Running your own Repository Reports


This document gives a brief outline of how to run the "repo reports" locally, against a repository on your local file system.

There are some tests, that look at jars specifically, that require the jars to be on local file system and essentially use plain 'ol Java file IO and regex-type checks on the contents. <p>Another class of tests, read the content.jar/xml meta-data and reports on the data or relationships in that meta data. <p> <p>Yet another, small class of tests, verify the jars are signed. These tests are not really "Java" or "workspace" related, but instead, use shell scripts to invoke "jarsigner -verify" repeatedly on a directory of jars. These shell scripts are not very efficient, but ... do get the basic signature verification checks done in the most neutral, flexible way possible. They make sure jars are signed and that pack.gz files can be unpacked, and then the signature of the resulting jar verified. You can change the VM level used since there are known issues with each level of VM; some jars can not be unpacked with java 5, say, or those with nested jars can not be unpacked with Java 7. Which VM level to use depends on your goals and end-user and adopter needs. (We use Java 6 during the report generation on for Simultaneous Release.)

Running the repo tests

These instructions are focus for "running from your workspace", but could also easily be done "from the command line" if you know how to run Eclipse Applications from the command line.

The Basics

The Eclipse Application is named 'org.eclipse.simrel.tests.repoReport'. It takes two "system properties"; one to specify where you want the output to go, and another to specify where the repo is on the file system. For example:

  • -DreportOutputDir=/home/shared/eclipse/repoReport
  • -DreportRepoDir=/home/www/html/downloads/eclipse/updates/4.2-I-builds/I20120531-1500/

The Details

The source project is named 'org.eclipse.simrel.tests' and is currently in Git in repository named 'simrel/org.eclipse.simrel.tests.git'. See org.eclipse.simrel.tests.git (browse, stats, fork on OrionHub) .

Once you load that project into your workspace, it will include one "launch configuration" that can be used as a starting example, edited and used to launch the application from your workspace.<p> <p>On a large repository, it take 5 or 10 minutes to complete, and then you just to look at the results (usually) with a web browser starting with the 'index.html' at the location you specified in 'reportOutputDir' property.<p>

Signing verification

There are two scripts in the 'org.eclipse.juno.tests' that work together to check signatures: and Written for Linux, but could be re-written for Windows, I'd guess. I normally put these on my path, such as in my ~/bin directory. The run time, I navigate to the "top" of the repository, and execute ./ which uses the current directory (if none specified) and iterates through all the files looking for "*.jar" and '*pack.gz' files and eventually calls '' on a specific file. You will need to edit and define the Java directory on your local system where "jarsigner" can be found. Once ran, the scripts create report files in ~/verifyoutputdir (in your home folder, erasing what ever was there before) and you can check those report files for "errors" or "unsigned" items.

Getting help or making contributions

You can ask questions on cross-project list if the tests do not work as expected. Or, even better, you can make improvements/fixes directly on this wiki, if the instructions can be better. Feel free to supply patches on the cross-project component in bugzilla.
