169NAME:
170 Java API Compliance Checker ($CmdName)
171 Check backward compatibility of a Java library API
172
173DESCRIPTION:
174 Java API Compliance Checker (JAPICC) is a tool for checking backward
175 binary/source compatibility of a Java library API. The tool checks class
176 declarations of old and new versions and analyzes changes that may break
177 compatibility: removed class members, added abstract methods, etc.
178
179 Break of the binary compatibility may result in crash or incorrect behavior
180 of existing clients built with an old library version if they run with a
181 new one. Break of the source compatibility may result in recompilation
182 errors with a new library version.
183
184 The tool is intended for developers of software libraries and maintainers
185 of operating systems who are interested in ensuring backward compatibility,
186 i.e. allow old clients to run or to be recompiled with newer library
187 versions.
188
189 This tool is free software: you can redistribute it and/or modify it
190 under the terms of the GNU LGPL or GNU GPL.
191
192USAGE:
193 $CmdName [options]
194
195EXAMPLE 1:
196 $CmdName OLD.jar NEW.jar
197
198EXAMPLE 2:
199 $CmdName -lib NAME -old OLD.xml -new NEW.xml
200 OLD.xml and NEW.xml are XML-descriptors:
201
202 <version>
203 1.0
204 </version>
205
206 <archives>
207 /path1/to/JAR(s)/
208 /path2/to/JAR(s)/
209 ...
210 </archives>
211
212INFORMATION OPTIONS:
213 -h|-help
214 Print this help.
215
216 -v|-version
217 Print version information.
218
219 -dumpversion
220 Print the tool version ($TOOL_VERSION) and don't do anything else.
221
222GENERAL OPTIONS:
223 -l|-library NAME
224 Library name (without version).
225
226 -old|-d1 PATH
227 Descriptor of the 1st (old) library version.
228 It may be one of the following:
229
230 1. Java archive (*.jar)
231 2. XML-descriptor (VERSION.xml file):
232
233 <version>
234 1.0
235 </version>
236
237 <archives>
238 /path1/to/JAR(s)/
239 /path2/to/JAR(s)/
240 ...
241 </archives>
242
243 ...
244
245 3. API dump generated by -dump option
246
247 If you are using *.jar as a descriptor then you should
248 specify version numbers with -v1 and -v2 options too.
249 If version numbers are not specified then the tool will
250 try to detect them automatically.
251
252 -new|-d2 PATH
253 Descriptor of the 2nd (new) library version.
254
255EXTRA OPTIONS:
256 -client|-app PATH
257 This option allows to specify the client Java archive that should be
258 checked for portability to the new library version.
259
260 -binary|-bin
261 Show \"Binary\" compatibility problems only.
262 Generate report to \"bin_compat_report.html\".
263
264 -source|-src
265 Show \"Source\" compatibility problems only.
266 Generate report to \"src_compat_report.html\".
267
268 -v1|-version1 NUM
269 Specify 1st API version outside the descriptor. This option is needed
270 if you have prefered an alternative descriptor type (see -d1 option).
271
272 In general case you should specify it in the XML descriptor:
273 <version>
274 VERSION
275 </version>
276
277 -v2|-version2 NUM
278 Specify 2nd library version outside the descriptor.
279
280 -vnum NUM
281 Specify the library version in the generated API dump.
282
283 -s|-strict
284 Treat all API compatibility warnings as problems.
285

291
292 -skip-internal-packages PATTERN
293 Do not check packages matched by the pattern.
294
295 -skip-internal-types PATTERN
296 Do not check types (classes and interfaces) matched by the pattern.
297
298 -dump|-dump-api PATH
299 Dump library API to gzipped TXT format file. You can transfer it
300 anywhere and pass instead of the descriptor. Also it may be used
301 for debugging the tool.
302
303 -classes-list PATH

305 of classes that should be checked, other classes will not be checked.
306

309 classes annotated by the annotations from the list. Other classes
310 will not be checked.
311

313 Skip checking of classes annotated by the annotations in the list.
314
315 -skip-deprecated
