-------------------------------
Summary: Maven compiler ignores the configured target version
settings when higher JDK is installed
Key: MNG-6664
URL: https://issues.apache.org/jira/browse/MNG-6664
Project: Maven
Issue Type: Bug
Components: core
Affects Versions: 3.5.2
Environment: Windows 10 64bit
openJDK 11.0.1
Maven 3.5.2
Reporter: Jason Reed
I have an Open JDK 11 installed on my system and it is configured properly
through JAVA_HOME. I'm using Maven 3.5.2 to perform compiling via command line
and through my Eclipse IDE.
I have a project that where I have configured the maven.compiler.source and
maven.compiler.target for Java 1.8. During development I unintentionally added
a Java 11 method in my code `isBlank()` for String objects in this case. Even
though the code should only support Java 8, the maven project compiled without
error. Only when I attempted to run the program on a system that only has Java
8 installed was the problem identified.
