API Use Ant Task
Purpose
This task runs a complete search of a given baseline to determine a producer-centric report of API usage.
The analysis does not include bundles that are not API Tools enabled.
Usage
Description
The name of the ant task is: apitooling.apiuse. To be used, the jar file apitooling-ant.jar has to be on the ant
classpath.

Attribute

Description
|
Required
|
| baseline |
This attribute specifies the location of the current product or baseline that you want to search for API usage to.
It can be a .zip, .jar, .tgz, .tar.gz file, or a directory that corresponds to a collection of bundles.
The location is specified using an absolute path. |
Yes |
| scope |
This attribute specifies the location of the current product or baseline that you want to search against for API usage.
It can be a .zip, .jar, .tgz, .tar.gz file, or a directory that corresponds to a collection of bundles. If no scope is provided
the baseline will act as itself and the search scope.
The location is specified using an absolute path. |
No |
| report |
Set the output location where the reports will be generated.
Once the task is completed, reports are available in this directory using a hierarchical structure. A sub-folder is created
for each component that has another bundle that references it. Each sub-folder contains a file called "[bundlename].xml". Within
this folder is another sub-folder (named "[referencing bundle name].xml") for each bundle that references the bundle of the containing folder.
Inside the referencing bundle folder is one of three sub-folders (API, PRIVATE or OTHER) which contain type, method or field references of that kind.
Two other special files are written into the report directory, which are "not_searched.xml" and "no_apidescription.xml" and they contain
information about bundles from the baseline that were not search for usage information and those that did not have an .api_description files in them, respectively.
The location is specified using an absolute path.
For example:
root
|
+-- "not_searched.xml"
+-- "no_apidescription.xml"
+-- bundle name with usage
|
+--referencing bundle name
|
+-- [API or PRIVATE or OTHER]
|
+--[type_ or method_ or field_]references.xml
|
Yes |
| proceedonerror |
If the use search should try to continue if an error is encountered.
Default is false. |
No |
| includenonapiprojects |
If non-API enabled projects should be allowed in the search scope.
Default is false. |
No |
| includesystemlibraries |
If system libraries should be allowed in the search scope.
Default is false. |
No |
| considerinternal |
If internal references should be considered during the search.
Default is false. |
No |
| considerapi |
If API references should be considered during the search.
Default is false. |
No |
| eefile |
Set the execution environment file to use.
By default, an execution environment file corresponding to a JavaSE-1.6 execution environment is used.
The format of the file is described in this
wiki page.
The file is specified using an absolute path. |
No |
| excludelist |
Set the exclude list location.
The exclude list is used to know what bundles should excluded from the search scope during a search.
The lines that start with '#' are ignored from the excluded elements.
Regular expressions can be used in the listing but must be prefixed with 'R:'. For example
R:org.eclipse.*
The location is specified using an absolute path.
The format of the exclude list file looks like this:
# DOC BUNDLES
R:org.eclipse.*.doc.*
# NON-ECLIPSE BUNDLES
com.ibm.icu
com.jcraft.jsch
javax.servlet
javax.servlet.jsp
...
|
No |
| debug |
Set the debug value.
The possible values are: true, false
Default is false. |
No |
Examples
<apitooling.apiuse
baseline="/eclipse/eclipse.tar.gz"
scope="/eclipse/jdt_only.tar.gz"
proceedonerror="true"
includenonapiprojects="false"
includesystemlibraries="false"
report="/eclipse/apiuse-both/XML"
considerinternal="true"
considerapi="true"
eefile=""
excludelist="/eclipse/excludelist.txt"
debug="true"
/>
This will run the task creating *.xml files inside the folder /eclipse/apiuse-both/XML.
It will use the exclude list located in /eclipse/excludelist.txt to reduce the scope of the search.
If debug is enabled, some debug tracing will show up in the ant console.
