Subject DB Migration Tool in Continuum 1.2.3 not working
Date Thu, 15 Jan 2009 17:45:06 GMT
Hello,

Has anyone tried the db migration tool in continuum 1.2.3 using the
instructions in
http://continuum.apache.org/docs/1.2.3/installation/upgrade.html?  I tried
the same procedure in a 1.2.3 database to import to a 1.3.0 (not yet
released) database, but I'm having the following error:

$ java -Xmx512m -jar data-management-cli-1.2.3-app.jar -buildsJdbcUrl
jdbc:derby:/tmp/apache-continuum-1.2.3/data/databases/continuum -mode EXPORT
-directory backups
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/continuum/management/DataManagementCli
$

Then I checked the MANIFEST.MF, only to see that:
Main-Class: org.apache.continuum.management.DataManagementCli

should be (configured in the pom.xml):
Main-Class: org.apache.*maven*.continuum.management.DataManagementCli

I built the codes, but what I'm having next is:
$ java -Xmx512m -jar data-management-cli-1.2.3-app.jar -buildsJdbcUrl
jdbc:derby:/tmp/apache-continuum-1.2.3/data/databases/continuum -mode EXPORT
-directory backups
Exception in thread "main" java.lang.NoClassDefFoundError:
org/codehaus/plexus/PlexusContainer

Looks like it needed plexus-container-default in it, so I added
plexus-container-default-1.0-alpha-9-stable-1, the container that
continuum's maven uses.  Unfortunately, it contains a banned dependency
blocked by the enforcer plugin.  So I incremented until I found something
that built, alpha-16.  I rebuilt the data-management project from the tags,
and tried again.  The next error I encountered is:
$ java -Xmx512m -jar data-management-cli-1.2.3-app.jar -buildsJdbcUrl
jdbc:derby:/tmp/apache-continuum-1.2.3/data/databases/continuum -mode EXPORT
-directory backups

$

A line of code looks for:
properties.load( DataManagementCli.class.getResourceAsStream(
"/META-INF/maven/org.apache.*maven*.continuum/data-management-api/pom.properties"
) );

that should be:
properties.load( DataManagementCli.class.getResourceAsStream(
"/META-INF/maven/org.apache.continuum/data-management-api/pom.properties" )
);

I rebuilt the data-management project again.  But now, I'm having this:
$ java -Xmx512m -jar data-management-cli-1.2.3-app.jar -buildsJdbcUrl
jdbc:derby:/tmp/apache-continuum-1.2.3/data/databases/continuum -mode EXPORT

I figured it's the plexus container again, so I tried upgrading versions,
incrementing until finding alpha-19.  After rebuilding and testing again, I
now have this:
$ java -Xmx512m -jar data-management-cli-1.2.3-app.jar -buildsJdbcUrl
jdbc:derby:/tmp/apache-continuum-1.2.3/data/databases/continuum -mode EXPORT
-directory backups

Exception in thread "main"
org.apache.maven.artifact.resolver.MultipleArtifactsNotFoundException:
Missing:

  Try downloading the file manually from the project website.

  Then, install it using the command:
      mvn install:install-file -DgroupId=org.apache.maven.continuum
-DartifactId=data-management-jdo -Dversion=1.2.3 -Dpackaging=jar
-Dfile=/path/to/file

  Alternatively, if you host your own repository you can deploy the file
there:
      mvn deploy:deploy-file -DgroupId=org.apache.maven.continuum
-DartifactId=data-management-jdo -Dversion=1.2.3 -Dpackaging=jar
-Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

  Path to dependency:
        1) dummy:dummy:pom:1.0
        2) org.apache.maven.continuum:data-management-jdo:jar:1.2.3

----------
1 required artifact is missing.

for artifact:
  dummy:dummy:pom:1.0

from the specified remote repositories:
  central (http://repo1.maven.org/maven2)

Now it's gotten too complicated.  I'll stop for now, maybe you have better
ideas.

Thanks,
Nap
