Error package serpapi does not exist

[hilmanski]

I tried to clone this repo and run the demo

git clone https://github.com/serpapi/google_search_results_java.git
cd google_search_results_java/demo
make run api_key=<your private key>

Upon running the make run, It shows

/bin/sh: ./gradlew: No such file or directory

So I run

gradle wrapper
chmod +x gradlew

Then try to run the program either with

make run api_key=...
// or
gradle guild

It shows this error

A similar thing happened when I tried to install/run the project with gradle from scratch.

Try running just plain make (or the all target) first.

My build fails at the end with

BUILD SUCCESSFUL in 3s
9 actionable tasks: 9 executed
see build/lib
gmake[1]: Leaving directory '/home/freaky/code/serpapi/google_search_results_java'
rm -rf libs/*.jar
cp ../build/libs/* libs
cp: libs is not a directory
gmake: *** [Makefile:21: dep] Error 1

There's no libs directory - it was presumably an empty directory, which git doesn't track. Creating it got me as far as it attempting to compile the demo after building deps but failing to find the serpapi package.

[Freaky]

Uncommenting implementation fileTree(dir: "./libs", includes: ['*.jar']) in gradle.build made the demo build.

Some deprecation warnings from gradle 8.2.1:

The RepositoryHandler.jcenter() method has been deprecated. This is scheduled to be removed in Gradle 9.0. JFrog announced JCenter's sunset in February 2021. Use mavenCentral() instead.

It worked using Maven: #22 (comment). There's a related PR which I didn't check: #3

Made it work when compiling from sources. Here's a patch:

Thank you @ilyazub @Freaky for sharing your findings. I'll try again later.

It may be due to my lack of understanding of Java. But I hope the readme file can be updated with a step-by-step process on how to install it:

• With Maven
• With Gradle

*separately. So customers can easily work with this as well.
