Maven - 为Java项目中的每个Java包创建一个jar

发布于 2020-03-27 15:38:14

可以说我有3个软件包,并且需要为每个仅包含当前软件包内容的软件包创建一个jar。我的尝试是:

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <version>2.4</version>
                <executions>
                    <execution>
                        <id>first-jar</id>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                        <configuration>
                            <classifier>first-jar</classifier>
                            <excludes>
                                <exclude>/maven.task.3/src/main/java/third/ThirdMain.java
                                </exclude>
                                <exclude>/maven.task.3/src/main/java/second/SecondMain.java
                                </exclude>
                            </excludes>
                        </configuration>
                    </execution>
                    <execution>
                        <id>second-jar</id>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                        <configuration>
                            <classifier>second-jar</classifier>
                            <excludes>
                                <exclude>/maven.task.3/src/main/java/first/FirstMain.java
                                </exclude>
                                <exclude>/maven.task.3/src/main/java/third/ThirdMain.java
                                </exclude>
                            </excludes>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

这确实会创建不同的jar,但是其中的内容是相同的,这意味着exclude子句不起作用。我尝试仅排除类(相对/绝对路径)和仅包。不要问为什么我要这样做是为了做作业,这没有什么意义!这是我尝试执行的方式,如果还有其他更有效的方式,请随时与我分享!

编辑:不得使用模块化结构,它必须是一个单独的项目。

评论中已经回答了这个问题,但这是一个示例。

父pom:

<?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>

  <groupId>com.essexboy</groupId>
  <artifactId>parent</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>pom</packaging>

  <modules>
    <module>jar1</module>
    <module>jar2</module>
  </modules>

</project>

还有2个子/模块poms,只有artifactId不同:

<?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>
    <artifactId>parent</artifactId>
    <groupId>com.essexboy</groupId>
    <version>1.0-SNAPSHOT</version>
  </parent>

  <artifactId>jar1</artifactId>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>
  </dependencies>

  <build>
  </build>
</project>

额外信息

我使用以下命令创建了父项:

mvn archetype:generate -DarchetypeGroupId=org.codehaus.mojo.archetypes -DarchetypeArtifactId=pom-root -DarchetypeVersion=RELEASE

然后使用命令创建2个模块

mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=RELEASE

如果您必须有一个jar项目(没有模块和父项目),则可以使用shade-plugin进行操作

<?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>

    <groupId>com.essexboy</groupId>

    <version>1.0-SNAPSHOT</version>
