在pom里添加maven-compiler-plugin插件版本信息，无法识别plugins标签-CSDN问答

maven配置私服打包报错Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5:compile

直接使用阿里云镜像仓库打包没问题，替换为私服镜像仓库后报错：就是pom.xml中的plugin报错 ``` <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.5</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> ``` 网上找了半天说这个指定的jdk版本的问题，查了一下版本没问题都是1.8 报错内容： [ERROR] Failed to execute goal

maven3 2个问题求解答网上搜不到

1. maven的内置插件是在哪里定义的有哪些内置插件看了源码里的主pom，只有以下插件 ``` - <pluginManagement> -  -  - <plugins> - <plugin> <artifactId>maven-antrun-plugin</artifactId> <version>1.3</version> </plugin> - <plugin> <artifactId>maven-assembly-plugin</artifactId> <version>2.2-beta-5</version> </plugin> - <plugin> <artifactId>maven-dependency-plugin</artifactId> <version>2.8</version> </plugin> - <plugin> <artifactId>maven-release-plugin</artifactId> <version>2.3.2</version> </plugin> </plugins> </pluginManagement> ``` 2、我在我自己的父pom里声明了插件 ``` <pluginManagement> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.3.2</version> <configuration> <source>1.6</source> <target>1.6</target> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <version>2.5</version> <configuration> <useDefaultDelimiters>false</useDefaultDelimiters> <delimiters> <delimiter>$[*]</delimiter> </delimiters> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.owasp</groupId> <artifactId>dependency-check-maven</artifactId> <executions> <execution> <goals> <goal>check</goal> </goals> </execution> </executions> <configuration> <format>xml</format> </configuration> </plugin> </plugins> </pluginManagement> ``` 但我在其他子模块中并没有用这些插件，但是这些插件还是起作用了，为什么？

在控制台上maven打包报错。

楼主刚看徐晓斌的《maven实战》，正在控制台上鼓捣maven呢，mvn clean compile,mvn clean test也成功，然后mvn clean package打包也成功，但是由于打出来的Jar包没有指定main方法的位置，我就按照书上的案例，加入maven-shade-plugin插件，在pom.xml加入这话话，一直打包都是错误的。 pom.xml文件配置如下: ``` <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>xx.xx.xxx</groupId> <artifactId>hello-maven</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>1.2.1</version> <configuration> <transformers> <transformer implementation = "org.apache.maven.plugins.shade.resource.MainifestResourceTransformer"> <mainClass>xx.xxx.xxx.hellomaven.App</mainClass> </transformer> </transformers> </configuration> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </project> ``` 控制台报错信息如下： ``` [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 1.731s [INFO] Finished at: Tue Mar 29 11:40:17 CST 2016 [INFO] Final Memory: 10M/24M [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:1.2.1 :shade (default) on project hello-maven: Unable to parse configuration of mojo o rg.apache.maven.plugins:maven-shade-plugin:1.2.1:shade: ClassNotFoundException: Class name which was explicitly given in configuration using 'implementation' at tribute: 'org.apache.maven.plugins.shade.resource.MainifestResourceTransformer' cannot be loaded -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e swit ch.

比特币原理详解

一、什么是比特币比特币是一种电子货币，是一种基于密码学的货币，在2008年11月1日由中本聪发表比特币白皮书，文中提出了一种去中心化的电子记账系统，我们平时的电子现金是银行来记账，因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述，这一层面介绍的文章很多，本文主要从更深层的技术原理角度进行介绍。二、问题引入假设现有4个人

程序员接私活怎样防止做完了不给钱？

首先跟大家说明一点，我们做 IT 类的外包开发，是非标品开发，所以很有可能在开发过程中会有这样那样的需求修改，而这种需求修改很容易造成扯皮，进而影响到费用支付，甚至出现做完了项目收不到钱的情况。那么，怎么保证自己的薪酬安全呢？我们在开工前，一定要做好一些证据方面的准备（也就是“讨薪”的理论依据），这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发
