旧配置去读取hadoop集群的依赖包。1./etc/spark2/conf目录需要指向/hadoop1/cloudera-manager/parcel-repo/SPARK2-2.1.0.cloudera1-1.cdh5.7.0.p0.120904/etc/spark2/conf.dist （命令ln -s /hadoop1/cloudera-manager/parcel-repo/SPARK2-2.1.0.cloudera1-1.cdh5.7.0.p0.120904/etc/spark2/conf.dist /etc/spark2/conf...
