Maven运行命令随记

注意本文是基于linux 的记录

· Maven在运行命令中设置代理

mvn -B -DproxySet=true -Dhttp.proxyHost=proxy_host -Dhttp.proxyPort=1080 -Dhttp.nonProxyHosts="nonproxy.com|nonproxy.net:8080" package

Relation article

https://stackoverflow.com/questions/1251192/how-do-i-use-maven-through-a-proxy

该帖子中还会提到另一种设置http proxy以及socket proxy的参数，仅供参考，有待验证

· 使用Maven向Nexus upload jar包

mvn deploy:deploy-file -DgroupId={groupId} -DartifactId={artifactId} -Dversion={version} -Dpackaging=jar -Dfile=/jar-path.jar -Durl=http://nexus/repository/maven-uploaded-url

如果nexus有密码认证的话则需要-DrepositoryId=参数调用写在了settings.xml文件中servers段内的账号密码进行认证

mvn deploy:deploy-file -DgroupId={groupId} -DartifactId={artifactId} -Dversion={version} -Dpackaging=jar -Dfile=/jar-path.jar -DrepositoryId=nexus -Durl=http://nexus/repository/maven-uploaded-url

注意mvn deploy-file不支持上传处于本地repo中的jar包，即: Cannot deploy artifact from the local repository

需要将 ~/.m2/repository 中相应的jar包提前cp出来再进行deploy

使用Maven向Nexus 批量 upload jar 包

原脚本内容:

#!/bin/sh

# Reference: http://roboojack.blogspot.in/2014/12/bulk-upload-your-local-maven-artifacts.html

if [ "$#" -ne 3 ] || ! [ -d "$1" ]; then
    echo "Usage:"
    echo "       bash run.sh <repoRootFolder> <repositoryId> <repositoryUrl>"
    echo ""
    echo ""
    echo "       Where..."
    echo "       repoRootFolder: The folder containing the repository tree."
    echo "                       Ensure you move the repository outside of ~/.m2 folder"
    echo "                       or whatever is configured in settings.xml"
    echo "       repositoryId:   The repositoryId from the <server> configured for the repositoryUrl in settings.xml."
    echo "                       Ensure that you have configured username and password in settings.xml."
    echo "       repositoryUrl:  The URL of the repository where you want to upload the files."
    exit 1
fi

while read -r line ; do
    echo "Processing file $line"
    pomLocation=${line/./}
    pomLocation=$PWD${pomLocation/jar/pom}
    jarLocation=${line/./}
    jarLocation=$PWD${jarLocation/pom/jar}
    #echo $pomLocation
    #echo $jarLocation
    mvn deploy:deploy-file -DpomFile=$pomLocation -Dfile=$jarLocation -DrepositoryId=$2 -Durl=$3
done < <(find $1 -name "*.jar")

该脚本解析location似乎有问题，改了一下

#!/bin/sh

# Reference: http://roboojack.blogspot.in/2014/12/bulk-upload-your-local-maven-artifacts.html

if [ "$#" -ne 3 ] || ! [ -d "$1" ]; then
    echo "Usage:"
    echo "       bash run.sh <repoRootFolder> <repositoryId> <repositoryUrl>"
    echo ""
    echo ""
    echo "       Where..."
    echo "       repoRootFolder: The folder containing the repository tree."
    echo "                       Ensure you move the repository outside of ~/.m2 folder"
    echo "                       or whatever is configured in settings.xml"
    echo "       repositoryId:   The repositoryId from the <server> configured for the repositoryUrl in settings.xml."
    echo "                       Ensure that you have configured username and password in settings.xml."
    echo "       repositoryUrl:  The URL of the repository where you want to upload the files."
    exit 1
fi

while read -r line ; do
    echo "Processing file $line"
    Location=${line/.jar}
    pomLocation=${Location}.pom
    jarLocation=${Location}.jar
    echo $pomLocation
    echo $jarLocation
    mvn deploy:deploy-file -DpomFile=$pomLocation -Dfile=$jarLocation -DrepositoryId=$2 -Durl=$3
done < <(find $1 -name "*.jar")

使用命令 bash script.sh m2 nexus "http://nexus/repo" 开始冲冲冲

· Maven : test skip

-Dmaven.test.skip=true

· Maven plugin: SonarQube

simple documentation

jacoco 需要在sonarqube server提前安装

# sonar-scanner documents: docs.sonarqube.org/latest/analysis/analysis-parameters
# Environment variable description：
#   SONAR_LOGIN: SonarQube Token
#   SONAR_HOST_URL: SonarQube Homepage URL
#   SONAR_PROJECT_KEY: SonarQube Project Key
#   SONAR_SOURCES: Directory to be analyzed
#   SONAR_JAVA_BINARIES: Comma-separated paths to directories containing the compiled bytecode files corresponding to your source files.
# Jacoco unit test:
#  -Dsonar.java.covergaePlugin=jacoco
#  -Dsonar.jacoco.reportPaths=target/jacoco.exec

jacoco是一个开源的覆盖率工具，针对java语言

适用于单元覆盖率验证，通常要求单元覆盖率不低于60%。

JaCoCo优势：

　　　　(1) JaCoCo支持分支覆盖、引入了Agent模式。

　　　　(2) EMMA官网已经不维护了，JaCoCo是其团队开发的，可以理解为一个升级版。

　　　　(3) JaCoCo社区比较活跃，官网也在不断的维护更新。

Jacoco可以嵌入到Ant 、Maven中，并提供了EclEmma Eclipse插件,也可以使用JavaAgent技术监控Java程序。很多第三方的工具提供了对Jacoco的集成，如sonar、Jenkins等。

Jacoco包含了多种尺度的覆盖率计数器,包含指令级覆盖(Instructions,C0coverage)，分支(Branches,C1coverage)、圈复杂度(CyclomaticComplexity)、行覆盖(Lines)、方法覆盖(non-abstract methods)、类覆盖(classes)

指定SonarQube plugin版本

mvn package org.sonarsource.scanner.maven:sonar-maven-plugin:3.6.0.1398:sonar \
  -Dsonar.projectKey=$SONAR_PROJECT_KEY \
  -Dsonar.host.url=$SONAR_HOST_URL \
  -Dsonar.login=$SONAR_LOGIN \
  -Dsonar.sources=$SONAR_SOURCES \
  -Dsonar.java.binaries=$SONAR_JAVA_BINARIES \
  -Dsonar.exclusions=$SONAR_EXCLUSIONS 

sonar.verbose

-Dsonar.verbose=true

scm disable （disable git or svn scanning）

错误信息如下:

[ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.6.0.1398:sonar (default-cli) on project dep: Not inside a Git work tree: /path -> [Help 1]

解决手段1:

指定Base路径

-Dsonar.projectBaseDir

解决手段2:

直接关闭git/svn扫描

-Dsonar.scm.disabled=true

can't be indexed twice

错误信息类似如下:

[ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.8.0.2131:sonar (default-cli) on project project-name: File project-dir/src/test/java/com/groupid/project/service/SpotPlanScheduleServiceTest.java can't be indexed twice. Please check that inclusion/exclusion patterns produce disjoint sets for main and test files -> [Help 1]

[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException

解决手段,调整扫描目录以及忽略扫描目录

并且扫描与忽略目录不能相交:

sonar.sources=.
sonar.tests=.
sonar.test.inclusions=**/*Test*/**
sonar.exclusions=**/*Test*/**
