mvn compile throws errors

Hello,

I’m working on this guide, but when I run mvn compile I get the following error:

[ERROR] Source option 1.5 is no longer supported. Use 1.6 or later.
[ERROR] Target option 1.5 is no longer supported. Use 1.6 or later.

I’m on OS X. mvn -v shows:

Maven home: /Users/matthuntington/Desktop/apache-maven-3.5.0
Java version: 9, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.12.6", arch: "x86_64", family: "mac"

echo $JAVA_HOME shows:

/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home

echo $PATH shows:

/Users/matthuntington/Desktop/apache-maven-3.5.0/bin/:/Users/matthuntington/.rbenv/bin:/Users/matthuntington/.rbenv/shims:/Users/matthuntington/anaconda/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin

any suggestions? Thanks!

Solution: I added

<properties>
    <maven.compiler.source>1.6</maven.compiler.source>
    <maven.compiler.target>1.6</maven.compiler.target>
  </properties>

inside the project tag in pom.xml

<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
 </properties>
