Gradle very slow in my linux mint

Help/Discuss
1

Hi All,

I am trying to execute a simple gradle task on my linux mint. The task takes 5 seconds to execute which is very huge time for a simple hello world task

This is my build.gradle file

task hello {
group ‘Hello’
description ‘This is a hello world example of the task’

doLast {
println ‘I am the hello task’
}
}

This is my task output
gradle hello

Task :hello
I am the hello task

BUILD SUCCESSFUL in 5s
1 actionable task: 1 executed

Please note: I ran the task several times but still the same 5s run time for this simple task

This is my gradle --status output
gradle --status
PID STATUS INFO
25910 IDLE 4.4.1
20367 STOPPED (by user or operating system)

Only Daemons for the current Gradle version are displayed. See The Gradle Daemon - Gradle User Guide Version 4.4.1

This is my gradle version
gradle --version

Gradle 4.4.1

Gradle has a built in profiler that may help you narrow down where time is being spent.

Hi Chris,

Thanks a lot responding to my question.

Thats quite brilliant the profiling tool

I could see that the startup is taking huge time

Description Duration
Total Build Time 5.474s
Startup 5.443s
Settings and BuildSrc 0.001s
Loading Projects 0.003s
Configuring Projects 0.003s
Task Execution 0.007s

And when I run with the debug option enabled I could see the following piece of code takes the time to execute

I have docker installed by the way in my machine

I think I found the cause.

This is because of the openjdk

when I change the Java in my machine to oracle Java

Everything worked fine and gradle seems to be fast
