Wiremock Placeholder isn't recognized - wiremock

Question

I tried with the following json but the wiremock doesn't recognize my change. I read the documentation of wiremock and I saw that they said: JSON equality matching is based on JsonUnit and therefore supports placeholders. I also tried with both JDK 8 and JDK 13 but both are not working
Below is the detail
"method" : "POST",
"bodyPatterns" : [{
"equalToJson" : {
"recipient": {
"address": {
"city": "Bellevue",
"postalCode": "52031",
"countryCode": "US"
}
},
"sender": {
"address": {
"city": "",
"postalCode": "",
"countryCode": "HK"
}
},
"shipDate": "${json-unit.any-string}",
"accountNumber": {
"key": ""
}
},
Result when running selenium test with mock (I executed mock via java -jar tmp/wiremock.jar --global-response-templating --root-dir ./mock --port 1337 ):

"recipient" : { | "recipient" : {
"address" : { | "address" : {
"city" : "Bellevue", | "city" : "Bellevue",
"postalCode" : "52031", | "postalCode" : "52031",
"countryCode" : "US" | "countryCode" : "US"
} | }
}, | },
"sender" : { | "sender" : {
"address" : { | "address" : {
"city" : "", | "city" : "",
"postalCode" : "", | "postalCode" : "",
"countryCode" : "HK" | "countryCode" : "HK"
} | }
}, | },
"shipDate" : "${json-unit.any-string}", | "shipDate" : "May-26-2020",
"accountNumber" : { | "accountNumber" : {
"key" : "" | "key" : ""
} | }
} | }

Can anybody make some suggestions here. Thank you for reading my question

Answer 1

The usage of "${json-unit.any-string}" is right. But placeholder works when the right dependency is used.
Using dependency com.github.tomakehurst:wiremock-jre8 worked for me.
Refer https://wiremock.org/docs/request-matching/ for more info. This would mention the following note
Placeholders are only available in the jre8 WireMock JARs, as the JsonUnit library requires at least Java 8.

Answer 2

you have to enable the placeholder as below and you should make sure you are using the jre-standalone jar. you seem to be using the normal standalone jar
"enablePlaceholders" : true
