Centos7 maven 安装

maven 下载省略

sudo mkdir -p /usr/local/maven

tar -zxvf apache-maven-3.9.10-bin.tar.gz -C /usr/local/maven/

/usr/local/maven/apache-maven-3.9.10/bin

sudo vi /etc/profile.d/maven.sh

export JAVA_HOME=/usr/lib/jvm/jdk-17

export M2_HOME=/usr/local/maven/apache-maven-3.9.10

export MAVEN_HOME=/usr/local/maven/apache-maven-3.9.10

export PATH={M2_HOME}/bin:{PATH}

source /etc/profile

或者重新登录

mvn -version

代码中使用时，在pom.xml中配置

jdk 8 版本

<build>

<plugins>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<version>3.8.1</version>

<configuration>

<source>1.8</source>

<target>1.8</target>

<fork>true</fork>

<artifactId>maven-compiler-plugin</artifactId>

<version>3.11.0</version>

<configuration>

<source>17</source>

<target>17</target>

<fork>true</fork>

<executable>${JAVA_HOME}/bin/javac</executable>

<encoding>UTF-8</encoding>

</configuration>

</plugin>

</plugins>

</build>

完整配置（包含编译器参数）

<build>

<plugins>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<version>3.11.0</version>

<configuration>

<source>17</source>

<target>17</target>

<fork>true</fork>

<executable>${JAVA_HOME}/bin/javac</executable>

<encoding>UTF-8</encoding>

<compilerArgs>

<arg>-parameters</arg>

<arg>-Xlint:unchecked</arg>

<arg>-Xlint:deprecation</arg>

</compilerArgs>

<showWarnings>true</showWarnings>

<showDeprecation>true</showDeprecation>

</configuration>

</plugin>

</plugins>

</build>

多版本兼容配置（如果需要）

<build>

<plugins>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<version>3.11.0</version>

<configuration>

<source>17</source>

<target>17</target>

<fork>true</fork>

<executable>${env.JAVA_HOME_17}/bin/javac</executable>

<compilerArgs>

<!-- 启用预览特性（如果需要） -->

<!-- <arg>--enable-preview</arg> -->

</compilerArgs>

<encoding>UTF-8</encoding>

</configuration>

</plugin>

</plugins>

</build>

属性方式配置

<properties>

<maven.compiler.source>17</maven.compiler.source>

<maven.compiler.target>17</maven.compiler.target>

<maven.compiler.compilerVersion>17</maven.compiler.compilerVersion>

<maven.compiler.fork>true</maven.compiler.fork>

<maven.compiler.executable>${JAVA_HOME}/bin/javac</maven.compiler.executable>

</properties>

<build>

<plugins>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<version>3.11.0</version>

</plugin>

</plugins>

</build>

推荐使用第一种基本配置，除非你有特殊需求需要指定具体的JDK路径
