Truncated jar entries in package.xml prevent installation

[joewiz]

The maven package builds correctly and without error, but when I try to install the .xar (target/exist-expath-file-module-1.0-SNAPSHOT.xar), the Dashboard Package Manager gives me this error:

Inconsistent package descriptor, the JAR file is not in the package: ntinuations-library_2.11-1.0.1.jar

Digging into the project directory to try to find the reference to this apparently truncated filename, I found that exist-expath-file-module/target/expath-descriptors-3e387942-9387-4536-b560-05e6de31a0b9/exist.xml matched, along with several other jars whose names also appeared to be truncated:

<package xmlns="http://exist-db.org/ns/expath-pkg" xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <jar>ule-1.0-SNAPSHOT.jar</jar>
    <jar>ile-module-1.0-SNAPSHOT.jar</jar>
    <jar>m_2.11-1.3.3.jar</jar>
    <jar>ntinuations-library_2.11-1.0.1.jar</jar>
    <jar>-core_2.11-0.4.3-1.jar</jar>
    <jar>-file_2.11-0.4.3-1.jar</jar>
    <jar>brary-2.11.5.jar</jar>
    <jar>rser-combinators_2.11-1.0.2.jar</jar>
    <jar>flect-2.11.0.jar</jar>
    <jar>l_2.11-1.0.2.jar</jar>

    <jar>ore_2.11-7.1.1.jar</jar>
    <jar>ffect_2.11-7.1.0.jar</jar>
    <jar>tream_2.11-0.6a.jar</jar>
    <jar>its_2.11-1.0.4.jar</jar>
</package>

I'm afraid I don't know how to address this issue. I'm happy to try any suggestion you might have!

Below is the console output of mvn package should there be any clues.

$ mvn package

[sentheel]

Have you found any solution, i am also facing same issue.

[joewiz]

I haven't, I'm afraid. Perhaps @adamretter or @claudius108 would have some insights?

[claudius108]

Do this happens also with the latest version (0.4.9) of the kuberam-expath-plugin plugin?

[joewiz]

With a fresh checkout, I successfully built the package without error. I was even able to install the .xar file into eXist 3.3.0-DEVELOP (current head, c018bd44b). But I couldn't figure out how to call any of its functions. I tried running this and got errors about the module not being found. I even unregistered the eXist file module from conf.xml and restarted - with no change to the results below:

xquery version "3.1";

import module namespace f="http://expath.org/ns/file";

"test"

returned the following error:

Cannot compile xquery: err:XQST0059 error found while loading module f: failed to load module: 'http://expath.org/ns/file' from: 'http://expath.org/ns/file', location: 'http://expath.org/ns/file'. Source not found.

I'm happy to test, if anyone has suggestions. I've attached the .xar file here: exist-expath-file-module-1.0-SNAPSHOT.xar.zip

[adamretter]

@joewiz Okay I fixed the build and make a few updates to the XAR creation process, you should be good to go now :-)

[joewiz]

I updated to bf120f4 and tried the updated build directions in the README.md file, but running mvn clean compile package fails on this error (even after running mvn clean install on exquery/expath-file-module):

@joewiz Can you try mvn -U clean compile package?

@joewiz Doh! Sorry I had removed the repository definition in pom.xml for org.scalaz.stream:scalaz-stream_2.11:jar:0.6a. I have now added it back in. I didn't see it as I had a cached copy in my own ~/.m2.

[joewiz]

I've pulled in d64b25f and am now getting this (after re-running mvn clean install on exquery/expath-file-module):

@joewiz I am not certain but something looks corrupt on your machine, can you try removing ~/.m2/repository and trying again?

[joewiz]

@adamretter Success! This time on my home laptop with a fresh installation of maven, exquery, and expath-file-module. When I return to the other machine I'll clear the maven repository as you suggested.

Unfortunately, when I install the package, quit eXist, comment out the native file module in conf.xml, restart eXist (develop c018bd44b from today), and run the sample query above, I get the following error in exist.log:
