The CloudBees Accelerator Javadoc caching feature can improve build performance by caching and reusing Javadoc files.
To enable Javadoc caching for a specific rule, add the following before that rule:
#pragma jobcache javadoc
Alternatively, you can mention the target again in a separate makefile:
#pragma jobcache javadoc mytarget :
By default, the cache becomes obsolete when
*.java files are added to or removed from directories that are read by the rule body. You can override this default wildcard pattern by invoking:
#pragma jobcache javadoc -readdir pattern
pattern is the pattern that you want to ignore. You can use multiple wildcard (glob) patterns.
eMake permanently ignores the effect on a given result of certain special files that might have existed when it was created, in all cases using the names they would have had at that time:
Anything in ".emake" or whatever alternative directory you specified using
Client-side eMake debug log (as specified by
Annotation file (as specified by
History file (as specified by
|-hdf arguments are removed from consideration for which cache slot to use.|
If you want to delete the cache, see Deleting the Cache.
For debugging information, see Debugging.
The following Javadoc invocations are not supported:
Javadoc is invoked indirectly, such as through a wrapper script
The rule body recursively invokes eMake
If Javadoc is named something other than "javadoc"
Javadoc caching is sensitive to changes in
*.javawildcard outcomes in directories that are actually read by the job, and any new subdirectories thereof.
#pragma jobcache …cannot be applied to patterns as such, only to explicitly specified targets (though the commands might be provided by a pattern).
Windows is not supported.
The Javadoc caching feature does not detect the need to rebuild Javadoc files in these cases:
Changes to input files and programs that are used by a rule body but that Accelerator does not virtualize (because they are not located under
Changes to non file system, non-registry aspects of the environment, for example, the current time of day
If a rule job checks the existence or timestamp of a file without reading it, Javadoc caching might not invalidate its cached result when the file is created, destroyed, or modified. However, Javadoc caching will detect when files matching "*.java" (or the pattern specified by "-readdir") are added or removed from directories read by the rule body, or any new subdirectories thereof. In that case eMake will rerun Javadoc.
