[mkgmap-dev] Eclipse

Mon Oct 27 03:32:50 GMT 2014

Hi Gerd,

The process for Eclipse should be:
1) checkout the source with an svn client, or use the subclipse plugin
2) Install IvyDE plugin (one time) OR manually configure your classpath
after loading the project
3) Add 'Existing Java Project'

If you are running from Eclipse with IvyDE, you should not need to run the
'ant resolve' step. If you have both Subclipse and IvyDE installed, you
should be able to start work on an existing project just by adding the SVN
url.

Regarding the settings, my workspace default was not Java 1.7. This
required setting project specific settings. Eclipse doesn't let you just
set one project specific setting though, hence it makes a copy of all the
other existing defaults. For projects with multiple Eclipse developers,
it's usually a net benefit for everyone to be using the same set of
settings. Half because it avoid compile problems, and half because it keeps
the styles in sync. For example, you don't want some developers saving
files with encoding CP-1251 and others saving UTF-8.

With the current state of Eclipse, it took me several hours before I had a
build with no compile errors. I'm hoping the patch might save someone else
a bit of time with a new Eclipse setup.
