Christoph Läubrich created MCOMPILER-524:
--------------------------------------------

             Summary: Please use usefull defaults
                 Key: MCOMPILER-524
                 URL: https://issues.apache.org/jira/browse/MCOMPILER-524
             Project: Maven Compiler Plugin
          Issue Type: Improvement
            Reporter: Christoph Läubrich


I have this absolute minimal pom:


{code:xml}
<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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>test</groupId>
  <artifactId>minimal</artifactId>
  <version>0.0.1-SNAPSHOT</version>
</project>
{code}

executing this with maven fails with:

{code:java}
[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] Source option 5 is no longer supported. Use 7 or later.
[ERROR] Target option 5 is no longer supported. Use 7 or later.
{code}

As I have configured nothing, as a user I would expect that the defaults are something that at least can work and do not fail, or gives a strong indication that some kind of configuration is required but missing. In this case it would even be appropriate to instead have an error to issue a warning that level 7 is used instead.
