I’m trying to install dependendies using mvn install

I tried to find solution on stackoverflow but for now I still get same error
What I’ve tried :
- Changing level language 2.Adding properties to pom.xml file
Other solution that I’ve found involves other type of IDE
Here is my pom.xml file:
<?xml version="1.0" encoding="UTF-8"?> <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>groupId</groupId> <artifactId>untitled1</artifactId> <version>1.0-SNAPSHOT</version> <properties> <maven.compiler.source>11</maven.compiler.source> <maven.compiler.target>11</maven.compiler.target> </properties> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> </project>
I’m new to Maven and if you know any solutions tha I haven’t tried please comment down below. I will be thankfull for your answers
Edit: I’m using apache.maven.3.8.1
Answer
Install Java 1.8 (JDK) and configure JAVA_HOME
environment variable to point to the installation home of this Java version. You may need to logout/login or reboot for the environment variable change to have effect.
Maven will use it for compilation and will be able to target 1.6 version.
Java 11+ versions no longer support 1.6 target.
In IntelliJ IDEA it can be controlled here:
- Settings (Preferences on macOS) | Build, Execution, Deployment | Build Tools | Maven | Importing | JDK for importer
- Settings (Preferences on macOS) | Build, Execution, Deployment | Build Tools | Maven | Runner | JRE
