Installation of metadata-extractor

I'm stuck on installation.
I downloaded Maven, but I'm not sure which file within
the metadata-extractor folder (that I downloaded from the repo) to use as the target.
I tried all the files at the top level.
All attempts have failed, e.g.
java -jar metadata-extractor-2.13.0.jar build.gradle
com.drew.imaging.ImageProcessingException: File format could not be determined
I am using v2.13.0 of the meta-data extractor

I've just started to code and took interest in this project but also had issues using it. Instead of using Maven i just downloaded the source code from github and threw the 'com' folder into my myproject/src folder. Then i downloaded the xmpcore-6.1.10.jar library and added it to the Build Path. Got it working that way. I hope someone will give you a better solution but if you just wanna do something right away, you can try this solution.

Try downloading IntelliJ and create a "new project from version controll". Use the URL given on the GitHub page (under download/code). That will save you a lot of problems.

SUMO SRTM osmosis plugin

I have been trying to run the SRTM-osmosis plugin (https://github.com/locked-fg/osmosis-srtm-plugin) for quite some time now. In the wiki, it is mentioned that you should move the compiled jar to the directory (/~.openstreetmaps/osmosis/plugins). I can't find the .jar file and don't know to generate it as mentioned in the wiki ?
Anyone faced a similar problem with the SRTM plugin ?!

The documentation was updated (https://github.com/locked-fg/osmosis-srtm-plugin). Just copied the .jar file to (~/.openstreetmaps/osmosis/plugins) and used the command: osmosis --read-xml map.osm --write-srtm tagName=ele --write-xml map_with_srtm.osm

STS project gives error cannot be read or is not a valid ZIP file

I am for the first time trying java in Spring Tool Suite and using an example project imported, now running into endless issues. I tried building the project and go the following error:
Archive for required library: 'C:/Users/cccc/.m2/repository/com/vaadin/vaadin-client/7.1.0/
vaadin-client-7.1.0.jar' in project 'quicktickets-dashboard' cannot be read or is not a
valid ZIP file quicktickets-dashboard Build path Build Path Problem
This is probably a spring issue and not related to the project itself. Please does anyone have a working solution to this. Tried a few, building, closing, rebuilding, deleting local repository etc. but still the same issue. Any ideas appreciated.

The most likely explanation is that your maven cache is corrupted. First, check if the C:/Users/cccc/.m2/repository/com/vaadin/vaadin-client/7.1.0/vaadin-client-7.1.0.jar jar is complete. Run jar tvf on the file to make sure you can use it.
If you're lucky, things will work if you delete the C:/Users/cccc/.m2/repository/com/vaadin/vaadin-client/7.1.0/ folder, but if that doesn't work, you will have to try deleting C:/Users/cccc/.m2/repository. It's just a local cache of artifacts downloaded from maven central or an internal repository, so it is OK to delete.
I am 90% certain this would fix your problem.

I clear /.m2/repository/.cache and it works fine.

selenium-server-standalone-2.37.0.jar is broken?

I'm trying to use the library "selenium-server-standalone-2.37.0.jar" in a project. The project was previously using "selenium-server-standalone-2.24.1.jar", but I think that is too out of date for my current version of Chrome.
When I tried to switch out the old jar for the new jar, though, I started getting the Eclipse error:
Description Resource Path Location Type
Archive for required library: 'mypath/lib/selenium-server-standalone-2.37.0.jar' in project 'BookProject' cannot be read or is not a valid ZIP file BookProject Build path Build Path Problem
So I tried unpacking the jar with 7-zip, but in there I got the error:
Can not open file 'mypath/selenium-server-standalone-2.37.0.jar' as archive
Is this jar actually broken, or is there something I'm missing here? If this one isn't working, does anyone know where I could find the previous version? I couldn't find that anywhere.

If you are unable to open the jar even using 7-zip, then it's corrupt.
I'd recommend re-downloading it. Furthermore, when using eclipse, it might be a good idea to clear your dependency cache when upgrading things.. that usually solves things.
Edit
I suppose that it could be possible that the jar itself is just corrupt. If that's the case, try going to https://code.google.com/p/selenium/downloads/list and where it says "Search: Current Downloads" Select "Deprecated Downloads"
I still use
https://code.google.com/p/selenium/downloads/detail?name=selenium-server-standalone-2.35.0.jar

commons-logging-1.1.jar; cannot read zip file entry

I have imported a GWT project from GIT , but when i run maven Install
it says
.m2\repository\commons-logging\commons-logging\1.1\commons-logging-1.1.jar; cannot read zip file entry
and if i simply run my application , i get this
\git\my-Search-Engine\qsse\war}: java.lang.NoClassDefFoundError: com/google/inject/servlet/GuiceServletContextListener
I tried to find out the way , one solution i found was to move the guice-servlet-3.0 from build path to \qsse\war\webinf\lib
but if i do that i start getting this exception
ava.lang.NoClassDefFoundError: com/google/inject/Injector
any idea how can i resolve this

For first question:
Can you open it in a WinZip or other compression tool.
Try deleting that jar and build again. Let Maven download it a fresh.
For Second Questin:
Which GWT version are you using ?
Verify that the required JAR is in your classpath including guice.jar and guice-servlet-3.0.jar
And also, guice-servlet-3.0.jar should not be in you launch configuration classpath. It has to be in your project classpath.

For the second question, can you also move the other guice jars to webinf\lib ? (guice-3.0.jar should be missing)
