maven项目编译jdk版本更改
首先要下载
maven-compiler-plugin jar包
通过maven-compiler-plugin jar包指定JDK版本和编码
方法1
在maven项目的pom.xml中加入一下代码
-
<build>
-
<plugins>
-
<plugin>
-
<groupId>org.apache.maven.plugins
groupId>
-
<artifactId>maven-compiler-plugin
artifactId>
-
<version>2.1
version>
-
<configuration>
-
<source>1.7
source>
-
<target>1.7
target>
-
configuration>
-
plugin>
-
plugins>
-
build>
然后重新update maven就可以解决该问题
方法2
修改maven配置文件
-
<profile>
-
<id>jdk-1.8
id>
-
<activation>
-
<activeByDefault>true
activeByDefault>
-
<jdk>1.8
jdk>
-
activation>
-
<properties>
-
<maven.compiler.source>1.8
maven.compiler.source>
-
<maven.compiler.target>1.8
maven.compiler.target>
-
<maven.compiler.compilerVersion>1.8
maven.compiler.compilerVersion>
-
properties>
-
profile>
然后刷新
先右键项目 选择maven选项add plugin
搜索compiler 选最新的
然后强制更新项目
