ANT is using Java 1.6 JRE by default which is not suitable anymore for Java 11 features. Defining a source and target version fixed it for me on using maven, which behaves the same way in that case.

<property name="ant.build.javac.source" value="11"/>
<property name="ant.build.javac.target" value="11"/>
