Hey I am trying to make some changes in the java sdk and test them How have you created the jar from the code bcoz I seem to run into a lot of ClassNotFound errors for OkHttp and Gson transitive dependencies

the project uses gradle and the distributed builds are built by jitpack page on jitpack example build log from jitpack the `build gradle` file has the build configuration You can also see the github actions workflows that build and test are you trying to import Gson or OkHttp into your project they are not exposed and are therefore not available if you are trying to use Gson and OkHttp directly you ll need to add them as dependencies to your project we have specified them as `implementation` dependencies rather than `api` dependencies here s a snippet from the gradle docs gt Dependencies appearing in the `api` configurations will be transitively exposed to consumers of the library and as such will appear on the compile classpath of consumers Dependencies found in the `implementation` configuration will on the other hand not be exposed to consumers and therefore not leak into the consumers compile classpath This comes with several benefits gt dependencies do not leak into the compile classpath of consumers anymore so you will never accidentally depend on a transitive dependency gt faster compilation thanks to reduced classpath size gt less recompilations when implementation dependencies change consumers would not need to be recompiled gt cleaner publishing when used in conjunction with the new `maven publish` plugin Java libraries produce POM files that distinguish exactly between what is required to compile against the library and what is required to use the library at runtime in other words don t mix what is needed to compile the library itself and what is needed to compile against the library you can learn more about that here this example JVM project implements the growthbook SDK it does not use OkHttp directly but implements the GBFeatureRepository which does It does however use its own version of Gson let me know if there s anything else i can answer

can you tell me more about your setup when you clone the repository are you able to run the gradle commands successfully how are you importing it into your project do you have any sample code you can share for your project that is trying to use it

after cloning I m running gradle jar task and importing it locally in the pom of another project by ``` lt dependency gt lt groupId gt com github growthbook lt groupId gt lt artifactId gt growthbook sdk java lt artifactId gt lt version gt main SNAPSHOT lt version gt lt scope gt system lt scope gt lt systemPath gt Users pranay garg Documents growthbook sdk java lib build libs lib main SNAPSHOT jar lt systemPath gt lt dependency gt ``` and just creating the ```Growthbook growthbook = new Growthbook ``` on running the project it throws the following error ```Exception in thread main java lang NoClassDefFoundError com google gson GsonBuilder at growthbook sdk java GrowthBookJsonUtils lt init gt GrowthBookJsonUtils java 28 at growthbook sdk java GrowthBookJsonUtils getInstance GrowthBookJsonUtils java 56 at growthbook sdk java GrowthBook lt init gt GrowthBook java 20 at com groww test TestApplication main TestApplication java 23 Caused by java lang ClassNotFoundException com google gson GsonBuilder at java base jdk internal loader BuiltinClassLoader loadClass BuiltinClassLoader java 581 at java base jdk internal loader ClassLoaders$AppClassLoader loadClass ClassLoaders java 178 at java base java lang ClassLoader loadClass ClassLoader java 522 ```

while if i import the published jar from jitpack and run the same code it works fine

best-quill-79210 · Answer

not sure why

better-magician-65629 · Answer

have you tried any of the following as a temporary workaround adding the 2 missing dependencies to your example project changing `implementation` to `api` in your cloned code to add the dependencies to your class path i m not sure you ll be able to access the dependencies this way without adding them to your classpath yourself this is a about this and according to system scope is deprecated in maven i haven t used this before but it looks like alternatives are the maven install plugin and `install install file` goal This is related to how you re resolving the dependencies locally

best-quill-79210 · Answer

it s working now apparently it was an issue with system scope I resolved it by publishing repo locally using ```gradle publishToMavenLocal```
