Gradle 转 Maven 小记(ReportPortal为例)

发表于 更新于 分类于

公司访问外网要代理, 证书也替换了, gradle不能忽略证书验证, 替换证书未果, 遂起了转化maven工程的念头

创建pom.xml

在build.gradle文件中加入以下内容

1
2
3
4
5
apply plugin: 'maven'
task createPom << {
    pom {
    }.writeTo("pom.xml")
}

在项目根目录调用命令gradle createPom

新增仓库

在build.gradle中是这样定义的

1
2
3
4
5
6
7
8
9
10

repositories {
    mavenCentral()
    mavenLocal()
    maven { url "http://dl.bintray.com/epam/reportportal" }
    maven { url "http://jasperreports.sourceforge.net/maven2" }
    maven { url "http://jaspersoft.artifactoryonline.com/jaspersoft/third-party-ce-artifacts" }
    maven { url "https://dl.bintray.com/michaelklishin/maven/" }

    if (!releaseMode) {
        maven { url 'https://jitpack.io' }
    }
}

改写pom对应应该如下写法:

1
2
3
4
5
6
<repositories>  
  <repository>
    <id>epam</id>  
    <url>http://dl.bintray.com/epam/reportportal</url>  
  </repository>
</repositories>

补全dependency

在build.gradle中dependencyManagement是如下写法:

1
2
3
4
5
6
dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-starter-parent:Edgware.SR3"
        mavenBom "org.springframework.boot:spring-boot-dependencies:1.5.9.RELEASE"
    }
}

改写pom应为如下写法:

1
2
3
4
5

7
8
9
10

12
13

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>1.5.9.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Dalston.SR1</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

应该在一些插件和其他设置中还隐含了一些依赖, 导致mvn install时还有一些依赖没有找到, 逐个手动加上. 建议google搜索maven 类名

springboot no manifest

在pom中加入:

        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
        </execution>
    </executions>
</plugin>
