Compilations of Java action failed

I built the app through 8.18.18, but I found out that I cannot use publish function. So I decided to move my app to studio pro 9, and converted well. However, it can’t publish my app.   The error code:   Buildfile: C:\Users\ta-gi\OneDrive\Documents\Mendix\App11-main_2\deployment\build_core.xml compile:     [javac] Compiling 199 source files to C:\Users\ta-gi\OneDrive\Documents\Mendix\App11-main_2\deployment\run\bin     [javac] C:\Users\ta-gi\OneDrive\Documents\Mendix\App11-main_2\javasource\communitycommons\ error: method execute in class Core cannot be applied to given types;     [javac]         return Core.execute(c, microflowName, params);     [javac]                    ^     [javac]   required: T     [javac]   found: IContext,String,Map<String,Object>     [javac]   reason: cannot infer type-variable(s) T,R     [javac]     (actual and formal argument lists differ in length)     [javac]   where T,R are type-variables:     [javac]     T extends CoreAction<R> declared in method <T,R>execute(T)     [javac]     R extends Object declared in method <T,R>execute(T)     [javac] C:\Users\ta-gi\OneDrive\Documents\Mendix\App11-main_2\javasource\communitycommons\ warning: [dep-ann] deprecated item is not annotated with @Deprecated     [javac]     public static boolean objectsAreEqual(Object left, Object right) {     [javac]                           ^     [javac] Note: Some input files use or override a deprecated API.     [javac] Note: Recompile with -Xlint:deprecation for details.     [javac] 1 error     [javac] 1 warning BUILD FAILED C:\Users\ta-gi\OneDrive\Documents\Mendix\App11-main_2\deployment\build_core.xml:30: Compile failed; see the compiler error output for details.

You need to upgrade the Community Commons module in your application with the latest from the Marketplace. This will fix the error you are seeing,

I hope this helps.
