Upon startup, javac may report errors because (for instance) because it
received incorrect flags. These errors were not correctly parsed by the
JavaErrorParser and were never reported to the user.
This commit fixes this problem by adding a new parsing rule in
JavaErrorParser: errors that start with the prefix "javac:" are now
correctly parsed and reported to the user.
Fixessbt/sbt#2256
These options can only be given to a forked Java compiler. If we run a
local java compiler, we filter these options out and emit a warning.
Fixessbt/sbt#1968
In some cases, the local java compiler may report compilation errors,
but succeed in compiling the source files (for instance, if there are
encoding problems in the source). However, the command line javac will
report a failed compilation on the same input.
To have the local java compiler behave like the forked java compiler, we
now report the compilation as failed if error messages have been
registered during compilation.
Fixessbt/sbt#2228
The signatures of methods that have value classes as arguments or return
type change during the erasure phase. Because we only registered
signatures before the erasure, we missed some API changes when a class
was changed to a value class (or a value class changed to a class).
This commit fixes this problem by recording the signatures of method
before and after erasure.
Fixessbt/sbt#1171
sbt was reporting warning abouts inconsistent versions of dependencies
even if these dependencies didn't have the same configuration (as in
`provided` vs `compile`).
This commit fixes this problem by comparing the dependencies by
organization, artifact name and configuration.
Fixessbt/sbt#1933
This will avoid all clashes between modules that may have the same name
as other components of sbt, or two different compiler bridges that would
happen to have the same name.
Note that they won't be downloaded again, because the component compiler
will look for a previously-compiled version of the compiler bridge
before trying to fetch the sources again. If they've already been
downlaoded, then they have been compiled and a compiled version of the
compiler bridge already exists.
In order to restore reproducibility of builds, we no longer cascade over
the possibly available versions of the compiler bridge sources (a
specific version of the bridge sources may not be available one day, but
exist on the next day), but rather let the build definition configure
which module to use.
Fixessbt/sbt#2196
Because in most cases there aren't version-specific sources, we expect
the retrieval to fail a number of times before succeeding. This
generates a lot of noise in sbt's log, so the logs will now be shown if
and only all the versions fail.
