在Maven项目(Eclipse)中更改JDK [英] Change JDK in Maven Projects (Eclipse)

问题描述

新的 Maven 项目使用默认的JRE系统库"J2SE-1.5".

New Maven projects created in Eclipse (on Windows) use the default JRE System Library "J2SE-1.5".

Maven项目中的默认系统库

该项目是通过以下方式创建的:

The project was created the following way:

• 新项目
• Maven-> Maven项目
• Archtype:maven-archetype-quickstart

我想使用 JDK 1.8.0 ，这是非Maven项目的默认JDK.

我的 JAVA_HOME 变量设置为

I want to use the JDK 1.8.0, which is my default JDK for non Maven projects.

My JAVA_HOME variable is set to

C:\ Program Files \ Java \ jdk1.8.0_152

C:\Program Files\Java\jdk1.8.0_152

我尝试通过右键单击系统库来切换系统库，并将路径设置为我的 JDK 1.8.0 .但是在Maven更新之后，它会重置为1.5.

I tried switching the system library via Right Click on the System Library and set the path to my JDK 1.8.0. But after a Maven update it resets back to the 1.5.

其他Stackoverflow问题仅建议设置JAVA_HOME，但这对我不起作用.指定供Maven使用的JDK

我寻找了一些 POM.xml 命令来设置库，但是找不到任何东西.我的POM现在看起来很标准:

Other Stackoverflow questions just suggest to set the JAVA_HOME, but that did not work for me. Specify JDK for Maven to use

I looked for some POM.xml commands to set the library, but couldn't find anything. My POM looks pretty standard right now:

<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>4.0.0</modelVersion>

<groupId>com.test</groupId>
<artifactId>Test123</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

<name>Test123</name>
<url>http://maven.apache.org</url>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>3.8.1</version>
        <scope>test</scope>
    </dependency>
</dependencies>

要使JDK 1.8成为默认库，我需要更改什么?

What do I need to change to get the JDK 1.8 as my default Library?

推荐答案

在pom.xml中设置JDK:

Set the JDK in the pom.xml:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

在Eclipse中执行"Maven->更新项目"

in eclipse do a 'Maven->Update Project'
