I tried to run my app locally but an error saying ‘Compilation of Java actions failed’ appears. I already tried cleaning deployment directory but it didn’t help. This are the error details: Buildfile: C:\Users\daniel.fbastos\Mendix\InnopointsMockService-main\deployment\build_core.xml compile: [javac] Compiling 239 source files to C:\Users\daniel.fbastos\Mendix\InnopointsMockService-main\deployment\run\bin [javac] C:\Users\daniel.fbastos\Mendix\InnopointsMockService-main\javasource\module\proxies\User.java:95: error: load(IContext,String) in User cannot hide load(IContext,String) in Account [javac] public static java.util.List<module.proxies.User> load(com.mendix.systemwideinterfaces.core.IContext context, java.lang.String xpathConstraint) throws com.mendix.core.CoreException [javac] ^ [javac] return type List<User> is not compatible with List<Account> [javac] Note: Some input files use or override a deprecated API.

It looks like you created or changed a java action to return a list of Account (in Studio Pro) but your java source code returns a list of User.
An Account is (by default) a User by inheritance (specialization), but a User (generalization) is not always an Account.
Deploy your project for Eclipse and change your Java source code accordingly.
