Neo4j自定义UserFunction插件无法加载问题求助

我编写了一个自定义UserFunction，希望导入Neo4j中。将jar包放置在$NEO4j_HOME/plugins目录并重启数据库后，Neo4j和Java均无报错，但该函数始终无法被找到。执行SHOW FUNCTIONS YIELD *语句后，未找到该自定义函数。

自定义函数代码 #

@UserFunction
@Description("procedure.getPixelDist(012345678, 012345678, 10) - calculate the distance between the two pixels.")
public boolean getPixelDist(@Name("p1") String pixelOne, @Name("p2") String pixelSecond,
                               @Name("threshold") Integer threshold) throws Exception;

我已尝试网上能找到的所有方法，但问题仍未解决，恳请各位提供帮助。
