Change JDK in Maven Projects (Eclipse)

Java Sep 19, 2018

New Maven projects created in Eclipse use the default JRE System Library "J2SE-1.5". If you want to use a newer version, change your pom.xml like this.

<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>

For Java10:

<properties>
	<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	<maven.compiler.source>10</maven.compiler.source>
	<maven.compiler.target>10</maven.compiler.target>
</properties>
