Eclipse Marketplace Download URL returns 404 #16

Closed scoth closed 7 years ago

scoth commented 7 years ago

The eclipse market place has the spark builder generator listed as a plugin to install. However when it tries to download the plugin the following URL returns a 404:

https://helospark.com/eclipse_plugin/SparkBuilderGeneratorPlugin/content.xml

Is it possible to bring up this plugin on the server again, and/or provide a different means to download the plugin. ( Could you host it on github? ). I suppose I could build it myself, but I am not that familiar with building eclipse plugins.

Apologies if this is type of issue is inappropriate, I am not aware of another means of contacting the plugin maintainer.

Hi Scoth,

The generated update site contains jar for the context file and it is still available: https://helospark.com/eclipse_plugin/SparkBuilderGeneratorPlugin/content.jar

In the logs I cannot see many queries for context.xml, as far as I know Eclipse tries context.xml if it cannot find content.jar.

I guess I can unzip the jar content and make XMLs available too, but it shouldn't be necessary. Which Eclipse version do you use? Also it is possible to download via (old) FTP if HTTPS is not available for any reason, just go to help->Install new software and copy this URI: ftp://helospark.com/eclipse_plugin/SparkBuilderGeneratorPlugin/

I am using the new Oxygen (4.7) version of Eclipse. I tried the ftp url and I get the following:

Very unusual. Based on some Google search it seems like a common problem, caused by the jar file somehow (?) gets corrupted: https://stackoverflow.com/questions/25094583/error-when-try-install-plugin Seems like some manual deleting of jar/xml files could solve it.

Some other thoughs:

I was able to install the unsigned eclipse decompiler from the marketplace. So unsigned content of some kind works.

When I try to open it as a zipfile I get the following error:

unzip -l /home/shale/opt/eclipse-jee-oxygen-R-linux-gtk-x86_64/plugins/com.helospark.SparkBuilderGenerator_0.0.10.201704081131.jar Archive: /home/shale/opt/eclipse-jee-oxygen-R-linux-gtk-x86_64/plugins/com.helospark.SparkBuilderGenerator_0.0.10.201704081131.jar End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of /home/shale/opt/eclipse-jee-oxygen-R-linux-gtk-x86_64/plugins/com.helospark.SparkBuilderGenerator_0.0.10.201704081131.jar or /home/shale/opt/eclipse-jee-oxygen-R-linux-gtk-x86_64/plugins/com.helospark.SparkBuilderGenerator_0.0.10.201704081131.jar.zip, and cannot find /home/shale/opt/eclipse-jee-oxygen-R-linux-gtk-x86_64/plugins/com.helospark.SparkBuilderGenerator_0.0.10.201704081131.jar.ZIP, period.

This is the error I get from the marketplace. You pointed out that it could download the .jar. I wonder if it is trying to get the content.xml first?:

Unable to read repository at https://helospark.com/eclipse_plugin/SparkBuilderGeneratorPlugin/content.xml. sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Based on the exception about the marketplace download failure most likely it is caused by: http://gnuarmeclipse.github.io/blog/2016/12/02/plugins-install-issue/ I'm using certificate from Let's Encrypt which was added to the Java certificate store in version 1.8.101, but it should be able to check the validity of the certificate with older Java versions, but seems like it was blocked by a firewall. I'm not entirely sure what was blocked without analyzing the traffic.

"I wonder if it is trying to get the content.xml first?" In this case Eclipse does not do a single request to my server, but fail fast after checking the certificate and unable to verify it.

About the downloaded jar file, have you tried the suggested solution on StackOverflow? It really seems like it got corrupted.

Hey Scoth!

Any update on this?

scoth commented 7 years ago

I was able to update my JDK just now. I was running jdk1.8.0_60, and updating to jdk1.8.0_131 allowed me to install the plugin without problems. Thanks for your help!
