java - 更改 "bootJar"目标目录

Question

刚接触 gradle，面临 Jenkins 管道中的问题。整个构建成功，但无法找到我的 spring 项目的可启动 jar。如果可以的话请告诉我如何将 jar 从 target/lib/移动到/target 文件夹。

下面是我的build.gradle

import io.swagger.codegen.DefaultGenerator
import io.swagger.codegen.config.CodegenConfigurator

buildscript {
    ext {
        springBootVersion = '2.0.5.RELEASE'
        jacocoWorkspaceDirectory = "/jacoco/"
    }
    repositories {
        mavenLocal()
        maven { url "http://repo.maven.apache.org/maven2" }
    }
    dependencies {

    }
}

P.S-我尝试了project.buildDir，但是将build更改为target，jar仍然在target/lib目录中生成。

Answer 1

在 Configuring executable archive packaging Spring Boot Gradle Plugin Reference Guide 部分我们可以读到:

The BootJar and BootWar tasks are subclasses of Gradle’s Jar and War tasks respectively. As a result, all of the standard configuration options that are available when packaging a jar or war are also available when packaging an executable jar or war.

考虑到这一点，如果我们查看 Gradle's Jar plugin它有文档destinationDirectory属性表示存档将放置的目录。

尝试根据以下内容更新您的 build.gradle 脚本:

bootJar {
  destinationDirectory = file(project.buildDir)
}

这应该可以解决问题。
