Why does Maven/Eclipse think Java 1.11 is earlier than 1.7?
0
I want to start using JDK 11 in a project that was previously developed on JDK 8.
I have the latest Eclipse IDE (Photon).
So I changed this from 1.8 to 1.11 in the project's pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.11</source>
<target>1.11</target>
</configuration>
</plugin>
And now I get the error:
'<>' operator is not allowed for source level below 1.7
Apparently Maven and/or Eclipse are not interpreting 1.11 correctly.
How to fix?

For your information, there is no such thing as Java 1.11

Use this then run Maven -> Update, ensure Eclipse version is at least 18-09, and also manually change the JDK level in Eclipse after doing this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<release>11</release>
</configuration>
</plugin>

@AlexR What version of Eclipse Photon do you have? Only Eclipse 2018-09 does have Java 11 support.

Just upgrading didn't work either... I had to change the JDK level directly in the Eclipse config (something Maven should have handled for me?)
