[英]How to include local jars into a fat jar using Gradle 6.3?
On a Linux machine running Java 8 and Gradle 6.3 I need to build a fat jar made of mix of libraries, some sourced from Maven Central, others from a local libs
directory located at the root of my repository, together with my build.gradle
and the gradlew
:在运行 Java 8 和 Gradle 6.3 的 Linux 机器上,我需要构建一个由混合库组成的胖 jar,一些来自 Maven Central,其他来自位于我的存储库根目录的本地libs
目录,以及我的build.gradle
和gradlew
:
apply plugin: 'java'
repositories {
mavenCentral()
flatDir {
dirs 'libs'
}
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
task copyLibs(type: Copy) {
from configurations.compile
into 'libs'
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
testImplementation "junit:junit:4.12"
}
After running ./gradlew clean build
and cd build/libs
, if I unzip myproject.jar
I can see that no dependencies have been included in the jar.运行./gradlew clean build
和cd build/libs
,如果我unzip myproject.jar
我可以看到 jar 中没有包含任何依赖项。
My end goal is to make my project executable as java -jar myproject.jar
.我的最终目标是使我的项目可执行为java -jar myproject.jar
。 How can I solve this?我该如何解决这个问题?
After unzipping your jar file check here for all dependencies.解压 jar 文件后,请在此处检查所有依赖项。
Your-Project --> BOOT-INF --> libs
by default, if your Gradle build is successful the jar files come here.
you can run java -jar then.然后你可以运行 java -jar 。
This is a build.gradle
that generates a fat jar including local dependencies:这是一个build.gradle
,它生成一个包含本地依赖项的胖 jar:
plugins {
id 'java'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
group 'com.mycompany.foo'
version '1.0'
jar {
archiveBaseName = 'myjarname'
archiveVersion = '0.1.0'
manifest {
attributes(
'Main-Class': 'com.mycompany.foo.Main'
)
}
from {
configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
}
}
repositories {
mavenCentral()
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
testImplementation'org.junit.jupiter:junit-jupiter-api:5.7.2'
testImplementation 'org.assertj:assertj-core:3.20.2'
}
