28 # mx is a command line tool inspired by mvn (http://maven.apache.org/) | |
29 # and hg (http://mercurial.selenic.com/). It includes a mechanism for | |
30 # managing the dependencies between a set of projects (like Maven) | |
31 # as well as making it simple to run commands | |
32 # (like hg is the interface to the Mercurial commands). | |
33 # | |
34 # When launched, mx looks for a mx configuration (i.e. a directory named 'mx') | |
35 # in the current working directory. This is the primary mx configuration. Any | |
36 # other mx configurations are included mx configurations. | |
37 # | |
38 # If an mx configuration exists, then the following files in the configuration | |
39 # are processed (if they exist): | |
40 # | |
41 # projects - Lists projects, libraries and dependencies between them | |
42 # commands.py - Extensions to the commands launchable by mx. This is only processed | |
43 # for the primary mx configuration. | |
44 # includes - Other directories containing mx configurations to be loaded. | |
45 # This is a recursive action. | |
46 # env - A set of environment variable definitions. | |
47 # | |
48 # The MX_INCLUDES environment variable can also be used to specify | |
49 # other directories containing mx configurations. | |
50 # This value of this variable has the same format as a Java class path. | |
51 # | |
52 # The includes and env files are typically not put under version control | |
53 # as they usually contain local filesystem paths. | |
54 # | |
55 # The projects file is like the pom.xml file from Maven except that | |
56 # it is in a properties file format instead of XML. Each non-comment line | |
57 # in the file specifies an attribute of a project or library. The main | |
58 # difference between a project and a library is that the former contains | |
59 # source code built by the mx tool where as the latter is an external | |
60 # dependency. The format of the projects file is | |
61 # | |
62 # Library specification format: | |
63 # | |
64 # library@<name>@<prop>=<value> | |
65 # | |
66 # Built-in library properties (* = required): | |
67 # | |
68 # *path: the file system path for the library to appear on a class path | |
69 # urls: a comma seperated list of URLs from which the library can be downloaded | |
70 # optional: if "true" then this library will be omitted from a class path if it doesn't exist on the file system and no URLs are specified | |
71 # | |
72 # Project specification format: | |
73 # | |
74 # project@<name>@<prop>=<value> | |
75 # | |
76 # The name of a project also denotes the directory it is in. | |
77 # | |
78 # Built-in project properties: | |
79 # | |
80 # *sourceDirs: a comma separated list of source directoriy names (relative to the project directory) | |
81 # dependencies: a comma separated list of the libraries and project the project depends upon (transitive dependencies may be omitted) | |
82 # checkstyle: the project whose Checkstyle configuration (i.e. <project>/.checkstyle_checks.xml) is used | |
83 # | |
84 # Other properties can be specified for projects and libraries for use by extension commands. | |
85 # | |
86 # Values can use environment variables with Bash syntax (e.g. ${HOME}). | |
