任何人都可以建议我使用哪个罐来解决以下异常，

Exception in thread "main" java.lang.NoSuchMethodError: org.neo4j.graphdb.factory.GraphDatabaseSetting$BooleanSetting.<init>(Ljava/lang/String;)V

我已经包含了以下jar，

的Neo4j-内核1.9.3.jar。感谢。

确保您拥有匹配的neo4j-shell jar文件。

命令javap -v -classpath neo4j-shell-1.9.3.jar org.neo4j.shell.ShellSettings | grep invoke向我表明ShellSettings只调用了五种方法。一个是Object默认构造函数，但是在ShellSettings的构造函数中，而不是静态类初始化<clinit>。其他人都来自班级org.neo4j.helpers.Settings。 setting在两个不同的重载版本中被调用四次，每次matches和illegalValueMessage。

因此，在neo4j的1.9.3版本中，不会发生对堆栈跟踪中提到的GraphDatabaseSetting$BooleanSetting构造函数的调用。因此，您的ShellSettings类必须来自与1.9.3不二进制兼容的其他版本。使用兼容的版本，你应该没问题。

需要帮助来解决异常java.lang.NoSuchMethodError：org.neo4j.graphdb.factory.GraphDatabaseSetting $ BooleanSetting
