[jira] [Updated] (GROOVY-9964) Groovy 3 compilation is much slower
than Groovy 2 compilation for Gradle build scripts
[ https://issues.apache.org/jira/browse/GROOVY-9964?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sterling Greene updated GROOVY-9964:
------------------------------------
Description:
We've seen a large increase in Groovy compilation time from Groovy 2.5.12 -> 3.0.7 for Groovy DSL based build scripts.
In this generated 500 project Gradle build, you'll see...
5s script compilation time with Groovy 2.5:
[https://scans.gradle.com/s/vslkwp76qhdpu/performance/configuration?details=summary-script-compile]
18-19s script compilation time with Groovy 3.0 (3-4x worse):
[https://scans.gradle.com/s/pfudiyxhmtjfa/performance/configuration?details=summary-script-compile]
Please try the attached project with Gradle 7.0-milestone-2 (it uses Groovy 3.0.7).
[https://services.gradle.org/distributions/gradle-7.0-milestone-2-bin.zip]
The simplest way to force script compilation is to delete the script cache directory in ~/.gradle/caches/<gradle version>.
I couldn't attach the project, so I put a copy of it here: [https://github.com/big-guy/largeJavaMultiProject]
