2011-12-16Enforce the use of Java5 API:s only (with a few exceptions)Robin Rosenberg1-0/+6
This only works with Eclipse 3.6 and newer and requires installation of new package. Documentation is not very good, but there is a blog about it here: http://eclipseandjazz.blogspot.com/2011/10/of-invalid-references-to-system.html API checking is especially useful on OS X where Java5 is not readily available.

2010-08-28Revert "Hide Maven target directories from Eclipse"Robin Rosenberg1-11/+0
This reverts commit db4c516f673e4c274e55adc27a95891c52a5aba8 since it breaks compatibility with Eclipse 3.5 which can no longer import the projects Bug: 323390 Change-Id: I3cc91364a6747cfcb4c611a9be5258f81562f726

2010-01-10Partial revert "Switch build to Apache Felix maven-bundle-plugin"Robin Rosenberg1-0/+28
This restores the ability to build using just Eclipse without strange procedures, extra plugins and it is again possible to work on both JGit and EGit in the same Eclipse workspace with ease.

2009-12-28Switch build to Apache Felix maven-bundle-pluginShawn O. Pearce1-28/+0
Tycho isn't production ready for projects like JGit to be using as their primary build driver. Some problems we ran into with Tycho 0.6.0 that are preventing us from using it are: * Tycho can't run offline The P2 artifact resolver cannot perform its work offline. If the build system has no network connection, it cannot compile a project through Tycho. This is insane for a distributed version control system where developers are used to being offline during development and local testing. * Magic state in ~/.m2/repository/.meta/p2-metadata.properties Earlier iterations of this patch tried to use a hybrid build, where Tycho was only used for the Eclipse specific feature and P2 update site, and maven-bundle-plugin was used for the other code. This build seemed to work, but only due to magic Tycho specific state held in my local home directory. This means builds are not consistently repeatable across systems, and lead me to believe I had a valid build, when in fact I did not. * Manifest-first build produces incomplete POMs The POM created by the manifest-first build format does not contain the dependency chain, leading a downstream consumer to not import the runtime dependencies necessary to execute the bundle it has imported. In JGit's case, this means JSch isn't included in our dependency chain. * Manifest-first build produces POMs unreadable by Maven 2.x JGit has existing application consumers who are relying on Maven 2.x builds. Forcing them to step up to an alpha release of Maven 3 is simply unacceptable. * OSGi bundle export data management is tedious Editing each of our pom.xml files to mark a new release is difficult enough as it is. Editing every MANIFEST.MF file to list our exported packages and their current version number is something a machine should do, not a human. Yet the Tycho OSGi way unfortunately demands that a human do this work. * OSGi bundle import data management is tedious There isn't a way in the MANIFEST.MF file format to reuse the same version tags across all of our imports, but we want to have a consistent view of our dependencies when we compile JGit. After wasting more than 2 full days trying to get Tycho to work, I've decided its a lost cause right now. We need to be chasing down bugs and critical features, not trying to bridge the gap between the stable Maven repository format and the undocumented P2 format used only by Eclipse. So, switch the build to use Apache Felix's maven-bundle-plugin. This is the same plugin Jetty uses to produce their OSGi bundle manifests, and is the same plugin used by the Apache Felix project, which is an open-source OSGi runtime. It has a reasonable number of folks using it for production builds, and is running on top of the stable Maven 2.x code base. With this switch we get automatically generated MANIFEST.MF files based on reasonably sane default rules, which reduces the amount of things we have to maintain by hand. When necessary, we can add a few lines of XML to our POMs to tweak the output. Our build artifacts are still fully compatible with Maven 2.x, so any downstream consumers are still able to use our build products, without stepping up to Maven 3.x. Our artifacts are also valid as OSGi bundles, provided they are organized on disk into a repository that the runtime can read. With maven-bundle-plugin the build runs offline, as much as Maven 2.x is able to run offline anyway, so we're able to return to a distributed development environment again. By generating MANIFEST.MF at the top level of each project (and therefore outside of the target directory), we're still compatible with Eclipse's PDE tooling. Our projects can be imported as standard Maven projects using the m2eclipse plugin, but the PDE will think they are vaild plugins and make them available for plugin builds, or while debugging another workbench. This change also completely removes Tycho from the build. Unfortunately, Tycho 0.6.0's pom-first dependency resolver is broken when resolving a pom-first plugin bundle through a manifest-first feature package, so bundle org.eclipse.jgit can't be resolved, even though it might actually exist in the local Maven repository. Rather than fight with Tycho any further, I'm just declaring it plugina-non-grata and ripping it out of the build. Since there are very few tools to build a P2 format repository, and no documentation on how to create one without running the Eclipse UI manually by poking buttons, I'm declaring that we are not going to produce a P2 update site from our automated builds.

2009-11-03Create JUnit test utilities for JGit derived sourcesShawn O. Pearce1-0/+28
The LocalDiskRepositoryTestCase class is derived from the current RepositoryTestCase code and is meant for application (or our own) tests to subclass and access temporary repositories on the local client disk.
