Question

我在Eclipse中执行java代码时遇到错误（我没有使用Maven）

a = 3
attr(a, 'time_defined') = Sys.time()
b = 4
attr(b, 'time_defined') = Sys.time()

save(a, b, file = 'my_data.RData')

# ... later on ...

load('my_data.RData')

if(difftime(attr(a, 'time_defined'), Sys.time(), units = 'days') > 10) # do the following if more than 10 days old

我正在使用罐子：

Exception in thread "main" java.lang.NoSuchMethodError: org.codehaus.jackson.JsonFactory.enable(Lorg/codehaus/jackson/JsonParser$Feature;)Lorg/codehaus/jackson/JsonFactory;
    at org.apache.avro.Schema.<clinit>(Schema.java:88)

    at com.rishav.avro.AvroExampleWithoutCodeGeneration.main(AvroExampleWithoutCodeGeneration.java:94)

第36行 - ＆gt; Schema schema = new Schema.Parser（）。parse（new File（“StudentActivity.avsc”））;

Answer 1

你可以改为：

Schema schema = new Schema.Parser().parse.newFile("resources/StudentActivity.avsc");

java.lang.NoSuchMethodError：org.codehaus.jackson.JsonFactory.enable（Lorg / codehaus / jackson / JsonParser $ Feature;
