How to use getEntityProperty() method of PropertyServiceResult class

[Mamikon Papikyan]

Hi atlassian,

I have jira versions 7.x and 8.x and I want to build jira plugin to get two jar files. For jira version 7.x getEntityProperty() method returned:

com.atlassian.fugue.Option<EntityProperty> class type,

for jira version 8.x:

io.atlassian.fugue.Option<EntityProperty> class type,

I check the versions with statement, here my code:

 if (version.equals("7")) {
  com.atlassian.fugue.Option<EntityProperty> jsonValues =
  propertyValues.getEntityProperty();
  entity = jsonValues.getOrNull();
} else {
  io.atlassian.fugue.Option<EntityProperty> jsonValues =
  propertyValues.getEntityProperty();
  entity = jsonValues.getOrNull();
}

When the jira version is 7.x in my pom.xml I get the following error:

package io.atlassian.fugue does not exist

and the case when version is 8.x:

incompatible types: io.atlassian.fugue.Option<com.atlassian.jira.entity.property.EntityProperty> cannot be converted to com.atlassian.fugue.Option<com.atlassian.jira.entity.property.EntityProperty>

How can I solve this problem for in order to my plugin work for both jira versions?

Thanks in advance,

Hello @Mamikon Papikyan ,

This question has been already answered in the below threads, in the developers community and in here:

• Final touches before the Beta - Jira 8.0 EAP 08 … and some GA news
• getEntityProperty() - how to make it work with both JIRA7 and JIRA8? (in here they just point to above thread).

@verenok you mean to build an app that’s compatible with both Jira 7 and Jira 8? There are two approaches:

• build compatibility (adapter) libraries for Jira 7 and Jira 8 (compiling each against the appropriate Jira version) and call the right library based on the Jira version
• use Java introspection to call the methods; since the only difference is in the return type it’s actually easy.

And:

This is what we use to access the property value from the return value of issuePropertyService.getProperty:

  public static <T> T getEntityPropertyOrNull(PropertyResult propertyResult) {
    try {
      Object option = propertyResult.getClass().getMethod("getEntityProperty").invoke(propertyResult);
      return option.getClass().getMethod("getOrNull").invoke(option);
    } catch (InvocationTargetException | NoSuchMethodException | IllegalAccessException var2) {
      throw new IllegalStateException(var2);
    }
  }
