小編給大家分享一下IDEA中Gradle如何刪除多余無用依賴,希望大家閱讀完這篇文章之后都有所收獲,下面讓我們一起去探討吧!
項目中經過很久開發(fā),會有很多當初引入后來又不再使用的依賴,靠肉眼很難分辨刪除。
這時候,我們可以使用分析無用依賴插件進行處理:gradle-lint-plugin
注意: 他可能存在刪除錯誤的引用依賴,需要刪除后進行檢查和測試
并且,這里僅支持單模塊項目,如果是多模塊項目請參考官方文檔進行處理
官方文檔地址: https://github.com/nebula-plugins/gradle-lint-plugin/wiki
在項目的 build.gradle
中引用該插件, 最新版本號可以 點擊這里查看:
plugins { id 'nebula.lint' version '17.7.0' }
如何你項目中本身已經有插件,則可以在后面追加,例如我的:
plugins { id 'org.springframework.boot' version '2.3.5.RELEASE' id 'io.spring.dependency-management' version '1.0.10.RELEASE' id 'java' id 'nebula.lint' version '17.7.0' }
在 build.gradle
應用 該插件,并在任意位置,配置檢測規(guī)則:
apply plugin :"nebula.lint" gradleLint.rules=['unused-dependency']
IDEA
使用 Gradle 進行重新載入項目,則會出現(xiàn) Lint
菜單, 如下圖所示:
點擊 lint -> generateGradleLintReport
, 可以生成報告。
報告僅保留不同類型的省略結果,可以看到有以下四種報告結果:
one or more classes are required by your code directly (no auto-fix available)
this dependency is unused and can be removed
this dependency should be removed since its artifact is empty (no auto-fix available)
this dependency is a service provider unused at compileClasspath time and can be moved to the runtimeOnly configuration (no auto-fix available)
其中, this dependency is unused and can be removed
表示可以刪除的依賴。
Executing 'generateGradleLintReport'...
> Task :generateGradleLintReport
Generated a report containing information about 83 lint violations in this project
> Task :autoLintGradle
This project contains lint violations. A complete listing of the violations follows.
Because none were serious, the build's overall status was unaffected.
warning unused-dependency one or more classes in org.mockito:mockito-core:3.3.3 are required by your code directly (no auto-fix available)
warning unused-dependency this dependency should be removed since its artifact is empty (no auto-fix available)
build.gradle:59
implementation 'org.springframework.boot:spring-boot-starter-actuator'
warning unused-dependency this dependency is a service provider unused at compileClasspath time and can be moved to the runtimeOnly configuration (no auto-fix available)
build.gradle:69
compileOnly 'org.projectlombok:lombok'
warning unused-dependency this dependency is unused and can be removed
build.gradle:101
compile group: 'ch.qos.logback', name: 'logback-core', version: '1.2.3'
? 83 problems (0 errors, 83 warnings)
To apply fixes automatically, run fixGradleLint, review, and commit the changes.
我們可以看到報告的最后一句話,
To apply fixes automatically, run fixGradleLint, review, and commit the changes.
最后,可以執(zhí)行 fixGradleLint
自動刪除無用依賴。
修復報告如下,我們可以看到除了無用的依賴,還有一些其他的依賴也被刪除了,原因是因為,他認為我們可以直接引入其對應的依賴而不是整個依賴包。
例如,compile group: 'com.baomidou', name: 'mybatis-plus-boot-starter', version: '3.3.1'
中我們只用了整個 starter 包的一部分依賴,可以僅依賴這一部分依賴,而不是整個 starter 包。這個也可以不按照他的推薦,直接手動選擇保留。
Executing 'fixGradleLint'...
> Task :compileJava
> Task :processResources UP-TO-DATE
> Task :classes
> Task :compileTestJava
> Task :fixGradleLint
This project contains lint violations. A complete listing of my attempt to fix them follows. Please review and commit the changes.
needs fixing unused-dependency one or more classes in com.baomidou:mybatis-plus-core:3.3.1 are required by your code directly

build.gradle:105

build.gradle:106

compile 'org.mybatis:mybatis-typehandlers-jsr310:1.0.2'
build.gradle:112
testImplementation 'org.springframework.security:spring-security-test'
Corrected 17 lint problems
Lombok 是一個編譯時自動生成 Getter/Setter 和構造器的工具。
Nebula Lint 依舊會檢測無用的依賴,日志如下:
> Task :lintGradle FAILED
This project contains lint violations. A complete listing of the violations follows.
Because none were serious, the build's overall status was unaffected.
warning unused-dependency this dependency is a service provider unused at compile time and can be moved to the runtime configuration
處理方式(修改版本號):
gradleLint.ignore('unused-dependency') { compileOnly group: 'org.projectlombok', name: 'lombok', version:'1.16.20' }
