Dan Rollo created MNGSITE-147:
---------------------------------
Summary: guide-m2-development should state recommended version of
Ant (eg: 1.7.1 fails, and is still the default in some LTS distros).
Key: MNGSITE-147
URL: https://jira.codehaus.org/browse/MNGSITE-147
Project: Maven Project Web Site
Issue Type: Bug
Reporter: Dan Rollo
The "guide-m2-development" ("Guide to Developing Maven",
"http://maven.apache.org/guides/development/guide-m2-development.html";) section:
"Don't forget tests!" does not mention a recommended version of Ant to use. I
found the hard way that Ant version:
Apache Ant version 1.7.1 compiled on September 8 2010
will fail with an error like:
BUILD FAILED
/home/dan/javadev/maven/maven-3/trunk/build.xml:228: Syntax error in property:
${
There is a bug in Ant that is apparently fixed in Ant 1.8+.
(see: http://comments.gmane.org/gmane.comp.jakarta.turbine.maven.devel/98115 )
Ant 1.7.1 was the default in my linux environment (Ubuntu 10.04 LTS), and I
expect others might hit this same bug and not be so lucky in searching for a
cause/solution.
I will attach a doc patch that recommends Ant 1.8+.
(I tried to find a way to verify the Ant version in the build.xml, but couldn't
find a way that was not coupled to known versions).
Also (and sorry to overload this report with another issue), I think the
current guide-m2-development.apt in subversion includes another error:
The 'ant all' command was moved up to the same line that sets the M2_HOME env
var. Also, that M2_HOME env var line is missing the export command. The patch
fixes these as well.
