NAME
xbuild - Mono's tool to build MSBuild project files
SYNOPSIS
xbuild [option] [project-file]
DESCRIPTION
xbuild can be used to build MSBuild project files. Integrated Develop-
ment Environments like MonoDevelop and "Microsoft Visual Studio .NET"
use msbuild project file format.
xbuild takes the path of the project or solution file to build, as the
main argument. If no file is specified then it tries to build any so-
lution file or project file in the current directory, that has a *proj
extension.
OPTIONS
/target:T1[,TN]
List of targets to build
/property:Name=Value
Set or override project properties
/logger:<logger>
Custom logger to log build events
/toolsversion:version , /tv:version
Specify the toolset version to use.
Eg. /tv:4.0
This would cause 4.0 version of the Microsoft.Common.targets
(among others) to be used. This overrides
the value specified in a project file.
Valid values: 2.0, 3.0, 3.5 and 4.0
/verbosity:<level>
Logger verbosity level : quiet, minimal, normal, detailed, diag-
nostic
/validate
Validate the project file against the schema
/validate:<schema>
Validate the project file against the specified schema
/consoleloggerparameters:<params> , /clp:<params>
Parameters for the console logger : PerfomanceSummary, Summary,
NoSummary, NoItemAndPropertyList, Verbosity
/filelogger[n] , /fl[n]
Logs the output to a file, named 'msbuild.log' by default. If
the optional number 'n' is specified, then it logs to 'ms-
build[n].log' . Parameters for this logger, including the log
file name can be specified via a corresponding /flp[n] option.
Default verbosity for file loggers is 'detailed. 'n' can be be-
tween 1-9.
/fileloggerparameters[n]:<params> , /flp[n]:<params>
Parameters for a file logger. This implies a corresponding
/fl[n]. 'n' can be between 1-9, and is used to add upto 10 file
loggers. Parameters can be, besides the ones available for con-
sole logger:
LogFile=<file>
File to which the build log will be written.
Append If this is used, then the log file is appended to, else a
new one will be created.
Encoding=<encoding>
Encoding to use for the log file, eg. UTF-8, ASCII.
Eg: xbuild foo.csproj /flp:Verbosity=normal "/flp1:Log-
File=build.log;Append;Encoding=ASCII"
/nologo
Don't show the initial xbuild banner
/help Show xbuild usage
/version
Display xbuild version
ENVIRONMENT VARIABLES
XBUILD_EMIT_SOLUTION
If this variable is set, then the project file generated from a
solution file is emitted.
XBUILD_LOG_REFERENCE_RESOLVER
References are resolved by trying a list of assembly search
paths ($(AssemblySearchPaths)). If xbuild is unable to resolve
a reference, then it logs details of why the various search
paths failed. If this variable is set, then it logs the same
even for references that were resolved successfully. These logs
show up if the verbosity is set to detailed or higher.
MSBuildExtensionsPath
MSBuild extensions are usually installed in $(MSBuildExtension-
sPath), which xbuild resolves to $prefix/lib/mono/xbuild . When
used in Import, like:
<Import Project="$(MSBuildExtensionsPath)\TestTargets.tar-
gets"/>
xbuild tries various values for the msbuild property $(MS-
BuildExtensionsPath), in order:
1. Paths specified in the environment variable $MSBuildExten-
sionsPath.
2. /Library/Frameworks/Mono.framework/External/xbuild on Mac
OSX.
3. $XDG_CONFIG_HOME/xbuild/tasks (or Environment.Special-
Folder.ApplicationData)
4. $prefix/lib/mono/xbuild (default location)
Anywhere else in the project files, $(MSBuildExtensionsPath)
will always resolve to the default location. This is a xbuild-
only feature. This is also applicable for the properties $(MS-
BuildExtensionsPath32) and $(MSBuildExtensionsPath64), and the
environment variables have the corresponding names - MSBuildEx-
tensionsPath32/64 .
XBUILD_FRAMEWORK_FOLDERS_PATH
With ToolsVersion 4.0, projects can target arbitrary frameworks
referenced by TargetFrameworkMoniker, which is of the format:
Identifier,Version=<version>[,Profile=<profile>]
Eg. ".NETFramework,Version=v4.0"
The 3 parts of the moniker are given by the msbuild properties:
$(TargetFrameworkIdentifier), $(TargetFrameworkVersion) and
$(TargetFrameworkProfile)
This moniker maps to a framework description file on disk:
<framework_root>/Identifier/Version/[Profile]/Redis-
tList/FrameworkList.xml
This file is used to determine the path where to find the frame-
work assemblies for this particular framework.
Framework root here is configurable and is resolved in the fol-
lowing order:
1. Paths specified in the environment variable $XBUILD_FRAMEWORK_FOLDERS_PATH
2. /Library/Frameworks/Mono.framework/External/xbuild-frameworks on Mac OSX.
3. MSBuild property $(TargetFrameworkRoot)
4. $prefix/lib/mono/xbuild-frameworks (default location)
XBuild tries the paths given above, in order, till it finds a
FrameworkList.xml for the moniker. Running with /v:detailed or
higher verbosity will show the various paths that it tries.
The FrameworkList.xml itself just has a root element like:
<FileList Name=".NET Framework 3.5" TargetFrameworkDirec-
tory="..\..\..\..\3.5" IncludeFramework="v3.0">
</FileList>
Here the TargetFrameworkDirectory attribute specifies the direc-
tory where the assemblies for this particular framework can be
found. If this is not set, then the parent of the folder con-
taining the xml file is taken as the framework directory.
IncludeFramework attribute specifies the version of a framework
(under the *same* $(TargetFrameworkIdentifier)) which should be
included in the final list of Target framework directories.
XBUILD_COLORS
If this variable is set, it contains a string of the form
"type=foreground,type=.." that specifies which color to use to
display errors/warnings etc on some terminals. Type here can be:
errors, warnings, messages or events
events: These are project/target/task start and end event
messages.
The possible colors for foreground are: black, red, brightred,
green, brightgreen, yellow, brightyellow, blue, brightblue, ma-
genta, brightmagenta, cyan, brightcyan, grey, white and
brightwhite.
For example, you could set this variable from your shell:
export XBUILD_COLORS
XBUILD_COLORS=errors=brightred,warnings=blue
You can disable the built-in color scheme by setting this vari-
able to "disable".
NOTES
On Mac OSX, for locating pkg-config (.pc) files, xbuild additionally
looks in "/Library/Frameworks/Mono.framework/External/pkgconfig" .
