Can we use stream api when builgind add-on for JIRA?

[safaksahin]

Hi,

I am currently using atlassian-plugin-sdk-6.12.14 for developing add-ons.

I tried to use Stream API in my code and when i tried the re-package maven gives me this error:

Foo.java[2,77] method references are not supported in -source 1.5

Bold area is error line :

List<Project> allProjectList = ComponentAccessor.getProjectManager().getProjectObjects();

       Map<String, Object context = allProjectList.stream().collect(Collectors.toMap(Project::getName, Function.identity()));

Put the following lines in pom.xml

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
    </configuration>
</plugin>

 If you already have them but with different versions of source and target change the versions to 1.8
