Я создаю свой java-проект, используя maven, но не смог добиться успеха. Итак, может ли кто-нибудь сказать мне основные теги и соответствующие им значения, необходимые в pom.xml для создания проекта? Кроме того, как добавить зависимости от шторма вручную из командной строки?
Моя структура каталогов проекта:
ROOT
|
|----com--->test----->newpackage---->*.class
|--- META-INF------>MANIFEST.MF
|----resource----->words.txt
|----pom.xml
|-----*.jar
Сначала я попробовал Maven Link и создал pom.xml следующим образом:
<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>
Но после этого я использую mvn package. Это исключение:

После этого я использовал эту ссылку Maven link 2 и создал pom.xml следующим образом:

На этот раз это исключение:

[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:
