从JDK8升级到JDK11，看这篇就足够了

gradle升级7.1版本概要

1. apply from, url须是安全访问，有两种方式修改

  1. a. http --> https
  2. b. apply from: resources.text.fromInsecureUri("http://www.deepdraw.cn/internal/prelude.gradle")

2 . 本地运行，init.gradle修改如下：

  1. a. 阿里云仓库安全访问
  2. ext.ALIYUN_REPO_URL = 'http://maven.aliyun.com/nexus/content/groups/public/'
  3. 修改后:
  4. ext.ALIYUN_REPO_URL = 'https://maven.aliyun.com/nexus/content/groups/public/'
  6. b. 深绘仓库安全访问
  7. maven {
  8.     url DEEPDRAW_REPO_URL
  9.     credentials {
  10.         username DEEPDRAW_REPO_ACCOUNT
  11.         password DEEPDRAW_REPO_PWD
  12.     }
  13. }
  15. 修改后:
  17. maven {
  18.     allowInsecureProtocol = true
  19.     url DEEPDRAW_REPO_URL
  20.     credentials {
  21.         username DEEPDRAW_REPO_ACCOUNT
  22.         password DEEPDRAW_REPO_PWD
  23.     }
  24. }

3. 外部引用jar包与gradle引用冲突

打包时WEB-INF/libs中依赖模块名与gradle引入依赖冲突,提示Entry duplicate, 目前解决方案为删除libs中的外部依赖统一由gradle引入:

  1. 冲突模块:
  2. a. ognl-3.0.6
  3. b. commons-lang-2.6

4. testCompile -> testImplementation

  1. testCompile group: 'junit', name: 'junit', version: '4.12'
  2. 修改后:
  3. testImplementation 'junit:junit:4.12'

5. plugins中插件版本过低无法引入

  1. a. 更新插件版本
  2. b. 外部引入插件jar包，并在buildscript中声明
  3. buildscript {
  4.   ...
  5.   dependencies {
  6.     classpath files("libs/gradle-js-plugin-2.14.1.jar")
  7.   }
  8. }
  9. c. 寻找替代插件

6. compile -> implementation

  1. compile已废弃,替换为implementation
  1. compile group: 'mysql', name: 'mysql-connector-java', version: '5.1.25'
  2. 修改后:
  3. implementation 'mysql:mysql-connector-java:5.1.25'

7. ant编译

  1. compile, runtime等已经废弃过时
  2. compile -> compileClasspath, runtime -> runtimeClasspath
  4. 如: classpath: configurations.compile.asPath)
  5. 修改后: classpath: configurations.compileClasspath.asPath)

8. testCompile配置问题

testImplementation引入后需要显式配置testCompile,否则无法找到测试类

  1. configurations {
  2.     testCompile
  3. }

模块化项目只需要在subprojects中添加该配置即可

9. 过时配置或参数解决，编译参数添加”—warning-mode all”找到过时参数然后更新

10 . 对于推送jar包项目uploadArchives废弃的处理

  1. apply plugin: 'maven-publish'
  3. publishing {
  4.     publications {
  5.         maven(MavenPublication) {
  6.             groupId = 'cn.deepdraw'
  7.             artifactId = 'product-import-api'
  8.             version = version
  10.         }
  11.     }
  12.     repositories {
  13.         maven {
  14.             allowInsecureProtocol = true
  15.             url DEEPDRAW_REPO_URL
  16.             credentials {
  17.                 username DEEPDRAW_REPO_ACCOUNT
  18.                 password DEEPDRAW_REPO_PWD
  19.             }
  20.         }
  21.     }
  22. }

11. 生成本地Pom文件

Maven Publish Plugin#Tasks
— generatePomFileForPubNamePublication
— GenerateMavenPom

  1. task writePom {
  2.     pom {}.writeTo(pomPath)
  3. }

修改为

  1. task writePom {
  2.     model {
  3.         tasks.generatePomFileForMavenPublication {
  4.             destination = file(pomPath)
  5.         }
  6.     }
  7. }

12. JacocoReportBase

classDirectories为只读
使用getClassDirectories().setFrom()代替

jdk11升级总结

build.gradle

  • 增加依赖(取决于服务会不会用到)
  1. compile('javax.xml.bind:jaxb-api:2.3.1')
  2. compile('org.glassfish.jaxb:jaxb-core:2.3.0.1')
  3. compile('org.javassist:javassist:3.27.0-GA')
  • 所有jdk 1.8改为11

Dockfile

  • 修改tomcat
  1. registry.cn-hangzhou.aliyuncs.com/deepdraw-base/tomcat9-jdk11

Jenkinsfile

  • 修改jdk
  1.     tools {
  2.         jdk 'jdk11'
  3.     }

遇到的问题

  • 无法读取dubbo中方法(ClassDefNotFound)

原因：二进制文件无法被读取

解决方案：增加依赖compile(‘org.javassist:javassist:3.27.0-GA’)
