Maven deploy snapshot with scp throws NoSuchElementException
提问by Simon Urli
I want to be able to deploy a snapshot of a maven project on a nexus repository using scp. Here's the current configuration of my pom.xml for interesting parts:
我希望能够使用 scp 在 nexus 存储库上部署 Maven 项目的快照。这是我 pom.xml 中有趣部分的当前配置：
<distributionManagement>
<snapshotRepository>
<id>gforge.inria.fr-snapshot</id>
<name>inria-snapshots</name>
<url>scp://scm.gforge.inria.fr/home/groups/spoon/htdocs/repositories/snapshots</url>
</snapshotRepository>
<site>
<id>gforge.inria.fr-site</id>
<name>inria</name>
<url>scp://scm.gforge.inria.fr/home/groups/spoon/htdocs/mvnsites/spoon-core</url>
</site>
</distributionManagement>
[...]
<extensions>
<extension>
<groupId>org.apache.maven.wagon</groupId>
<artifactId>wagon-ssh</artifactId>
</extension>
</extensions>
</build>
The entire pom.xml is available there.
整个 pom.xml 在那里可用。
We are using pair of keys to authenticate to our repository, so I enter the following in ~/.m2/settings.xml:
我们使用一对密钥对我们的存储库进行身份验证，因此我在中输入以下内容~/.m2/settings.xml：
<server>
<id>gforge.inria.fr-snapshot</id>
<username>XXXX</username>
<privateKey>/path/to/the/private/key</privateKey>
</server>
And when I launch the mvn clean deployI obtain the following error:
当我启动时，mvn clean deploy我收到以下错误：
[ERROR] Failed to execute goal org.sonatype.plugins:nexus-staging-maven-plugin:1.6.2:deploy (injected-nexus-deploy) on project spoon-core: Failed to deploy artifacts/metadata: Cannot access scp://scm.gforge.inria.fr/home/groups/spoon/htdocs/repositories/snapshots with type default using the available connector factories: BasicRepositoryConnectorFactory: Cannot access scp://scm.gforge.inria.fr/home/groups/spoon/htdocs/repositories/snapshots using the registered transporter factories: WagonTransporterFactory: java.util.NoSuchElementException

For information, I'm using Maven 3.3.9, and Java 8 (I tested with openjdk and oracle JDK, with the same result).
有关信息，我使用的是 Maven 3.3.9 和 Java 8（我使用 openjdk 和 oracle JDK 进行了测试，结果相同）。
I know my pom.xml setup should work: it worked for months on a virtual machine. Sadly I did not setup that VM and we lost it recently without any backup. I don't have any information on the java or maven version it was on this machine.
我知道我的 pom.xml 设置应该可以工作：它在虚拟机上工作了几个月。遗憾的是我没有设置那个虚拟机，我们最近在没有任何备份的情况下丢失了它。我没有关于这台机器上的 java 或 maven 版本的任何信息。
This VM was used through a jenkins Job to do mvn deployperiodically and you could have a look on the different logs of this job there: https://ci.inria.fr/sos/job/Spoon-Snapshot-Deployer/. Before July the 28th it worked well, the logs showing my error are since August the 2nd.
该 VM 通过 jenkins 作业mvn deploy定期执行，您可以在此处查看此作业的不同日志：https: //ci.inria.fr/sos/job/Spoon-Snapshot-Deployer/ 。在 7 月 28 日之前它运行良好，显示我的错误的日志是从 8 月 2 日开始的。

Following your pom, error come from the wagon-sshextension, used by the nexus-staging-maven-plugin.
在您的 pom 之后，错误来自wagon-ssh扩展名，由nexus-staging-maven-plugin.
As you don't know what could be versions used by your crashed VM, did you try by just updating the wagon-sshversion associated to the nexus-staging-maven-plugin? For example, by using:
由于您不知道崩溃的 VM 可能使用哪些版本，您是否尝试通过更新wagon-ssh与nexus-staging-maven-plugin? 例如，通过使用：
<plugin>
<groupId>org.sonatype.plugins</groupId>
<artifactId>nexus-staging-maven-plugin</artifactId>
<version>1.6.2</version>
<extensions>true</extensions>
<configuration>
<serverId>ossrh</serverId>
<nexusUrl>https://oss.sonatype.org/</nexusUrl>
<autoReleaseAfterClose>true</autoReleaseAfterClose>
</configuration>
<dependencies>
<dependency>
<groupId>org.apache.maven.wagon</groupId>
<artifactId>wagon-ssh</artifactId>
<version>2.12</version>
</dependency>

</plugin>
