DefaultM.netaryConversionsSingletonSpi 无法实例化

Question

I am using Java money API in Eclipse to get convert USD to EUR but I am getting following error

Provider org.javamoney.m.neta.internal.convert.DefaultM.netaryConversionsSingletonSpi could not be instantiated

Below is the code from my POM

<dependency>
  <groupId>org.javamoney</groupId>
  <artifactId>moneta</artifactId>
  <version>1.2.1</version>
  <type>pom</type>
</dependency>

Below is the full error

[Handler processing failed; nested exception is java.util.ServiceConfigurationError: javax.money.spi.MonetaryConversionsSingletonSpi: Provider org.javamoney.moneta.internal.convert.DefaultMonetaryConversionsSingletonSpi could not be instantiated] with root cause
java.lang.NoSuchMethodError: org.javamoney.moneta.spi.MonetaryConfig.getString(Ljava/lang/String;)Ljava/util/Optional;

Answer 1

I see that you are trying to use method (or some library that you youse)

Optional org.javamoney.moneta.spi.MonetaryConfig.getString(String)

but there is no such method. There is only

Map<String,String> org.javamoney.moneta.spi.MonetaryConfig.getString()

V1,0 , V1.4 and latest

Please check your code against this method, if not help, then try to use newest version.
