A special task is provided to be able to view signature content SignatureInfoTask.
Task supposed to be used for:
- Curiosity: review default signatures content
- Check: review build signature (after build signature task)
- Optimize: review and optimize cache signature size to speed up check task
For example, to look java6 signature contents use:
dependencies {
signature 'org.codehaus.mojo.signature:java16-sun:1.0@signature'
}
task printSignature(type: ru.vyarus.gradle.plugin.animalsniffer.info.SignatureInfoTask) {
signature = configurations.signature
depth = 2
}It will print:
Signature java16-sun-1.0.signature (1.7 Mb) contains 18312 classes
com.sun 7115
javax.swing 1781
sun.awt 771
java.util 662
sun.nio 640
sun.security 632
...
Here you can see that java6 signature (1.7mb file) contains 18312 classes. Different depth values could be used to build different views. For example, with depth = 1:
Signature java16-sun-1.0.signature (1.7 Mb) contains 18312 classes
com 7115
sun 4636
javax 3327
java 2441
org 790
sunw 3
If you want to see alphabetical packages order, then disable sorting by size:
task printSignature(type: ru.vyarus.gradle.plugin.animalsniffer.info.SignatureInfoTask) {
signature = animalsnifferCacheMain.outputFiles
depth = 2
sortBySize = false
}Signature java16-sun-1.0.signature (1.7 Mb) contains 18312 classes
com.sun 7115
java.applet 5
java.awt 561
java.beans 155
java.io 126
java.lang 239
This may be handy for educational purposes.
Checking just created project signature:
animalsnifferSignature {
files sourceSets.main.output
}
task printSignature(type: ru.vyarus.gradle.plugin.animalsniffer.info.SignatureInfoTask) {
signature = tasks.animalsnifferSignature.outputFiles
depth = 1
}Checking signature caches for check task:
animalsniffer {
cache.enabled = true
}
task printSignature(type: ru.vyarus.gradle.plugin.animalsniffer.info.SignatureInfoTask) {
signature = animalsnifferCacheMain.outputFiles
depth = 2
sortBySize = false
}When multiple signatures used for the check, multiple info messages will be printed:
dependencies {
signature 'org.codehaus.mojo.signature:java16-sun:1.0@signature'
signature 'net.sf.androidscents.signature:android-api-level-14:4.0_r4@signature'
implementation 'org.slf4j:slf4j-api:1.7.25'
}Signature animalsnifferCacheMain_!java16-sun-1.0.sig (1.3 Mb) contains 13710 classes
