Description Yuan Liao (Leo3418) 2022-01-18 20:12:18 UTC

(Note: This is a bug for an ebuild submitted by myself)

dev-java/ant-core-1.10.9-r1 forbids USE="doc" on arm and arm64 architectures, which is a regression because dev-java/ant-core-1.10.9 allows it on them.

The reason is that one dependency required to build the documentation, dev-java/sun-jai-bin, is not keyworded on those architectures yet.  The dependency is required to resolve https://bugs.gentoo.org/780531.


From lines 26-31 in ant-core-1.10.9-r1.ebuild:

# Some dependencies for building Javadoc are unavailable on these architectures
REQUIRED_USE="doc? ( !arm !arm64 )"

CDEPEND=">=virtual/jdk-1.8:*"
DEPEND="${CDEPEND}
	doc? ( !arm? ( !arm64? (


Attempting to install dev-java/ant-core-1.10.9-r1 with USE="doc" on those architectures might give an error like:

$ USE="doc" emerge --pretend '=dev-java/ant-core-1.10.9-r1'

These are the packages that would be merged, in order:

Calculating dependencies |

!!! Problem resolving dependencies for =dev-java/ant-core-1.10.9-r1
... done!

!!! The ebuild selected to satisfy "=dev-java/ant-core-1.10.9-r1" has unmet requirements.
- dev-java/ant-core-1.10.9-r1::gentoo USE="doc (prefix) -source"

  The following REQUIRED_USE flag constraints are unsatisfied:
    doc? ( !arm64 )

  The above constraints are a subset of the following complete expression:
    doc? ( !arm !arm64 )


With dev-java/ant-core-1.10.9:

$ USE="doc" emerge --pretend '=dev-java/ant-core-1.10.9'

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N     ] dev-java/ant-core-1.10.9  USE="doc -source"

FWIW, we should use masks for stuff like this to allow easy overriding for example, not REQUIRED_USE.

Makes sense, thanks for the tip!
