Maven cannot find Lombok's ExtensionMethod during compilation -

i'm using eclipse , have mulitmodule maven project in use lombok(1.16.4) java=jdk1.7.0_71.

in eclipse code compiles , junit testes pass. in maven (v. 3.2.3 , 3.3.3) code not compile.

[error] compilation error :  [info] ------------------------------------------------------------- [error] determinemarketdirection.java:[86,42] cannot find symbol   symbol:   method sumvaluesdouble(java.lang.string)   location: variable listtoworkon of type java.util.list<t> [info] 1 error 

this sumvaluesdouble lombok's extension method type list<> defined in module a. error above occures in module c depends on module a.

this part of extensionlist.java:

public static <t> double sumvaluesdouble(list<t> list, final string methodname) {         return sumvaluesof(list, methodname, double.class);     }      private static <t, n extends number> n sumvaluesof(list<t> list, final string methodname, class<n> type) {          function<t, n> transform = new function<t, n>() {             @suppresswarnings("unchecked")             @override             @sneakythrows             public n apply(t from) {                 method method = from.getclass().getmethod(methodname);                 return (n) method.invoke(from);             }         };          list<n> projectedlist = lists.transform(list, transform);         return sumall(projectedlist);     } 

it's strange because have tests in module a extension method , compile ok , pass.

part of test module a:

@extensionmethod({ extensionlist.class }) public class extensionlistsumalltest {     @test     public void testdouble() {         list<valuedouble> listdouble = new arraylist<>();         listdouble.add(new valuedouble(1, 1d));         listdouble.add(new valuedouble(2, 2d));         listdouble.add(new valuedouble(3, 3d));         double actual = listdouble.sumvaluesdouble("getvalue");         final double expected = 6d;         assertequals(expected, actual);     }      @allargsconstructor     @getter     public class valuedouble {         private final integer id;         private final double value;     } } 

what can make maven "see" method?

btw: use lot of extension methods in module c , maven has problem one. in project/eclipse use lombok long time , didn't had such problem before.

update:

i played little bit more , found out, when add 'dummy' code before execution of extension method maven compile code wihtout problems.

so, not compile

@slf4j @extensionmethod({ extensionlist.class }) public class smacalculator {     static <c extends candle> double calculatesma(list<c> candles, int sma) {         list<c> listtoworkon = preparelistforsmacalculation(candles, sma);          double sum = listtoworkon.sumvaluesof("getcloseprice");          double smavalue = sum / sma;         return smavalue;     } ...other methods... } 

but compiles maven, , dupa object not referes listtoworkon object:

static <c extends candle> double calculatesma(list<c> candles, int sma) {     list<c> listtoworkon = preparelistforsmacalculation(candles, sma);      list<c> dupa = new arraylist<c>();     dupa.add(listtoworkon.first());     dupa.sumvaluesof("getcloseprice");      double sum = listtoworkon.sumvaluesof("getcloseprice");      double smavalue = sum / sma;     return smavalue; } 

i had same problem, after switching 1.16.2 , seems work.
