git - mutliple project branches with maven -


i working pretty large project , want work on multiple branches of it. 1 of @ present older version of other, , poms same. i'd avoid changing version numbers in pom files since may require rewriting of them, , later make merging more tricky. simplest way jars produced mvn clean install don't overwrite ones in different branch placed in .mvn/repository ?

note: working git , found git-new-workdir script (available in git source repo) useful here in @ least allows jars produced in source tree hierarchy co-exist in different subdirectories.

so of course 1 simple answer have repository each branch. eg

  • .m2/repository
  • .m2/branch1/repository

then 1 can run mvn install -o -dmaven.repo.local=~/.m2/branch1/repository

of course nice if 1 clone links old repository not have download files. can done 

$ cd .m2 $ mkdir branch1 $ find repository -type d -exec mkdir branch1/{} \; $ find repository -type f -exec ln {} \;  branch1/{} \;

but repository.xml seems full of absolute directory url pointers. (why can't use relative urls?) anyway, not seem download of them, or @ least compilation lot faster expected.

the solution discovered in comment non-intrusive one.

the next best thing versions-maven-plugin, automates changing poms in different branches. sadly, i'm unaware of component out there allows automate process of discouraging git merging these changes along others.

sql - text truncated using perl DBI insert -

the problem dbi 's insert leaves long string truncated when inserting ms sql server. here codes: my $insert = $dbh->prepare("insert my_table (field_1, field_2) values (?, ?)"); $insert->execute($value_1, $value_2); where field_2 has data type of varchar(100) , $value_2 text string of 90 characters spaces no other special characters. after statement executed, no error raised, checked database , apparently actual inserted $value_2 truncated @ 80th character, in middle of regular english word (i.e. not special character). i've tried alter data type of field_2 varchar(150) , text . i've used $dbh->quote($value_2) in place of $value_2 . didn't help. why happening? should do? thx!! if using freetds bug identified in freetds mailing list. see freetds silently truncating text/varchar/etc fields 80 characters , http://lists.ibiblio.org/pipermail/freetds/2011q2/026943.html , http://lists.ibiblio.org/pipermail/freetds/2011q2/026...
