Description

Failure on Java 10 in Windows:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project mng-6127-plugin: Compilation failure
[ERROR] /D:/Entwicklung/Projekte/maven-integration-testing/core-it-suite/target/test-classes/mng-6127-plugin-execution-configuration-interference/plugin/src/main/java/org/apache/maven/its/mng6127/plugin/TestMojo.java:[67,13] try-with-resources is not supported in -source 6
[ERROR]   (use -source 7 or higher to enable try-with-resources)
[ERROR] -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project mng-6127-plugin: Compilation failure

The compiled plugin uses Java 7, but the code introduced in ee3cae93ce70f9ff1898b5c10f3cce59898923af autoresets everything to 1.6.

Drop all occurencies of maven.compiler.* and remove the try-with-resources statement.
