I’m testing the [OpenWire Plugin (Click to GIT Repo)](https://github.com/exabrial/graylog-plugin-openwire).

The plugin Works as intended on Graylog 2.4.7, but our production server runs 2.3.2 . In the production server we get this errors:

`2019-08-12T17:25:46.162-03:00 ERROR [Version] Unable to read com.github.exabrial.graylog-plugin-openwire/graylog-plugin.properties, this build has no version number. com.github.zafarkhaja.semver.UnexpectedCharacterException: null at com.github.zafarkhaja.semver.VersionParser.consumeNextCharacter(VersionParser.java:516) ~[graylog.jar:?] at com.github.zafarkhaja.semver.VersionParser.digits(VersionParser.java:448) ~[graylog.jar:?] at com.github.zafarkhaja.semver.VersionParser.numericIdentifier(VersionParser.java:408) ~[graylog.jar:?] at com.github.zafarkhaja.semver.VersionParser.parseVersionCore(VersionParser.java:285) ~[graylog.jar:?] at com.github.zafarkhaja.semver.VersionParser.parseValidSemVer(VersionParser.java:255) ~[graylog.jar:?] at com.github.zafarkhaja.semver.VersionParser.parseValidSemVer(VersionParser.java:195) ~[graylog.jar:?] at com.github.zafarkhaja.semver.Version.valueOf(Version.java:265) ~[graylog.jar:?] at org.graylog2.plugin.Version.fromClasspathProperties(Version.java:219) [graylog.jar:?] at org.graylog2.plugin.Version.fromPluginProperties(Version.java:163) [graylog.jar:?] at com.github.exabrial.graylog.OpenwireInputMetadata.getRequiredVersion(OpenwireInputMetadata.java:46) [graylog-plugin-openwire-1.1.0.jar:?] at org.graylog2.bootstrap.CmdLineTool.loadPlugins(CmdLineTool.java:297) [graylog.jar:?] at org.graylog2.bootstrap.CmdLineTool.installPluginConfigAndBindings(CmdLineTool.java:269) [graylog.jar:?] at org.graylog2.bootstrap.CmdLineTool.run(CmdLineTool.java:171) [graylog.jar:?] at org.graylog2.bootstrap.Main.main(Main.java:44) [graylog.jar:?]`

I´ve seen other post about the version number on Graylog-plugin.properties. But none of them just an answer Could someone point us to the place were to add the properties?

Thanks for your help
