Maven 项目配置使用备忘录

  1. 创建 Maven 项目:
 mvn archetype:generate -DgroupId=com.ivandu -DartifactId=cmaimms -DarchetypeArtifactImaven-archetype-quickstart -DinteractiveMode=false

命令解释:

  • -DgroupId 组织Id(项目包名)。
  • -DartifactId ArtifactId(项目名称或者模块名称)。
  • -DarchetypeArtifactId 项目骨架。
  • -DinteractiveMode 是否使用交互模式。
  1. “File encoding has not been set, using platform encoding UTF-8” 问题解决:

IDE 字符编码设置为:UTF-8, IDEA 自定义环境加入:

-Dfile.encoding=utf-8

项目 pom.xml 加入:

  <properties>
    <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>
  properties>
  1. “No goals have been specified for this build.” 问题解决:

项目 pom.xml 加入:

<build>
    <defaultGoal>compiledefaultGoal>
build>
  1. “[ERROR] 不再支持源选项 5。请使用 6 或更高版本。[ERROR] 不再支持目标选项 1.5。请使用 1.6 或更高版本。” 问题解决:
<properties>
    <java.version>11java.version>
    <maven.compiler.source>11maven.compiler.source>
    <maven.compiler.target>11maven.compiler.target>
properties>
  1. mvn spring-boot:run 报 “No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?” 错,解决如下:

在项目 pom.xml build 节点内加入:

<plugin>
  <groupId>org.apache.maven.pluginsgroupId>
  <artifactId>maven-compiler-pluginartifactId>
  <version>3.8.1version>
  <configuration>
    <verbose>trueverbose>
    <fork>truefork>
    <executable>D:\Tools\Java\jdk-11.0.12.7-hotspot\bin\javac.exeexecutable>
  configuration>
plugin>
  1. 一些常用配置:
<properties>
        <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8project.reporting.outputEncoding>
        <java.version>1.8java.version>
properties>
  1. 指定 JDK 版本、字符集配置:
<profile>
    <id>jdk-11id>
    <activation>
        <activeByDefault>trueactiveByDefault>
        <jdk>11jdk>
    activation>
    <properties>
        <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>
        <maven.compiler.source>11maven.compiler.source>
        <maven.compiler.target>11maven.compiler.target>
        <maven.compiler.compilerVersion>11maven.compiler.compilerVersion>
    properties>
profile>
  1. Maven 阿里云公共仓库:
<mirror>
    <id>aliyunmavenid>
    <mirrorOf>*mirrorOf>
    <name>阿里云公共仓库name>
    <url>https://maven.aliyun.com/repository/publicurl>
mirror>
  1. 无法读取配置文件,可以加入如下内容:
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.pluginsgroupId>
            <artifactId>maven-compiler-pluginartifactId>
            <version>3.8.0version>
            <configuration>
                <source>11source>
                <target>11target>
            configuration>
        plugin>
    plugins>
    <resources>
        <resource>
            <directory>src/main/javadirectory>
            <includes>
                <include>**/*.xmlinclude>
                <include>**/*.propertiesinclude>
            includes>
            <filtering>falsefiltering>
        resource>
        <resource>
            <directory>src/main/resourcesdirectory>
            <includes>
                <include>**/*.*include>
                <include>**/*.propertiesinclude>
            includes>
            <filtering>falsefiltering>
        resource>
    resources>
build>
  1. Maven scope 元素用于指定依赖库起作用的范围。该元素可指定如下值:

➢ compile:默认的范围,编译、测试、打包时需要。
➢ provided:表示容器会在运行时提供。
➢ runtime:表示编译时不需要,但测试和运行时需要,最终打包时会包含进来。
➢ test:只用于测试阶段。
➢ system:与provided类似,但要求该JAR是系统自带的。

11、Java执行Jar包报“jar中没有主清单属性”的解决方法:

<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>4.0.0modelVersion>

    <url>https://maven.apache.orgurl>

    <properties>
