Minecraft (ebuild to build deps from source!)

Are you sure that works? I found the JSON gets replaced automatically on each start. You can set it to read only though. The problem with this approach is that it only works after you've started that version of the game once. I think there may have been some other issue too, can't remember.

It looks like the game only overwrites things it already knows about; if you copy 1.6.2/ to a different-named directory and edit the "id:" line in the JSON it'll leave it alone. The 1.6 mods I've installed use the same procedure.

Thanks for reporting that. With the switch to git, I'm now committing using repoman and I'm signing the manifests but maybe I tripped up somewhere. I'm more than familiar with git and repoman is supposed to prevent things like this so I'm not sure what happened but I'll double-check before pushing next time.

I was going to announce the new ebuild but just after pushing it, I realised the new Python script didn't work with the older versions of the game. I've fixed that now but I'm waiting for a bump of dev-java/asm in the main tree before I push it up. As things stand, the new ebuild should work with the 1.6.2.

Looks like it was a repoman bug. The problem went away after updating Portage.

It looks like the dev-java/asm bump may take a little longer so I've pushed out an update to the Python script anyway. For now, it just uses the upstream bundled version of asm. I've tried Minecraft 1.2.5 and even 1.0.0 and they both seem to work. Not that anyone cares about those old versions!

When updating, it'll look like a downgrade because we're now following the upstream launcher version numbers. Be sure to read the instructions after emerging, which will explain how to activate the use of Gentoo's packages. This no longer happens by default.

Someone else reported this problem to me but I didn't have a chance to look at it yet. They were using Paludis so I thought that maybe that was the reason. It looks like it's actually FEATURES="userpriv". I don't try to modify the original jar but the stupid zip command creates a temporary file in /var/tmp/portage/games-action/minecraft-1.2.1/distdir, which the portage user doesn't have write access to. I'll fix this later today.

Done it already! zip has a --temp-path option so it was a quicker fix than I thought.

Thanks, that log was very helpful. It's almost certainly because you need dev-java/java-config-2.2.0. Can you update that and try again? I'll update the ebuild accordingly if that works.

It's not obvious but looking at java-vm-2.eclass, it seems the only thing blocking you from using later versions is the fact that you have eselect-java installed. Uninstall that and you should be able to update.

Edit: Sorry, I was talking out my ass before. The above is still true but eselect-java is still in the tree. I'll talk to #gentoo-java anyway.

vootey · Post by **vootey** » Wed Sep 04, 2013 11:06 am

I just want to say that it works for me.
On my system the java-overlay is masked except the packages used by minecraft.
In particular that means that java-config-2.2.0::java is masked while java-config-2.2.0::gentoo is not (therefore the official version is installed). Also there are more situations like this (like eselect-java).
Maybe these two ebuilds are different (didn't check) which could explain the behaviour on your side. (?)

Just a thought.

Thank you for this hint, but afaik java overlay packages are masked by default and on my system only those packages are unmasked which are really needed as dependency (e.g. for minecraft or dev-util/eclipse-sdk-bin). Anyway, I tried to emerge ~sys-apps/baselayout-java-0.1.0::gentoo ~java-config-2.2.0::gentoo as well as ~sys-apps/baselayout-java-0.1.0::java ~java-config-2.2.0::java, both with the same result:

Okay, I think I get it now. sys-apps/baselayout-java-0.1.0 is not a blocker, in fact, it's the other way round. You can't install that alongside any version of java-config less than 2.2. And therein lies the problem. You can't resolve it without completely uninstalling java-config first. I can't remember if I had to do the same. Again, I'll raise it on #gentoo-java.

For what it's worth, I'll make Minecraft work with older java-config versions anyway but I'd like to see your issue fixed.

Post by **Chewi** » Wed Sep 04, 2013 9:09 pm

TomWij, a developer in #gentoo-java has pointed out that [blocks b ] means it can be automatically resolved. An upper-case B means it cannot. In other words, you just need to remove your -p option and go for it!

I could only find dev-ruby/bouncy-castle-java, which I presume is not the right package.

Gee, you're hitting every damn bump in the road here. I think this shows that maybe I need to be a little stricter about the versions. Just because two versions share the same slot, it doesn't mean the older version is forwards compatible. The package you're after is dev-java/bcprov. What version do you have now?

My current version is dev-java/bcprov-1.38-r2

When I tried with 1.40 and 1.45 the problem persists. The higher versions are installed to slots, I guess minecraft does not use them. First I tried a deepclean but this kept 1.38 and unmerged the others:

Code: Select all

emerge -avc

...

>>> These are the packages that would be unmerged:

 dev-java/bcprov
    selected: 1.40-r1 
   protected: none 
     omitted: 1.38-r2 1.38-r3 

 dev-java/bcprov
    selected: 1.45-r1 
   protected: none 
     omitted: 1.38-r2 1.38-r3

I had to unmerge 1.38 explicitly and install 1.40 and 1.45 respectively to test minecraft with those versions. The good news is that both worked!

But here is the next "bump":

Code: Select all

emerge -a --update --newuse --deep --with-bdeps=y @world
These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  NS    ] dev-java/bcprov-1.38-r3 [1.40-r1] USE="-doc -source" 
[ebuild  NS    ] dev-java/bcprov-1.38-r2 [1.40-r1] USE="-doc -source"

This is caused by some packages that explicitly want dev-java/bcprov-1.38.

Code: Select all

 equery depends dev-java/bcprov
 * These packages depend on dev-java/bcprov:
dev-java/bcmail-1.38-r2 (~dev-java/bcprov-1.38:0)
dev-java/pdfbox-0.7.3-r3 (dev-java/bcprov:1.38)
games-action/minecraft-1.2.1-r1 (dev-java/bcprov:0)

dev-java/bcmail is a dependency of dev-java/pdfbox which itself is a dependency of app-text/texlive-2012 with USE=pdfannotextractor:

Code: Select all

equery depends dev-java/pdfbox
 * These packages depend on dev-java/pdfbox:
dev-tex/pdfannotextractor-0.1l (dev-java/pdfbox)

equery depends dev-tex/pdfannotextractor
 * These packages depend on dev-tex/pdfannotextractor:
app-text/texlive-2012 (pdfannotextractor ? dev-tex/pdfannotextractor)

Conclusion:
games-action/minecraft should depend on >dev-java/bcprov-1.38 and use the right slot.

The versioning and slotting of these packages is a little complicated. Your problem essentially boils down to mixing stable and unstable. However, after a long and confusing conversion with TomWij, we concluded that bcmail-1.38-r2 should depend on bcmail with slot 1.38 and not slot 0. He is now evaluating this change carefully because it will affect stable.

In the meantime, I have bumped Minecraft to -r3 so that it now depends on >=bcmail-1.47:0 and >=commons-io-2.4:1. Why 1.47? That's what upstream uses. With a current Portage tree, slot 0 will actually give you 1.49, which seems to work. I have also gone through the other dependencies and reasoned that these do not need further adjustment at this time.

I picked up the minecraft-server ebuild again tonight. It now uses many of these same dependencies. 1.6.2 runs in the foreground but I'm having some trouble running it under tmux and I haven't had time to fully diagnose it yet.

+ 05 Sep 2013; Tom Wijsman <TomWij@gentoo.org> +bcmail-1.38-r3.ebuild,
+ -bcmail-1.38-r2.ebuild:
+ Properly SLOT bcprov dependency with one that's exactly the same (except for
+ the SLOT) to resolve a blocker.
+ (http://forums.gentoo.org/viewtopic-p-73 ... ml#7389618)

Wait a few hours, sync again; then the revision bump will resolve the blocker.
