Gradle: create a single JAR with dependencies

问题

以下是已翻译的内容：

我正在将我们产品的构建从Ant迁移到Gradle，起初是从一个单一的项目开始的，然后出现了以下错误：

  1. > 无法解析配置项“：Shared:serverbase:compileClasspath”的所有文件。
  2.    > 找不到guava:guava:23.3-jre。
  3.      在以下位置搜索：
  4.        - https://jcenter.bintray.com/guava/guava/23.3-jre/guava-23.3-jre.pom
  5.        - file:/F:/pros/X/java/guava/guava-23.3-jre.xml
  6.      所需项：
  7.          项目 :Shared:serverbase

为什么它在寻找xml文件而不是jar文件？

以下是我的文件：
项目根目录中的build.gradle：

  1. buildscript {
  2.     repositories {
  3.         jcenter()
  4.         maven {
  5.             url "https://plugins.gradle.org/m2/"
  6.         }
  7.     }
  8.     dependencies {
  9.         classpath 'de.richsource.gradle.plugins:gwt-gradle-plugin:0.6' // gwt编译器插件
  10.     }
  11. }
  13. allprojects {
  15.     apply from: rootProject.file('libraries.gradle')
  16.     repositories {
  17.         jcenter()
  18.         ivy {
  19.             url  "file://${rootProject.projectDir}/ThirdParty/java/"
  20.             patternLayout  {
  21.                 artifact "[organization]/[module](-[revision])(.[ext])"
  22.             }
  23.         }
  24.     }
  25. }
  27. subprojects {
  28.     apply plugin: 'java-library'
  29.     
  30.     sourceCompatibility = '1.8'
  31.     targetCompatibility = '1.8'
  34.     compileJava.options.debugOptions.debugLevel = "lines,vars,source"
  35.     compileJava.options.compilerArgs += ["-nowarn"]
  36.     compileJava.options.debug = true
  37. }

此单一项目的build.gradle：

  1. sourceSets.main.java.srcDirs = ['src']
  3. dependencies {
  4.     implementation "guava:guava:${guavaVersion}"
  5.     implementation "slf4j:jul-to-slf4j:${slf4jVersion}"
  6.     implementation "logback:logback-classic:${logbackVersion}"
  8. }
  10. jar {
  11.     manifest {
  12.         attributes 'Class-Path': configurations.compileClasspath.collect { it.getName() }.join(' ')
  13.     }        
  14.            
  15. }

settings.gradle：

  1. rootProject.name = 'X'
  2. include 'Shared:serverbase'

libraries.gradle：

  1. ext {
  2. ...
  3.     guavaVersion = '23.3-jre'
  4. ...
  5. }

(某些内容已删除)

如果我将文件依赖项作为本地文件添加到build.gradle（https://stackoverflow.com/questions/20700053/how-to-add-local-jar-file-dependency-to-build-gradle-file）

  1. implementation files("guava-${guavaVersion}.jar")

我会得到大量类似“error: package org.slf4j does not exist”的错误，所以似乎根本没有满足依赖关系。
结果应该是一个带有已编译源代码的单一jar文件。

我是Gradle的初学者，请原谅我的不足之处。

英文:

I am migrating our product's build from Ant to Gradle, having started from a single project and got the following error:

  1. > Could not resolve all files for configuration ':Shared:serverbase:compileClasspath'.
  2.    > Could not find guava:guava:23.3-jre.
  3.      Searched in the following locations:
  4.        - https://jcenter.bintray.com/guava/guava/23.3-jre/guava-23.3-jre.pom
  5.        - file:/F:/pros/X/java/guava/guava-23.3-jre.xml
  6.      Required by:
  7.          project :Shared:serverbase

Why it is looking for xml-files instead of jar?

Here are my files:
build.gradle in project's root directory:

  1. buildscript {
  2.     repositories {
  3.         jcenter()
  4.         maven {
  5.             url "https://plugins.gradle.org/m2/"
  6.         }
  7.     }
  8.     dependencies {
  9.         classpath 'de.richsource.gradle.plugins:gwt-gradle-plugin:0.6' // gwt compiler plugin
  10.     }
  11. }
  13. allprojects {
  15.     apply from: rootProject.file('libraries.gradle')
  16.     repositories {
  17.         jcenter()
  18.         ivy {
  19.             url  "file://${rootProject.projectDir}/ThirdParty/java/"
  20.             patternLayout  {
  21.                 artifact "[organization]/[module](-[revision])(.[ext])"
  22.             }
  23.         }
  24.     }
  25. }
  27. subprojects {
  28.     apply plugin: 'java-library'
  29.     
  30.     sourceCompatibility = '1.8'
  31.     targetCompatibility = '1.8'
  34.     compileJava.options.debugOptions.debugLevel = "lines,vars,source"
  35.     compileJava.options.compilerArgs += ["-nowarn"]
  36.     compileJava.options.debug = true
  37. }

build.gradle of this single project:

  1. sourceSets.main.java.srcDirs = ['src']
  3. dependencies {
  4.     implementation "guava:guava:${guavaVersion}"
  5.     implementation "slf4j:jul-to-slf4j:${slf4jVersion}"
  6.     implementation "logback:logback-classic:${logbackVersion}"
  8. }
  10. jar {
  11.     manifest {
  12.         attributes 'Class-Path': configurations.compileClasspath.collect { it.getName() }.join(' ')
  13.     }        
  14.            
  15. }

settings.gradle:

  1. rootProject.name = 'X'
  2. include 'Shared:serverbase'

libraries.gradle:

  1. ext {
  2. ...
  3.     guavaVersion = '23.3-jre'
  4. ...
  5. }

(some content stripped)

And if I add file dependency to build.gradle as local file (https://stackoverflow.com/questions/20700053/how-to-add-local-jar-file-dependency-to-build-gradle-file)

  1. implementation files("guava-${guavaVersion}.jar")

I got tons of errors like 'error: package org.slf4j does not exist' so it seems that dependencies were not satisfied at all.
The outcome should be a single jar with compiled sources.

I am a novice in gradle, please forgive my unenlightenment.

得分: 1

你的Guava依赖项不正确。

从：

  1. implementation "guava:guava:${guavaVersion}"

更改为：

  1. implementation "com.google.guava:guava:${guavaVersion}"
英文:

Your Guava dependency is not correct.

Change from:

  1. implementation "guava:guava:${guavaVersion}"

To:

  1. implementation "com.google.guava:guava:${guavaVersion}"
