msbuild: error MSB4019: The imported project ... was not found

[ryandesign (Ryan Carsten Schmidt)]

​msbuild doesn't build:

/opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_devel_msbuild/msbuild/work/mono-msbuild-560b1ca/mono/build/update_bundled_bits.proj(2,5): error MSB4019: The imported project "/opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_devel_msbuild/msbuild/work/mono-msbuild-560b1ca/mono/build/DotnetBitsVersions.props" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.

Build FAILED.

The filename on disk actually has a capital "N": DotNetBitsVersions.props

The buildbot workers' filesystems are case-sensitive.

It was fixed in ​https://github.com/mono/msbuild/commit/d482afec88b303303905958653fa906e65b2a1c2. Could you update the port to a newer version?

Dang, a different problem with case-sensitivity seems to ​still exist.

As far as I can tell, msbuild is looking for License.txt, but only LICENSE.txt exists.
I do not know how to fix this.
msbuild is quite adamant that it be allowed to download anything it thinks it needs during the build phase.
Some time ago, I tried to download dependencies manually with no luck.

I think the license issue was fixed in ​https://github.com/dotnet/arcade/commit/6899e98770d05659585c6e25bef305a381bcc576

So I guess we'll just have to wait for a new release.

Replying to MarcusCalhoun-Lopez:

No license file found in '/opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_devel_msbuild/msbuild/work/mono-msbuild-619cbd0/'.

​This problem appears to have resurfaced.

I just ran "sudo port install msbuild" ... and it failed with the error described in this original bug report.

msbuild/work/mono-msbuild-70bf671/mono/build/update_bundled_bits.proj is trying to import DotnetBitsVersions.props ... but the file is named DotNetBitsVersions.props (note the CAPITAL N)
