IntelliJ IDEA 13 uses Java 1.5 despite setting to 1.7
compilation, intellij-idea, java
Solution
If nothing of this helps (my case), you can set it in your pom.xml, like this:
<properties>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
</properties>

Problem
Despite specifying JDK 1.7 in all project settings (including in `File -> Project Structure -> Project :: Project SDK`), the following error is produced by `IntelliJ 13` when trying to compile some simple Java 7 code which does use the diamond operator: ``` java: diamond operator is not supported in -source 1.5 (use -source 7 or higher to enable diamond operator) ``` Is there any other place in the configuration where the expected `-source 7` option should be enabled?
