How to add local .jar file dependency to build.gradle file?
So I have tried to add my local .jar file dependency to my build.gradle file:
apply plugin: 'java'
sourceSets {
main {
java {
srcDir 'src/model'
}
}
}
dependencies {
runtime files('libs/mnist-tools.jar', 'libs/gson-2.2.4.jar')
runtime fileTree(dir: 'libs', include: '*.jar')
}
And you can see that I added the .jar files into the referencedLibraries folder here: https://github.com/WalnutiQ/wAlnut/tree/version-2.3.1/referencedLibraries
But the problem is that when I run the command: gradle build on the command line I get the following error:
error: package com.google.gson does not exist
import com.google.gson.Gson;
Here is my entire repo: https://github.com/WalnutiQ/wAlnut/tree/version-2.3.1
If you really need to take that .jar from a local directory,
Add next to your module gradle (Not the app gradle file):
repositories {
flatDir {
dirs 'libs'
}
}
dependencies {
compile name: 'gson-2.2.4'
}
However, being a standard .jar in an actual maven repository, why don't you try this?
repositories {
mavenCentral()
}
dependencies {
compile 'com.google.code.gson:gson:2.2.4'
}
根据文档，为本地jar依赖项使用相对路径，如下所示：
dependencies {
compile files('libs/something_local.jar')
}
You could also do this which would include all JARs in the local repository. This way you wouldn't have to specify it every time.
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
}
