我已经从netbeans上现有的maven项目中创建了一个可运行的jar文件，它包含pom.xml中包含的所有依赖项
当我在Netbeans上运行它时，它可以工作：

stampa
adsa
stampa2

字符串
当我从可运行的jar文件中运行它时，我得到了这个错误：
java -jar ./Prova-1.0-SNAPSHOT-jar-with-dependencies.jar

stampa
adsa    

Exception in thread "main" javax.jcr.RepositoryException: Unable to access a repository with the following settings:

        org.apache.jackrabbit.repository.uri: http://localhost:8082/server

    The following RepositoryFactory classes were consulted:

        org.apache.jackrabbit.core.RepositoryFactoryImpl: declined

    Perhaps the repository you are trying to access is not available at the moment.

        at org.apache.jackrabbit.commons.JcrUtils.getRepository(JcrUtils.java:223)
        at org.apache.jackrabbit.commons.JcrUtils.getRepository(JcrUtils.java:263)
        at com.mycompany.leggitutto.Source.main(Source.java:38)

型
我不明白
为什么在netbeans上不抛出RepositoryException？
Java代码是一样的，构建成功，运行是不同的！

public static void main(String[] args) throws Exception 
{

    System.out.println("stampa");
    System.out.println("adsa");

    Repository repository1 = JcrUtils.getRepository("http://localhost:8082/server"); 
    Session session1 = repository1.login(new SimpleCredentials("admin","admin".toCharArray()), "default");

    System.out.println("stampa2");
}

型
Jackrabbit服务器运行在
第一个月
我甚至在firefox上检查过，仓库是可以访问的。
如果有人能帮我解决这个问题，我会很高兴：）

问题是org.apache.jackrabbit:jackrabbit-jcr-commons和org.apache.jackrabbit:jackrabbit-jcr2dav有相同的文件META-INF/services/javax.jcr.RepositoryFactory，其中包含工厂，正确的是org.apache.jackrabbit.jcr2dav.Jcr2davRepositoryFactory。
下面，这个文件是使用shade插件从jackrabbit-jcr-commons中删除的，以避免与jackrabbit-jcr 2dav冲突。

  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-shade-plugin</artifactId>
  <version>3.5.1</version>

我解决了，
我在onejar-maven-plugin中更改了pom.xml中的maven插件，它现在可以工作了。
显然，使用maven-shade-plugin或maven-assembly-plugin，并不是每个依赖项都被添加到最终的jar“可执行文件”中。
This pom.xml is working耶!！

<build>
    <plugins>

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>

            <source>1.8</source>
            <target>1.8</target>
        </configuration>

    </plugin> 

    <plugin>
        <groupId>org.dstovall</groupId>
        <artifactId>onejar-maven-plugin</artifactId>

        <executions>
            <execution>
                <configuration>
                    <mainClass>Valid.Main.Class</mainClass>
                    <!-- Optional -->
                    <onejarVersion>0.97</onejarVersion>
                    <!-- Optional, default is false -->
                    <attachToBuild>true</attachToBuild>
                    <!-- Optional, default is "onejar" -->

                </goals>
            </execution>
        </executions>
