我尝试将本地.jar文件依赖项添加到构建中。gradle文件:
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')
}
您可以看到,我将.jar文件添加到这里的referencedLibraries文件夹:https://github.com/WalnutiQ/wAlnut/tree/version-2.3.1/referencedLibraries
但问题是,当我在命令行上运行命令:gradle build时,我得到以下错误:
error: package com.google.gson does not exist
import com.google.gson.Gson;
这是我的全部回购:https://github.com/WalnutiQ/wAlnut/tree/version-2.3.1
你可以添加jar做:
对于gradle,只需在build.gradle中放入以下代码:
dependencies {
...
compile fileTree(dir: 'lib', includes: ['suitetalk-*0.jar'])
...
}
对于maven,只需遵循以下步骤:
Intellij:
文件->项目结构->模块->依赖选项卡->点击+号-> jar和依赖->选择jar你想导入->ok ->应用(如果可见)->ok
记住,如果你在运行时得到任何java.lang.NoClassDefFoundError: Could not initialize class exception,这意味着jar中的依赖项没有安装,你必须在父项目中添加所有依赖项。
使用Kotlin DSL (build.gradle.kts)添加本地库文件的更多方法:
implementation(
files(
"libs/library-1.jar",
"libs/library-2.jar",
"$rootDir/foo/my-other-library.jar"
)
)
implementation(
fileTree("libs/") {
// You can add as many include or exclude calls as you want
include("*.jar")
include("another-library.aar") // Some Android libraries are in AAR format
exclude("bad-library.jar")
}
)
implementation(
fileTree(
"dir" to "libs/",
// Here, instead of repeating include or exclude, assign a list of paths
"include" to "*.jar",
"exclude" to listOf("bad-library-1.jar", "bad-library-2.jar")
)
)
上面的代码假设库文件位于模块的libs/目录中(这里的模块指的是build.gradle.kts所在的目录)。
如上所示,可以在include和exclude中使用Ant模式。
