Question

这是我的pom.xml。当我mvn package并尝试执行jar

时

$ java -jar fft-java-1.0.0.jar

我收到如下错误消息..

java.lang.NoClassDefFoundError: org/jtransforms/fft/DoubleFFT_2D

的pom.xml

                            <classpathPrefix>lib/</classpathPrefix>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

但我实际上能够在包org.jtransforms.fft中看到类DoubleFFT_2D 我该如何解决这个问题？

Answer 1

检查您的清单是否有导入。或者首先在项目上尝试mvm clean install，然后尝试使用mvm clean package。

使用maven打包时出现NoClassDefinitionFoundError
