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 !STACK 0 java.lang.ClassCastException: org.eclipse.core.runtime.Status cannot be cast to org.eclipse.jdt.core.IJavaModelStatus at org.eclipse.jdt.internal.core.ClassFile.getBuffer(ClassFile.java:367) at org.eclipse.jdt.internal.core.ClassFile.getSource(ClassFile.java:509) at it.unibz.instasearch.indexing.WorkspaceIndexerJDT$ClassFileSourceStorage.(WorkspaceIndexerJDT.java:425) at it.unibz.instasearch.indexing.WorkspaceIndexerJDT.indexClassFiles(WorkspaceIndexerJDT.java:193) at it.unibz.instasearch.indexing.WorkspaceIndexerJDT.indexContainers(WorkspaceIndexerJDT.java:83) at it.unibz.instasearch.indexing.WorkspaceIndexer.createIndex(WorkspaceIndexer.java:99) at it.unibz.instasearch.jobs.IndexingJob.runInWorkspace(IndexingJob.java:44) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

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

java.lang.ClassCastException: org.eclipse.core.runtime.Status cannot be cast to org.eclipse.jdt.core.IJavaModelStatus at org.eclipse.jdt.internal.core.ClassFile.getBuffer(ClassFile.java:367) at org.eclipse.jdt.internal.core.ClassFile.getSourceRange(ClassFile.java:519) at org.eclipse.jdt.internal.ui.javaeditor.EditorUtility.getEditorID(EditorUtility.java:421) at org.eclipse.jdt.internal.ui.javaeditor.EditorUtility.openInEditor(EditorUtility.java:179) at org.eclipse.jdt.ui.actions.OpenAction.run(OpenAction.java:268) at org.eclipse.jdt.ui.actions.OpenAction.run(OpenAction.java:233) at org.eclipse.jdt.ui.actions.SelectionDispatchAction.dispatchRun(SelectionDispatchAction.java:275) at org.eclipse.jdt.ui.actions.SelectionDispatchAction.run(SelectionDispatchAction.java:251) at org.eclipse.jdt.internal.ui.packageview.PackageExplorerActionGroup.handleOpen(PackageExplorerActionGroup.java:376) at org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart$4.open(PackageExplorerPart.java:538) at org.eclipse.ui.OpenAndLinkWithEditorHelper$InternalListener.open(OpenAndLinkWithEditorHelper.java:48) at org.eclipse.jface.viewers.StructuredViewer$2.run(StructuredViewer.java:853) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.ui.internal.JFaceUtil$1.run(JFaceUtil.java:50) at org.eclipse.jface.util.SafeRunnable.run(SafeRunnable.java:178) at org.eclipse.jface.viewers.StructuredViewer.fireOpen(StructuredViewer.java:850) at org.eclipse.jface.viewers.StructuredViewer.handleOpen(StructuredViewer.java:1142)

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 at org.eclipse.jdt.internal.core.ClassFile.getBuffer(ClassFile.java:367) at org.eclipse.jdt.internal.core.ClassFile.getSource(ClassFile.java:509) at it.unibz.instasearch.indexing.WorkspaceIndexerJDT$ClassFileSourceStorage.(WorkspaceIndexerJDT.java:425) at it.unibz.instasearch.indexing.WorkspaceIndexerJDT.indexClassFiles(WorkspaceIndexerJDT.java:193) at it.unibz.instasearch.indexing.WorkspaceIndexerJDT.indexContainers(WorkspaceIndexerJDT.java:83) at it.unibz.instasearch.indexing.WorkspaceIndexer.createIndex(WorkspaceIndexer.java:99) at it.unibz.instasearch.jobs.IndexingJob.runInWorkspace(IndexingJob.java:44) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

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:).

[ghost]

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 pom.xml -> [Help 1]"

[ajermakovics]

Uh, my bad. pushed a fix https://github.com/ajermakovics/eclipse-instasearch/commit/09e1517326e521486f0bc62657d1e75e7e97a8e9
