Prerequisities
You will need to have Subversion and Maven installed (in addition to Java and the other DSpace prerequisites.)
Check out DSpace from SVN
To check out DSpace, first determine the version of DSpace you want to install.
A few tips on how the DSpace SVN repository is organized / managed:
- /tags/ - Tagged versions represent*stable, official releases* of DSpace software. If you want to install a supported version of DSpace, find the appropriate tag to checkout.
- /branches/ - Branches are used for development of new minor, bug-fix releases (e.g. 1.4.2, 1.5.1). They should be considered semi-stable, but are not recommended unless you plan to help in development work.
- /trunk/ - Trunk is used for development of the next major version (e.g. 1.4, 1.5, 2.0). It should be considered highly unstable, and is not recommended unless you plan to help in development work.
Once you've chosen your version, check it out as follows (the below example is for DSpace 1.5):
Code Block |
---|
svn co https://scm.dspace.org/svn/repo/dspace/tags/dspace-1_5 /some/where |
Where "/some/where" is a path on the local file system that may be relative or absolute.
This will check out all of the DSpace modules.
Initial Build and Installation
To build DSpace (with PostgreSQL as the database):
Navigate into the directory called "dspace" within your svn checkout.
Code Block |
---|
cd /some/where/dspace/ |
Execute Maven using the following command
Code Block |
---|
mvn package |
Note, one previously had to execute Maven with "assembly:assembly" as an option, this is no longer necessary. Other options for executing maven include designating the database to be used, this can be executed wih the following additional option.
Code Block |
---|
mvn -Ddb.name=[postgres|oracle] package |
This might take a while as required JARs etc are downloaded.
Now you should have a DSpace build in
Code Block |
---|
dspace/target/dspace-1.5-SNAPSHOT.dir |
. Set up a PostgreSQL database as usual. Edit dspace/target/dspace-1.5-SNAPSHOT.dir/config/dspace.cfg
as required. Run:
Code Block |
---|
ant fresh_install |
You may see errors like this, but these don't matter:
Code Block |
---|
[java] log4j:ERROR Could not read configuration file [file:config/log4j-console.properties]. [java] java.io.FileNotFoundException: file:config/log4j-console.properties (No such file or directory) [java] at java.io.FileInputStream.open(Native Method) [java] at java.io.FileInputStream.<init>(FileInputStream.java:106) .... |
as long as you see BUILD SUCCESSFUL you should be OK.
In your DSpace install directory (by default /dspace
), you should see a webapps
dir. Copy these to your Tomcat's webapps
dir.
Now http://localhost:8080/jspui/ should be the 'classic' DSpace UI. http://localhost:8080/xmlui/ should be the XML UI.
Development
Editing the source is now possible using any tools you like.
Using Eclipse is actually very easy if you're on 3.3 and have Subclipse installed. Just create a Java project, specify 'create project from existing source' and point it at /path/to/src
, i.e. the directory with dspace
, dspace-api
etc. in it. Eclipse picks up the source directories and JARs, and even the SVN source control info. You might like to change Eclipse's build directory and remove duplicates and dspace-*.jar
from the JARs in the build path, but as far as source editing with code completion goes you're good.
To deploy your changes (you'll probably want to set up a script to do this!)
Code Block |
---|
$CATALINA_HOME/bin/shutdown.sh cd /path/to/your/src/dspace mvn package cd target/dspace-1.5-SNAPSHOT.dir ant -Dconfig=/dspace/config/dspace.cfg update rm -r $CATALINA_HOME/webapps/dspace-* cp -r /dspace/webapps/* $CATALINA_HOME/webapps/ $CATALINA_HOME/bin/startup.sh |
Warning: the mvn package
will overwrite the dspace.cfg in dspace-1.5-SNAPSHOT.dir/config
.
Keeping up to date with DSpace SVN
In the top level of your checked out DSpace (i.e. the /path/to/your/src
dir) do:
Code Block |
---|
svn up |
You should see messages about what's being updated. If you see 'C' or messages about conflicts by any of the files, you will need to go to the files where there were conflicts and resolve them. See the section entitled "Resolve Conflicts (Merging Others' Changes)" in the SubVersion documentation.
Creating a patch file
NB: Read Code Contribution Guidelines before submitting a patch
To create a patch for all changes, run
Code Block |
---|
svn diff -u > mypatch.txt |
To create a patch for only certain files, run
Code Block |
---|
svn diff -u path/to/files > mypatch.txt |
Applying a patch file
The easiest way to apply a patch is by using the Linux patch
command. For information on what the patch
command does and all of its options, take a look at man patch
from a Linux machine.
TODO: More detail needed
In general, you most likely will want to run a command similar to the following from your [dspace-source] directory (but see the Important Hints below, before running anything!):
Code Block |
---|
patch -p0 < mypatch.txt |
Important Hints:
- It's highly recommended to add the
--dry-run
option initially, in order to test your command first, since not all patches are created equal! - The
--verbose
option is sometimes helpful in understanding what applying the patch is actually doing.
