Today i just tried to build my first web Java application. I follow the instructions from this link: https://docs.spring.io/spring-boot/docs/1.0.2.RELEASE/reference/html/getting-started-first-application.html
Everything looks good until i reach to step 10.4 , i got this error
[ERROR] Source option 6 is no longer supported. Use 7 or later.
[ERROR] Target option 6 is no longer supported. Use 7 or later.
Some recommend that we need to add this in to <project> tag
<properties>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.source>1.8</maven.compiler.source>
</properties>
It works for some people , but it’s not working for me. Finally i found that i need to add this
<properties>
<java.version>1.9</java.version>
</properties>
More detail is from this url: https://www.baeldung.com/maven-java-version
This is my final pom.xml
