IContract Task

icontract

Description

Instruments Java classes with iContract DBC preprocessor.
The task can generate a properties file for iControl, a graphical user interface that lets you turn on/off assertions. iControl generates a control file that you can refer to from this task using the controlfile attribute.

Parameters

Attribute	Description	Required
srcdir	Location of the java files.	Yes
instrumentdir	Indicates where the instrumented source files should go.	Yes
repositorydir	Indicates where the repository source files should go.	Yes
builddir	Indicates where the compiled instrumented classes should go. Defaults to the value of instrumentdir. NOTE: Don't use the same directory for compiled instrumented classes and uninstrumented classes. It will break the dependency checking. (Classes will not be reinstrumented if you change them).	No
repbuilddir	Indicates where the compiled repository classes should go. Defaults to the value of repositorydir.	No
pre	Indicates whether or not to instrument for preconditions. Defaults to `true` unless controlfile is specified, in which case it defaults to `false`.	No
post	Indicates whether or not to instrument for postconditions. Defaults to `true` unless controlfile is specified, in which case it defaults to `false`.	No
invariant	Indicates whether or not to instrument for invariants. Defaults to `true` unless controlfile is specified, in which case it defaults to `false`.	No
failthrowable	The full name of the Throwable (Exception) that should be thrown when an assertion is violated. Defaults to `java.lang.Error`	No
verbosity	Indicates the verbosity level of iContract. Any combination of `error,warning,note,info,progress,debug` (comma separated) can be used. Defaults to `error*`	No
quiet	Indicates if iContract should be quiet. Turn it off if many your classes extend uninstrumented classes and you don't want warnings about this. Defaults to `false`	No
updateicontrol	If set to true, it indicates that the properties file for iControl in the current directory should be updated (or created if it doesn't exist). Defaults to `false`.	No
controlfile	The name of the control file to pass to iContract. Consider using iControl to generate the file. Default is not to pass a file.	Only if `updateicontrol=true`
classdir	Indicates where compiled (unistrumented) classes are located. This is required in order to properly update the icontrol.properties file, not for instrumentation.	Only if `updateicontrol=true`
targets	Name of the file that will be generated by this task, which lists all the classes that iContract will instrument. If specified, the file will not be deleted after execution. If not specified, a file will still be created, but it will be deleted after execution.	No

Note: iContract will use the java compiler indicated by the project's build.compiler property. See documentation of the Javac task for more information. Nested includes and excludes are also supported.

Note: iContract will use the java compiler indicated by the project's build.compiler property. See documentation of the Javac task for more information.

Nested includes and excludes can be done very much the same way as any subclass of MatchingTask.

Example:

 <icontract
    srcdir="${build.src}"
    instrumentdir="${build.instrument}"
    repositorydir="${build.repository}"
    builddir="${build.instrclasses}"
    updateicontrol="true"
    classdir="${build.classes}"
    controlfile="control"
    targets="targets"
    verbosity="error*,warning*"
    quiet="true"

    <classpath refid="compile-classpath"/>
