使用 maven 将 java 代码和依赖项合并到一个 jar（可执行 jar）中

Question

我正在尝试使用 Netbeans 将我的 src 编译成一个 jar 文件。我目前通过右键单击 Build with Dependecies 进行编译。这是我的 pom 文件

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

当我执行输出 jar 文件时，它找不到 com.github.scribejava 和 com.drewnoakes 库。此外，如果我不使用 maven-jar-plugin，则主 class 不会添加到 meta-inf/manifest.mf。我到底做错了什么？

Answer 1

将执行标签放在 maven-assembly-plugin 的配置标签之外，如下所示：

<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-assembly-plugin</artifactId> <version>2.6</version> <configuration> <archive> <manifest> <mainClass>ca.osmcanada.osvuploadr.JFMain</mainClass> </manifest> </archive> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin>
