Question

我是maven的新手。我使用过ant并知道如何将第三方罐子与我的罐子捆绑在一起，以便它们在运行时可用。我正在编写一个依赖于Apache tika库的应用程序。我使用依赖包括Apache Tika jar。我的jar成功生成了。我的pom.xml文件是

<groupId>com.nayan.parsers</groupId>
<artifactId>nayantikaparser</artifactId>
<version>0.0.1-1-SNAPSHOT</version>
<packaging>jar</packaging>

    </dependency>

                        </goals>
                        <configuration>

                                <artifactItem>
                                    <groupId>org.apache.tika</groupId>
                                    <artifactId>tika-app</artifactId>
                                    <version>0.7</version>
                                </artifactItem>
                            </artifactItems>
                        </configuration>
                    </execution>
                </executions>
                <configuration>
                    <testFailureIgnore>true</testFailureIgnore>
                </configuration>
            </plugin>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration>
                    <testFailureIgnore>true</testFailureIgnore>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

在运行时由于Tika不能在所有系统上使用，我想将Tika jar中的类捆绑到我的输出jar中。但我不知道该怎么做。我曾经以下列的方式做到这一点

     <zip destfile="dist/${jar.name}-${build.version}.jar">         
    <!-- Include the temporary jar -->
    <zipgroupfileset file="dist/temp.jar" />

    <zipgroupfileset file="lib/tika-app-1.3.jar"/>          
</zip>

如何使用maven做同样的事。

Answer 1

查看Maven assembly plugin。具体而言，jar-with-dependecies案例。这将确保所有依赖项都在jar中。

如果您想要更精细的控制，请查看Maven shade plugin。请参阅this case。

Answer 2

更新太迟了，但我能够达到预期的效果。我为maven使用了shade插件

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>2.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <artifactSet>
                            <excludes>
                                <exclude>org.testng</exclude>
                                <exclude>log4j</exclude>
                            </excludes>
                        </artifactSet>                          
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
