Subject [jira] [Commented] (DERBY-6645) Switch to Maven for building Apache Derby
Date Thu, 09 May 2019 21:01:00 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6645?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16836696#comment-16836696
] 

Davide Grandi commented on DERBY-6645:
--------------------------------------

Upon suggestion of [~rhillegas] I've attached a pdf map of current (revision 1859039) trunk's
build.xml (build.xml.dot.pdf).

The map has been generated by a short XSLT stylesheet that navigate build.xml archive spitting
out a "build.xml.dot" file.
With Graphviz this dot file is transformed in a map connecting Ant targets with their prerequisites
(with an index on the arc).
The arcs are drawn in bold for antcall dependencies and in red for exec ones.

I've attached a zipped script (for windows and linux - build2dot.zip) that run the XSLT stylesheet,
with 2 samples : one for JTOpen and one for Derby.
To run you should :

- set the JAVA_HOME env var
- launch it with
  build2dot.sh build.xml
- then run Graphviz with
  dot -Tpdf -O build.xml.dot
- view the generated build.xml.dot.pdf file with, e.g., "evince"
  evince build.xml.dot.pdf

Best regards,

    Davide Grandi

> For a new user building Derby is very hard. It does not follow established Java project
structures and requires a lot of prior knowledge. Also the documentation is rather short.
Especially running the tests is non-intuitive at the beginning. Thus, I propose that Derby
switches to building using Maven and restructures its components in a cleaner way. Testing
should be revised to produce reproducible results. This would make development and testing
much easier and more user-friendly.
