如何使用maven将输出jar放入另一个文件夹？

Question

我想我的输出罐子,罐子,有依赖性的地方到另一个文件夹(不在target/,但在../libs/).

我怎样才能做到这一点？

Answer 1

为此,您可以使用maven-jar-plugin 的outputDirectory参数:

<project>
  ...
  <build>
    <plugins>
      ...
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <version>2.3.1</version>
        <configuration>
          <outputDirectory>../libs</outputDirectory>
        </configuration>
      </plugin>
      ...
    </plugins>
  </build>
  ...
</project>

但正如cdegroot写的那样,你最好不要对抗maven方式.

如果要将工件复制到项目外的目录中,解决方案可能是:

• maven-jar-plugin 并配置 outputDirectory
• maven-antrun-plugin 和复制任务
• copy-maven-plugin 作者:Evgeny Goldin

示例copy-maven-plugin是:

<plugin>
    <groupId>com.github.goldin</groupId>
    <artifactId>copy-maven-plugin</artifactId>
    <version>0.2.5</version>
    <executions>
        <execution>
            <id>deploy-to-local-directory</id>
            <phase>install</phase>
            <goals>
                <goal>copy</goal>
            </goals>
            <configuration>
                <skipIdentical>false</skipIdentical>
                <failIfNotFound>false</failIfNotFound>
                <resources>
                    <resource>
                        <description>Copy artifact to another directory</description>
                        <targetPath>/your/local/path</targetPath>
                        <directory>${project.build.directory}</directory>
                        <includes>
                            <include>*.jar</include>
                        </includes>
                    </resource>
                </resources>
            </configuration>
        </execution>
    </executions>
</plugin>

Answer 3

另一种方式是maven-resources-plugin:

<plugin>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.0.2</version>
    <executions>
        <execution>
            <id>copy-files-on-build</id>
            <phase>validate</phase>
            <goals>
                <goal>copy-resources</goal>
            </goals>
            <configuration>
                <outputDirectory>${basedir}/[TO-DIR]</outputDirectory>
                <resources>
                    <resource>
                        <directory>[FROM-DIR]</directory>
                        <!--<include>*.[MIME-TYPE]</include>-->
                        <filtering>false</filtering>
                    </resource>
                </resources>
            </configuration>
        </execution>
    </executions>
</plugin>

Answer 4

我会这样：

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-antrun-plugin</artifactId>
            <version>1.8</version>
            <executions>
                <execution>
                    <phase>install</phase>
                    <configuration>
                        <target>
                            <copy file="target/${project.artifactId}-exec.jar" tofile="../../docker/${project.artifactId}.jar"/>
                        </target>
                    </configuration>
                    <goals>
                        <goal>run</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
