|[aspectj-users] Incremental compiler enhancements
I've committed some changes discussed in https://bugs.eclipse.org/bugs/show_bug.cgi?id=221427 . What does this mean? It means snappier compiles for a workspace containing multiple AJDT projects that depend on each other, or depend on JDT projects. Your mileage may vary, but here are some numbers for working on a codebase containing 4 AJDT projects in a dependency chain. After adding a public method to a type in the project at the top of the dependency chain, the following numbers are for 'old' AJDT (averaged over a few runs): compile project one: 600ms compile project two: 1188ms (full build) compile project three: 9500ms (full build) compile project four: 3034ms (full build) total=14322ms Now with the changes in compile project one: 500ms compile project two: 210ms (incremental build) compile project three: 800ms (incremental build) compile project four: 300ms (incremental build) total=1810ms So total build time for the change is reduced by about 87%. For an AJDT project depending on a JDT project. I change a type in the JDT project but it is not a type that the AJDT project actually cares about (is not referenced): Old AJDT: Compile time of AJDT project = 6200ms (full build) New AJDT: Compile time of AJDT project = 500ms (incremental build) These changes are in AJDT dev build 184.108.40.206804031719 available now from the dev update site for Eclipse 3.3. feedback appreciated - good or bad. Andy.
