This tool copies and instruments a set of Java source files specified on the command line. The output of the instrumentation process is instrumented java source; you will then need to compile the instrumented source using a standard Java compiler.
Note: in Clover 3.1.x and older a class was named com.cenqua.clover.CloverInstr.
-i, --initstring <file>
Clover initstring. This is the full path to the dbfile that will be used to construct/update to store coverage data.
-s, --srcdir <dir>
Directory containing source files to be instrumented. If omitted individual source files should be specified on the command line.
-d, --destdir <dir>
Directory where Clover should place the instrumented sources. Note that files will be overwritten in the destination directory.
|-dc, --distributedCoverage <string>||Configuration for recording distributed pre-test coverage.|
Valid keys and default values are: ON | OFF |
|--dontFullyQualifyJavaLang||If set, then java.lang will not be used in instrumented source.|
-e, --encoding <encoding>
Specify the file encoding for source files. If not specified, the platform default encoding is used.
-f, --flushinterval <int>
Tell Clover how often to flush coverage data when using either "interval" or "threaded" flushpolicy. Value in milliseconds.
Set the instrumentation strategy. Valid values are "field" and "class". Default is "class".
|--instrlevel <string>||Set the instrumentation level. Valid values are "statement" and "method". Default is "statement".|
Whether to instrument lambda functions. Valid values are:
Since Clover 3.2.2. Default is "all" in 3.2.2-4.0.2 and "none" since 4.0.3.

-p, --flushpolicy <policy>
Tell Clover which flushpolicy to use when flushing coverage data to disk. Valid values are "directed", "interval" and "threaded". With "interval" or "threaded", you must also specify a flushinterval using -f. The default value is "directed".
|-mc --methodContext <name>=<regexp>||Defines a single custom method context. May be supplied more than once. (The \ may be needed to prevent shell expansion)|
|-sc --statementContext <name>=<regexp>||Defines a single custom statement context. May be supplied more than once. (The \ may be needed to prevent shell expansion)|
|-r, --relative||If specified, the initstring is treated as a relative path, rather than being converted to an absolute path. This is useful for distributed testing environments.|
If set to "
|--source <level>||Set the language level for Clover to use when parsing files.|
Source root path prefix that will be ignored when evaluating the test inclusion patterns. This parameter is optional; it specifies what is trimmed from the beginning of the file path before the tests Include/Exclude Pattern is evaluated (see parameters below). For example, if you specify
Enable verbose logging.
CloverInstr provides a simple API that accepts an array of strings representing the command line arguments and returns an integer result code. The following fragment illustrates use of the API:
Find all java source files in the directory "src", copy and instrument them into the directory "build/instr", which will be constructed if it does not exist. Coverage database "clover.db" is initialised.
Copy and instrument the source files "Money.java" and "IMoney.java" into the directory
"../../build/instr". Use the JDK1.4 grammar (i.e. support the 'assert' keyword).
