maven常用命令
环境变量配置
1、确认JAVA_HOME 环境变量配置eg:C:\Program Files\Java\jdk1.8.0_102
2、配置MAVEN_HOME 环境变量配置eg:C:\adeng\soft\apache-maven-3.3.9
3、新增Path变量 eg:%MAVEN_HOME%\bin
配置本地仓库地址：
在形如：C:\adeng\soft\apache-maven-3.3.9\conf 目录下编辑setting.xml 搜索 localrepository 关键字
<localRepository>/path/to/local/repo</localRepository> 相对路径，相对于maven安装的磁盘
<localRepository>c:/path/to/local/repo</localRepository>指定磁盘和路径

安装jar到本地仓库：mvn install:install-file -DgroupId=pinyin4clj -DartifactId=pinyin4clj -Dversion=0.3.0 -Dpackaging=jar -Dfile=E:\tmp\pinyin4clj-0.3.0.jar -DgeneratePom=true
安装jar到项目：mvn install:install-file -DgroupId=com.imooc.maven -DartifactId=maven01 -Dversion=1.0-SNAPSHOT -Dpackaging=jar -Dfile=D:\java\m2\repository\com\imooc\maven\maven01\1.0-SNAPSHOT\maven01-1.0-SNAPSHOT.jar -DgeneratePom=true -DlocalRepositoryPath=C:\adeng\work\kukii\corejava\src\main\resources\lib2\
maven 构建框架慢 添加 archetypeCatalog=internal
查看maven版本：mvn -version
怎么查看maven本地仓库地址: mvn help:effective-settings
查看激活的profile：mvn help:active-profiles
激活指定的profile：mvn -P dev package
filtering using resources:http://maven.apache.org/plugins/maven-resources-plugin/examples/filter.html
指定不filter的二进制文件：http://maven.apache.org/plugins/maven-resources-plugin/examples/binaries-filtering.html
Getting a report of dependencies:(Apache Maven Cookbook chapter5)
mvn dependency:list
mvn dependency:tree
Getting into dependency and avoiding dependency hell:
mvn dependency:tree
Downloading dependencies into a folder:(download dependencies in the target/dependency folder)
mvn dependency:copy-dependencies
mvn dependency:copy-dependencies -DoutputDirectory=target/dependencies --change to the designation folder
mvn dependency:copy-dependencies -Dmdep.copyPom=true -Dmdep.useRepositoryLayout=true ---keep the folder layout
detect the unused/undeclared dependencies:
mvn dependency:analyze
Chapter6：Code Quality Plugins
jacoco：
若没有生成测试报告（${basedir}/target/site/jacoco） 请确保maven-surefire-plugin 的 skipTests = true
若遇到如下错误，说明二进制文件被损坏了，如下错误
java.util.zip.ZipException: invalid literal/length code in JacocoPublisher
大神的解决方案：http://www.cnblogs.com/llxrl/p/5884978.html
原因：maven从resources中读取资源时默认会进行过滤，其中包含了重新编码，因此如果资源文件与maven的编码环境不同时，会导致文件损坏。
解决：（方案1）在pom.xml中设置filtering为true时则过滤
<filtering>true</filtering>
因此将其置false。
（方案2）将maven-resources-pligin中的encoding改为源文件的编码方式，这个比较复杂，因为我们有时候不知道源文件的编码方式，尤其是在使用第三方jar的时候
<encoding>源文件的编码方式（比如IS0-8859-1）</encoding>
（方案3）把资源文件zip解压后放入resources，但是要是二进制文件的话这招也不好使
我的终极解决方案：（指定二进制类型不被过滤，一劳永逸）
1 <plugin> 2 <groupId>org.apache.maven.plugins</groupId> 3 <artifactId>maven-resources-plugin</artifactId> 4 <version>3.0.2</version> 5 <configuration> 6 <encoding>UTF-8</encoding> 7 <resources> 8 <resource> 9 <directory>${basedir}/src/main/resources</directory> 10 </resource> 11 <resource> 12 <directory>${basedir}/src/main/resources</directory> 13 <includes> 14 <include>*.properties</include> 15 </includes> 16 <filtering>true</filtering>//这只指定过滤的文件类型，把影响降低到最小 17 </resource> 18 <resource> 19 <directory>${basedir}/src/main/java</directory> 20 <includes> 21 <include>**/*.properties</include> 22 </includes> 23 </resource> 24 </resources> 25 <!--指定替换文件的原文件--> 26 <filters> 27 <filter>${basedir}/src/main/resources/my-filter-values.properties</filter> 28 </filters> 29 <nonFilteredFileExtensions> 30 <nonFilteredFileExtension>jar</nonFilteredFileExtension> //指定jar文件不被过滤，当然也可以添加其他的二进制文件 31 </nonFilteredFileExtensions> 32 </configuration> 33 </plugin>
另：插件生成测试类http://www.cnblogs.com/adeng/p/7181418.html
cobertura：
mvn cobertura:cobertura
可设置测试代码覆盖率低于多少自动失败，下面的设置是，测试代码覆盖率低于85%自动失败
命令：mvn cobertura:check
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>

PMD：
mvn pmd:pmd pmd:cpd
Copy/Paste Detector(CPD) that finds duplicated code.
发现重复代码利器
CheckStyle：
mvn checkstyle:checkstyle
FindBugsy：
mvn clean compile findbugs:findbugs
Generating source references with Maven JXR Plugin:
mvn jxr:jxr
the jxr generates the cross-reference ,Once the cross reference exists.code quality tools, such as PMD and CheckStyle,link to this reference automatically by using the following steps:
mvn jxr:jxr checkstyle:checkstyle
SonarQube：
这个最牛逼
1、下载：https://www.sonarqube.org/downloads/
2、解压安装启动，访问默认网址：http://localhost:9000
Use the following step to analyze the code with the Maven SonarQube plugin:
mvn sonar:sonar
Chapter7：Reporting and Documentation
Documenting with the Maven Site plugin：
mvn site
用到的插件：
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-project-info-reports-plugin</artifactId> <version>2.9</version> </plugin>
Generating Javadoc for a Site：
mvn site
用到的插件：
<reporting> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-javadoc-plugin</artifactId> <version>2.10.4</version> <configuration> <charset>UTF-8</charset> <encoding>UTF-8</encoding> <docencoding>UTF-8</docencoding> </configuration> </plugin> </plugins> </reporting>
若输出到控制台的信息乱码：
做如下配置：
哎，命运多舛，一直折腾。
另，idea自带的也有生成javadoc的工具：Tools-->Generate JavaDoc
乱码处理：Other command line arguments 中填写：-encoding utf-8 -charset utf-8 但是没有maven-javadoc-plugin输出的信息详细。
Generating source cross-reference for a site：
1、 add the following code to the reporting section of pom.xml file:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jxr-plugin</artifactId> <version>2.5</version> <reportSets> <reportSet> <id>aggregate</id> <reports> <report>aggregate</report> <!--是否生成测试源码引用--> <!--<report>test-aggregate</report>--> </reports> </reportSet> </reportSets> </plugin>
注：若使用阿里云仓库，贴入上面的代码后，maven可能不识别，做法是先在dependencis 中贴入jar包的依赖，下载jar后就可以了。
Generting unit test reports for a site：
1、 add the following code to the reporting section of pom.xml file:
