我正在使用 maven 构建我的 java 项目，但没有成功。那么，谁能告诉我 pom.xml 中构建项目所需的基本标签及其对应的值？另外，如何从命令行手动添加风暴依赖项？
我的项目目录结构：
ROOT
|
|----com--->test----->newpackage---->*.class
|--- META-INF------>MANIFEST.MF
|----resource----->words.txt
|----pom.xml
|-----*.jar
最初我尝试了Maven Link并创建了pom.xml这样的：
<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">
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<phase>com.test.newpackage</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
但是，在那之后我使用mvn package. 它抛出这个异常：
[INFO] Scanning for projects...

之后，我使用了这个链接Maven 链接 2并像这样创建了 pom.xml：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</build>
<repositories>

<dependencies>
<!-- Storm Dependency -->
<dependency>
<groupId>storm</groupId>
<artifactId>storm</artifactId>
<version>0.8.1</version>
</dependency>
</dependencies>
</project>
这次它抛出了这个异常：
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Failed to resolve artifact.
Missing:
----------
1) storm:storm:jar:0.8.1
Try downloading the file manually from the project website.
Then, install it using the command:
mvn install:install-file -DgroupId=storm -DartifactId=storm -Dversion=0.8.1 -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=storm -DartifactId=storm -Dversion=0.8.1 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]
Path to dependency:
1) com.test.newpackage:wordcount:jar:0.0.1
2) storm:storm:jar:0.8.1
----------
1 required artifact is missing.
for artifact:
com.test.newpackage:wordcount:jar:0.0.1
