问题
After upgrading my project to enable Jack and Java8 features, my 16gb macbook can't seem to build my project anymore. I see the memory usage getting higher and higher but the process gets stuck at the same point always.
My Gradle console:
Executing tasks: [:app:assembleDebug]
Configuration on demand is an incubating feature.
Incremental java compilation is an incubating feature.

Before using Jack the compiler would build in less than 20s or so, what might be wrong ?? Thanks
回答1:
Seems like this has been triaged acknowledged as a "Critical" bug and hopefully the "2.4" Gradle plugin should bring us faster build times :)
Not that this may make a major difference, but try updating the app's build.gradle with the following
android {
.
.
.
defaultConfig {
.
.
.
.
jackOptions {
enabled true
additionalParameters('jack.incremental': 'true')
}
.
.
}
dexOptions {
javaMaxHeapSize '4096m'
}
compileOptions {
incremental true
.
.
.
}
}
回答2:
Try increasing the Java Heap Size
dexOptions {
javaMaxHeapSize "4g"
}
With a 16gb MacBook Pro you can even bump it up to 8g
