Re: [jbosstools-dev] Fwd: Fwd: [m2e-dev] Questions about the Maven Builder

Hi Alexey, see Igor's reply : ---------- Forwarded message ---------- From: *Igor Fedorenko* <igor(a)ifedorenko.com <mailto:igor@ifedorenko.com>> Date: 2011/7/25 Subject: Re: [m2e-dev] Questions about the Maven Builder To: m2e-dev(a)eclipse.org <mailto:m2e-dev@eclipse.org> In theory, builders order should not matter. Builders produce workspace changes, so if m2e builder changed any workspace resources, this will trigger new build cycle (assuming workspace build is ON, of course), and these changes will be picked up by other builders. Project metadata changes is another story. Although I have not seen this is documented anywhere, I believe general assumption is that project configuration is (relatively) static and does not change as a result of project build. So if maven builder changes or updates project configuration (things like application.xml and OSGi bundle manifest), it sort of falls into a gray territory, in theory everything is supposed to work, but in practice some tools may get confused and may need extra help to "notice" new project metadata. -- Regards, Igor m2e configurators (JDT, WTP, JSF, CDI ...) are all called by the maven builder, hence the phrase "if m2e builder changed any workspace resources ...". As a matter of fact, resources are being created/changed by these configurators, generating new build cycles. HIH.

Eventually we found the reason of not-working code completion. It's not related to maven stuff at all (he didn't install JSF tools: https://issues.jboss.org/browse/JBIDE-9397 ). But anyway, could it be a problem if the maven builder declared last? For instance: 1. Java builder build the project. 2. CDI builder builds the project using Java model (cdi builder should be declared after Java builder and we create a problem marker if it's not so). 3. KB builder builds the project using Java model (so we check the build order again). 4. WST validation builder validate the project. We extend this validation and check if CDI, KB, Seam builders declared before the WST builder. So, what about Maven? Does it do anything that could influence CDI, JSF, Seam and don't trigger a new cycle of building? Should we care if maven declared after CDI/KB/WST? I tested Jose's project and everything seems to work, but I could miss something. Thanks for you insights.
