Hello,
I am working with RSE to edit Java code remotely. Most of my remote projects use Maven as the build tool.
The problem is that Eclipse cannot find any of the dependencies, as the Maven plugin doesn't seem to play nice with RSE.
The .project file created by RSE has basically nothing in it.
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>ppa-jeremym-l.slac.stanford.edu_hps-java</name>
<comment></comment>
<projects>
</projects>
<buildSpec>
</buildSpec>
<natures>
</natures>
</projectDescription>
And, by default, it doesn't make any .classpath file at all.
So is there a way to specify/import these Maven dependencies somehow?
When I attempt to activate Maven under "Configure" I get a rather cryptic "NullPointerException", and then nothing seems to work. I'm assuming this is because the Maven plugin and most of the rest of Eclipse are designed to work with local file systems and so probably can't even find my pom file.
Can anyone lay out my options for getting these dependencies into the remote project? I'm fine with executing external commands, but I don't think specifying all the dependencies manually in the project menu is going to work, as there are too many, unless it can somehow be done automatically. Project dependencies have the same down side. The projects I need to build have a really complex dependency tree, so I can't just link to a couple other projects and be done with it.
Right now, Eclipse does not even find the Java system libraries that ship with the JRE, e.g. says packages like "java.util" cannot be found, even when I manually add javanature to the .project file. So something seems off there.
Would I be able to use 'mvn eclipse:eclipse' to get this working? So far that doesn't seem to do it.
I just started playing with this, so perhaps I'm missing something obvious. The RSE documentation doesn't seem to be much help though, as I can't find any mention of specifying Java dependencies and the like.
Thanks for any advice or tips you can give me on this issue.

When you use RSE to edit a remote file, a cached version of the file gets
stored in the RemoteSystemTempFiles project (the project is filtered out of
the Project Explorer view but you can see it by changing the view filters).
When you say you add a java nature to the .project file, are you saying you
added the nature to the RemoteSystemTempFiles project?

Hi, William.
I never did figure out a resolution to this problem. When using RSE, I typically have a terminal open and run 'mvn' manually to do the builds from the project's directory on the remote host. In other words, I bypass the Eclipse Maven plugin entirely, as it seems to only work correctly with local projects. I do not even enable Maven nature on the project, as it will then just constantly cause errors to pop up when it tries to update or build.
I corresponded a bit with the maintainers of RSE about this issue, and I was told that doing dependency management is not part of the scope of that project.
I think the problem here is that the Maven plugin, or all Eclipse plugins for that matter, does not see files in an RSE project like it does local ones. I realize this is vague. I don't have a great understanding of the internals here. The capability for doing dependency management is probably something that would need to be added to the part of RSE which manages remote projects. I don't think it has anything like this capability right now.
Perhaps there is something that can be done to work around this using the 'RemoteSystemTempFiles' project, as referenced in some of the replies here. I never investigated this.

Thank you so much for getting back to me and although I'm sad to hear it, you are at least saving me from stumbling down the same path.
I really never criticize an OSS project, but I'm so disappointed that this isn't an aim of RSE. If tooling the remote system to build from a "client Eclipse" using something as general as maven isn't an aim of the project, I'm really not clear what RSE is going for.
Sorry for the whinging, but if Eclipse was able to simply attach to build servers, a litany of problems around configuration management, continuous integration, cross-compilation, compilation time, etc. could be solved in one fell swoop. And once you have the deep access that RSE advertises, it seems like that should be possible.
Thanks anyway,
-Will
