Even with `publishArtifact := false` the user is still forced to define a (dummy) resolver that's never used, e.g. `publishTo := { Some("publishMeNot" at "https://publish/me/not") }`
Otherwise the following error is thrown:
```
publish
[error] java.lang.RuntimeException: Repository for publishing is not specified.
[error] at scala.sys.package$.error(package.scala:27)
[error] at sbt.Classpaths$.$anonfun$getPublishTo$1(Defaults.scala:2436)
[error] at scala.Option.getOrElse(Option.scala:121)
[error] at sbt.Classpaths$.getPublishTo(Defaults.scala:2436)
[error] at sbt.Classpaths$.$anonfun$ivyBaseSettings$48(Defaults.scala:1917)
```
This is to avoid it initialising Log4J2 (via SLF4J), which we initialise
ourselves programmatically in LogExchange. Also there's no need to
removeAll in initialState.
Fixes#3787
Fixessbt/sbt#3804
Inside the if, it seems like bunch of variables were set to blank.
Using delayed expansion seems to fix this. This is confirmed by the newly added test.
Ref https://github.com/sbt/io/pull/96
Under RFC 8089, both u1 and u3 are legal, but many of the other platforms expect traditional u3.
This will increase the compatibility/usability of sbt server, for example to integrate with Vim.
FileInfo is used to wrap information like last modified time on
files that may or may not exist. Arguably, that does not make
much sense: the non-existent files should not lead to modification
file information, hashes, and a persistent serialized version of
the resulting meaningless information. However, considering that
the FileInfo information is serialized and saved, it is necessary
to preserve compatibility at this stage. Therefore the modification
time is explicitly set to zero for those files that do not exist
when each FileInfo is built.
Although in theory the fix in #3776 should be preferable to
synchronize templateStats() manually, it turns out that we
still get errors in some tests. So, reverting to a
synchronized section while we investigate.
This reverts commit ee90917cc4.
Currently the server will try to start even if there are existing sbt sessions. This causes the second session to take over the server for Unix domain socket.
This adds a check before the server comes up and make sure that the socket is not taken.
