IntelliJ IDEA 配合 Maven 的一些技巧
IntelliJ IDEA 2017.1
Maven 3.3.9
Nexus 3.2.1
了解 Maven 配置的基本用法
了解私有仓库,比如 nexus 的一些概念
强烈建议把 Maven 的 settings.xml 文件同时放在:%USER_HOME%/.m2/settings.xml
和 ${maven.home}/conf/settings.xml
两个地方。避免使用终端的时候默认去调用用户目录下的
Maven 中有一个概念叫做:profile
,它的诞生主要是为了解决不同环境所需的不同变量、配置等问题。
有了 profile,可以根据激活的条件,启动不同条件下的配置信息。
profile 是可以有多个的,也可以同时激活多个 profile,方便自由组合。
profile 一般可以在三个地方:settings.xml,pom.xml,profiles.xml(这个不常用)
在 settings.xml 上,一般大家用来做仓库的选择,比如以下 settings.xml 代码:
<?xml version =" 1.0" encoding =" UTF-8" ?>
<settings xmlns =" http://maven.apache.org/SETTINGS/1.0.0"
xmlns : xsi =" http://www.w3.org/2001/XMLSchema-instance"
xsi : schemaLocation =" http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd" >
<localRepository >D:\maven\my_local_repository</localRepository >
<pluginGroups >
</pluginGroups >
<proxies >
</proxies >
<profiles >
<profile >
<id >nexus</id >
<repositories >
<repository >
<id >nexus</id >
<url >http://192.168.1.73:8081/repository/maven-public/</url >
<releases >
<enabled >true</enabled >
</releases >
<snapshots >
<enabled >true</enabled >
</snapshots >
</repository >
</repositories >
<pluginRepositories >
<pluginRepository >
<id >nexus</id >
<url >http://192.168.1.73:8081/repository/maven-public/</url >
<releases >
<enabled >true</enabled >
</releases >
<snapshots >
<enabled >true</enabled >
</snapshots >
</pluginRepository >
</pluginRepositories >
</profile >
<profile >
<id >aliyun</id >
<repositories >
<repository >
<id >aliyun</id >
<url >http://maven.aliyun.com/nexus/content/groups/public/</url >
<releases >
<enabled >true</enabled >
</releases >
<snapshots >
<enabled >true</enabled >
</snapshots >
</repository >
</repositories >
<pluginRepositories >
<pluginRepository >
<id >aliyun</id >
<url >http://maven.aliyun.com/nexus/content/groups/public/</url >
<releases >
<enabled >true</enabled >
</releases >
<snapshots >
<enabled >true</enabled >
</snapshots >
</pluginRepository >
</pluginRepositories >
</profile >
</profiles >
<activeProfiles >
<activeProfile >nexus</activeProfile >
</activeProfiles >
</settings >
以上代码中 profile 就做一件事:设置全局的 profile,一个是 nexus 仓库,一个是 aliyun 仓库,默认激活的是 nexus 仓库。(activeProfiles)
在 pom.xml 中,一般用来激活环境配置,比如以下代码:
<profiles >
<profile >
<id >dev</id >
<properties >
<package .environment>dev</package .environment>
</properties >
<activation >
<activeByDefault >true</activeByDefault >
</activation >
<build >
<resources >
<resource >
<directory >src/main/resources</directory >
<includes >
<include >**/*</include >
</includes >
<filtering >true</filtering >
</resource >
<resource >
<directory >src/main/env/${package.environment}</directory >
<includes >
<include >**/*</include >
</includes >
<filtering >true</filtering >
</resource >
</resources >
<finalName >${project.artifactId}</finalName >
</build >
</profile >
<profile >
<id >product</id >
<properties >
<package .environment>product</package .environment>
</properties >
<activation >
<activeByDefault >false</activeByDefault >
</activation >
<build >
<resources >
<resource >
<directory >src/main/resources</directory >
<includes >
<include >**/*</include >
</includes >
<filtering >true</filtering >
</resource >
<resource >
<directory >src/main/env/${package.environment}</directory >
<includes >
<include >**/*</include >
</includes >
<filtering >true</filtering >
</resource >
</resources >
<finalName >${project.artifactId}</finalName >
</build >
</profile >
</profiles >
以上代码中 profile 就做一件事:打包的时候,默认是 dev 模式,打包 src/main/env/dev 下的配置文件,如果选择 product 则打包 src/main/env/product 下的配置文件
IntelliJ IDEA 使用 Maven Profile 的案例
在 IntelliJ IDEA 上调用 profile 简单,如下图勾选对应的复选框即可,可以多选。
只使用 aliyun 仓库可以这样配置 settings.xml:
<?xml version =" 1.0" encoding =" UTF-8" ?>
<settings xmlns =" http://maven.apache.org/SETTINGS/1.0.0"
xmlns : xsi =" http://www.w3.org/2001/XMLSchema-instance"
xsi : schemaLocation =" http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd" >
<localRepository >D:\maven\my_local_repository</localRepository >
<pluginGroups >
</pluginGroups >
<proxies >
</proxies >
<profiles >
<profile >
<id >aliyun</id >
<repositories >
<repository >
<id >aliyun</id >
<url >http://maven.aliyun.com/nexus/content/groups/public/</url >
<releases >
<enabled >true</enabled >
</releases >
<snapshots >
<enabled >true</enabled >
</snapshots >
</repository >
</repositories >
<pluginRepositories >
<pluginRepository >
<id >aliyun</id >
<url >http://maven.aliyun.com/nexus/content/groups/public/</url >
<releases >
<enabled >true</enabled >
</releases >
<snapshots >
<enabled >true</enabled >
</snapshots >
</pluginRepository >
</pluginRepositories >
</profile >
</profiles >
<activeProfiles >
<activeProfile >aliyun</activeProfile >
</activeProfiles >
</settings >
使用 nexus + aliyun 仓库可以这样配置 settings.xml:
<?xml version =" 1.0" encoding =" UTF-8" ?>
<settings xmlns =" http://maven.apache.org/SETTINGS/1.0.0"
xmlns : xsi =" http://www.w3.org/2001/XMLSchema-instance"
xsi : schemaLocation =" http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd" >
