我有一個將數據轉換為 JSON 格式的 java 程序。我能夠成功地將程序構建到 jar 文件中，并在獨立程序中成功使用 jar 的功能。我為調用此 jar 的 Logstash 創建了一個 jruby 插件。運行 Logstash 時：gem build logstash-filter-example.gemspec &&../../logstash-5.6.7.freshinstall/bin/logstash-plugin install logstash-filter-example-0.1.1.gem &&../../logstash-5.6.7.freshinstall/bin/logstash -e 'input { stdin{} } filter { example {} } output {stdout { codec => rubydebug }}'我收到以下錯誤：/dataservice/DataServiceClient.java:156:in `parseQueryRowEntry': java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.node.JsonNodeFactory.numberNode(Ljava/math/BigDecimal;)Lcom/fasterxml/jackson/databind/node/NumericNode;    from com/mike/dataservice/DataServiceClient.java:93:in `toJsonObject'    from com/mike/dataservice/DataServiceClient.java:66:in `getData'    from java/lang/reflect/Method.java:498:in `invoke'    from /Users/michael.dobrin/compilationsFromSource/logstash-5.6.7/logstash-5.6.7.freshinstall/vendor/local_gems/ecdbfdf7/logstash-filter-example-0.1.1/lib/logstash/filters/example.rb:49:in `filter'    from /Users/michael.dobrin/compilationsFromSource/logstash-5.6.7/logstash-5.6.7.freshinstall/logstash-core/lib/logstash/filters/base.rb:145:in `do_filter'    from /Users/michael.dobrin/compilationsFromSource/logstash-5.6.7/logstash-5.6.7.freshinstall/logstash-core/lib/logstash/filters/base.rb:164:in `multi_filter'    from /Users/michael.dobrin/compilationsFromSource/logstash-5.6.7/logstash-5.6.7.freshinstall/logstash-core/lib/logstash/filters/base.rb:164:in `multi_filter'    from org/jruby/RubyArray.java:1613:in `each'由于某種原因，無法識別 numberNode() 方法。但是，使用獨立的 jruby 程序運行我的 jar 時沒有問題，即使使用 Logstash 的本地安裝的 jruby 實例也是如此。此外，該程序成功地使用了我的 jar 文件中的一些方法...... numberNode(Ljava/math/BigDecimal;) 是唯一無法識別的方法。為什么 Logstash 看不到這個？
