Job Barometer

I want my job to give me:

• Autonomy to decide what I work on and how I go about it ✅
• Small feedback cycles and ability to experiment (e.g. being able to release frequently) ❌
• Novelty (not doing the same thing over and over) ✅
• Purpose (I can agree with the team's goals) ✅
• People to collaborate with, learn from, and teach ✅

I want to avoid:

Problem

I want to build a container inside my circleci build and mount files from the outer build environment.

Running this docker command works outside of circleci, but not on circleci (when using the docker exectutor with setup_remote_docker).

circleci@07b4d1bb33c0:/tmp/workspace$ docker run -p 7001:7001 -p 9002:9002 -v $(pwd):/u01/oracle/properties store/oracle/weblogic:12.2.1.3
Domain Home is:  /u01/oracle/user_projects/domains/base_domain
awk: warning: command line argument `/u01/oracle/properties/domain.properties' is a directory: skipped
The domain username is blank. The Admin username must be set in the properties file.

Adopt a modern build tool

Context

• The existing build scripts used ant
• We had multiple build artefacts, ant scripts and property files
• A lot of configuration was targeted at a specific environment and OS (windows)
• Dependencies were bundled with the project

Problem

• The build scripts were difficult to understand
• Ant is not a technology we use for other projects so developers are unfamiliar with it
