Another Error creating index

[ghost]

Tried to index a project which only had Maven dependencies (with source download enabled)

Instasearch indexing, worked for a while indexing the maven dependency jars, then stopped.

I'm using STS version:
Version: 3.6.4.RELEASE
Build Id: 201503100339
Platform: Eclipse Luna SR1 (4.4.2)

JAVA version: Oracle windows 64 jdk1.7.0_25

The plugin log file had:

[ajermakovics]

what's strange is that the exception comes from Eclipse's classes.
does re-indexing the workspace help at all?

Hi,

I tried again with the latest STS
Version: 3.6.4.RELEASE
Build Id: 201503100339
Platform: Eclipse Luna SR1 (4.4.2)

JAVA: ORacle 1.7.79 64bit

new workspace

instasearch:

after clicking on instsearch build index, I can see it working through the maven dependencies in the project. And this it stops.

I wonder if this jar is the issue?
http://grepcode.com/snapshot/repo1.maven.org/maven2/com.wordnik/swagger-core_2.9.1/1.2.0

For swagger-core_2.9.1-1.2.0.jar the swagger-core_2.9.1-1.2.0-sources.jar does not contain sources for all classes in the jar???

the workspace .log shows this:
!ENTRY it.unibz.instasearch 4 0 2015-05-21 09:31:21.360
!MESSAGE org.eclipse.core.runtime.Status cannot be cast to org.eclipse.jdt.core.IJavaModelStatus

So, if I hack the pom and add an exclusion for swagger-core_2.9.1, the indexing gets further.

Next problematic jar is http://grepcode.com/snapshot/repo1.maven.org/maven2/org.parboiled/parboiled-scala_2.10/1.1.6

interesting enough, when I use STS to look at the source of org.parboiled.scala.package.class
STS shows and error dialog: "An error has occurred. See error log for more details.
org.eclipse.core.runtime.Status cannot be cast to org.eclipse.jdt.core.IJavaModelStatus"

the log file has a familiar classcastexecption

Any chance the plugin could be altered to avoid this stacktrace:

java.lang.ClassCastException: org.eclipse.core.runtime.Status cannot be cast to org.eclipse.jdt.core.IJavaModelStatus

Perhaps a try/catch around
WorkspaceIndexerJDT.indexClassFiles(WorkspaceIndexerJDT.java:193)

I can't seem to build the plugin myself due to this error
"[ERROR] Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:0.19.0:validate-version (default-validate-version) on project it.unibz.instasearch: OSGi version 1.5.6 in META-INF/MANIFEST.MF does not match Maven version 1.5.7 in
pom.xml -> [Help 1]"

[ajermakovics]

Probably putting these lines in try-catch block:
https://github.com/ajermakovics/eclipse-instasearch/blob/master/instasearch/src/it/unibz/instasearch/indexing/WorkspaceIndexerJDT.java#L193-L196

would skip the files in error. Building InstaSearch from source is easy with Maven if you're up for a little challange:).

Sure, happy to submit a fix.

I am having an issue building with maven at the mo:
any suggestions?

"[ERROR] Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:0.19.0:validate-version (default-validate-version) on project it.unibz.instasearch: OSGi version 1.5.6 in META-INF/MANIFEST.MF does not match Maven version 1.5.7 in

[ajermakovics]

Uh, my bad. pushed a fix 09e1517
