Using sempre in a Gradle java project

[stbusch]

Hi,
I guess for doing so I have to add dependencies to the gradle build file,
somehow like this:
dependencies {
implementation (group: 'com.github.percyliang', name: 'sempre', version: '2.4')
}
but when trying to build, I get an error message saying sempre couldn't be found.
Should I use another version number? Any other idea what is going wrong?
jitpack.io repository (for accessing GitHub) is already added.

Thanks for attention,
Stefan

Hmm.. Looks like v2.4 has not been released. Could you try setting the version to "v2.3" (with "v")?

[stbusch]

Thanks, but I get:

Could not find com.github.percyliang:sempre:v2.3.

I'm trying to apply step 2 from these instructions:
https://github.com/jitpack/jitpack.io
What else could I try for "version"?

[ppasupat]

Maybe try the master snapshot?

implementation 'com.github.percyliang:sempre:master-SNAPSHOT'

Also doesn't work

hi, the issue might be that jitpack VMs do not have ruby installed. From the error log on jitpack:

/home/jitpack/build/build.xml:18: Execute failed: java.io.IOException: Cannot run program "./scripts/extract-module-classes.rb" (in directory "/home/jitpack/build"): error=2, No such file or directory
	at java.lang.ProcessBuilder.start(ProcessBuilder.java:1048)

[timobaumann]

actually, there's no need to run the ruby script just for building, is there?
(I guess that should be fixed in the ant-based build-process.)

[ppasupat]

The ant file actually calls scripts/extract-module-classes.rb to generate module-classes.txt, which lists the classes associated with each module. I believe this is used for parsing the command line flags into Options.

[timobaumann]

can the call to ruby be restricted (via ant-logic) to only be run in case that one wants to run sempre (rather than just build the library)?
