Issue Summary

Bamboo Specs export with multiline Dockerfile produces invalid Java

This is reproducible on Data Center: yes

Steps to Reproduce

1. Add a Docker task of type Build to your build plan
2. Add a multiline Dockerfile such as:

   FROM node:12-alpine
   RUN apk add --no-cache python2 g++ make
   

3. Plan Configuration >> Actions >> Export as Java Specs

Expected Results

Java generated is valid

Actual Results

The Java generated is invalid, it contains a multiline string:

 new DockerBuildImageTask()
         .imageName("asdsadas")
         .useCache(true)
         .dockerfile("FROM node:12.18.1
RUN apk add --no-cache python2 g++ make"),

This causes compilation errors when publishing:

[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] /Users/user/stored-spec/bamboo-specs/src/main/java/tutorial/PlanSpec.java:[47,49] unclosed string literal

Workaround

Manually change the Java Spec after exporting it to use newline characters E.g.

     .dockerfile("FROM node:12.18.1\nRUN apk add --no-cache python2 g++ make"),
