如何docker构建带有模块的maven项目？

问题描述 投票：0回答：1

我有一个带有模块的 Maven 项目，我的目的是为一个模块提供一个 docker 文件。所以我所做的是：

我的模块的 pom.xml 

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>pt.com.daniel</groupId>
        <artifactId>kafka-example</artifactId>
        <version>1.0-SNAPSHOT</version>
        <relativePath>../pom.xml</relativePath>
    </parent>

    <artifactId>producer</artifactId>

    <properties>
        <maven.compiler.source>22</maven.compiler.source>
        <maven.compiler.target>22</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

</project>

父级的 pom.xml 

<project xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

</project>

模块根目录下的 Docker 文件

FROM openjdk:22
LABEL authors="daniel castro"

ARG MAVEN_VERSION=3.9.6

# Adjusting the module's pom.xml to reference the new parent-pom.xml
RUN sed -i 's/<relativePath>..\/pom.xml<\/relativePath>/<relativePath>.\/parent-pom.xml<\/relativePath>/' /usr/src/myapp/pom.xml

RUN mvn clean install
# Refer to Maven build -> finalName
ARG JAR_FILE=target/producer-1.0-SNAPSHOT.jar.original

# cp target/spring-boot-web.jar /opt/app/app.jar
RUN cp ${JAR_FILE} /usr/src/myapp/app.jar

# java -jar /opt/app/app.jar
ENTRYPOINT ["java","-jar","app.jar"]

当我执行

C:\Users\dfcas\IdeaProjects\kafka-example\producer>docker build -t producer:1.0 .

时

我正在模块的文件夹中运行。

我收到错误，但我可以检查我的 docker 桌面日志

如上所述，sed 命令生成我的模块的 pom.xml 为

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>pt.com.daniel</groupId>
<artifactId>kafka-example</artifactId>
<version>1.0-SNAPSHOT</version>
<relativePath>./parent-pom.xml</relativePath>
</parent>
<artifactId>producer</artifactId>
<properties>
<maven.compiler.source>22</maven.compiler.source>
<maven.compiler.target>22</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
</project>

这是因为命令 COPY ../pom.xml /usr/src/myapp/parent-pom.xml 正在复制模块 pom.xml 而不是像应该做的那样复制父模块。如何解决这个问题？

docker

我找到了解决方法

我在 pom.xml 上添加了一个插件，将其自身复制到每个模块并重命名。这发生在 docker 构建之前
