Flexmojos compatibility with Flex SDK to 4.5

I was working on a project with flexmojos 3.9 and Flex 4.0. I decided to upgrafe my version of the flex SDK to 4.5 but I have the followin problems:

1- Maven Message: [FATAL ERROR] org.sonatype.flexmoj开发者_Python百科os.optimizer.OptimizerMojo#execute() caused a linkage error (java.lang.NoSuchMethodError) and may be out-of-date. Check the realms

2- Stack trace: java.lang.NoSuchMethodError:flex2.compiler.common.Configuration.setKeepDebugOpcodes(Z)V

Regards,

FlexMojos 3.9 is extremely outdated and you should look into 4.0-RC1 from https://repository.sonatype.org/content/repositories/maven-sites/flexmojos/
