As part of polishing the radiology project forked from OpenMRS, I’m trying to create a docker image on `lh-toolkit` using the [lh-toolkit-legacy-ui](https://gitlab.com/sunbiz/lh-toolkit-legacyui) by @sunbiz. I get the following exception when building the image. ``` java.lang.NullPointerException 23:36:21.133 TC> at org.openmrs.module.ModuleFileParser.parse(ModuleFileParser.java:276) 23:36:21.134 TC> at org.openmrs.module.ModuleFactory.getModuleFromFile(ModuleFactory.java:535) 23:36:21.134 TC> at org.openmrs.module.ModuleFactory.loadModule(ModuleFactory.java:107) 23:36:21.141 TC> at org.openmrs.module.ModuleFactory.loadModules(ModuleFactory.java:193) 23:36:21.141 TC> at org.openmrs.module.ModuleFactory.loadModules(ModuleFactory.java:173) 23:36:21.141 TC> at org.openmrs.module.ModuleUtil.startup(ModuleUtil.java:77) 23:36:21.142 TC> at org.openmrs.api.context.Context.startup(Context.java:832) 23:36:21.142 TC> at org.openmrs.web.Listener.startOpenmrs(Listener.java:244) 23:36:21.142 TC> at org.openmrs.web.WebDaemon$1.run(WebDaemon.java:42) 23:36:21.172 TC> ERROR - ModuleFactory.getModuleFromFile(539) |2017-01-24 22:36:21,143| Error getting module object from file legacyui-1.2-SNAPSHOT.omod 23:36:21.172 TC> org.openmrs.module.ModuleException: Unable to get jar file Module: legacyui-1.2-SNAPSHOT.omod 23:36:21.173 TC> at org.openmrs.module.ModuleFileParser.parse(ModuleFileParser.java:146) 23:36:21.174 TC> at org.openmrs.module.ModuleFactory.getModuleFromFile(ModuleFactory.java:535) 23:36:21.174 TC> at org.openmrs.module.ModuleFactory.loadModule(ModuleFactory.java:107) 23:36:21.181 TC> at org.openmrs.module.ModuleFactory.loadModules(ModuleFactory.java:193) 23:36:21.181 TC> at org.openmrs.module.ModuleFactory.loadModules(ModuleFactory.java:173) 23:36:21.181 TC> at org.openmrs.module.ModuleUtil.startup(ModuleUtil.java:77) 23:36:21.181 TC> at org.openmrs.api.context.Context.startup(Context.java:832) 23:36:21.181 TC> at org.openmrs.web.Listener.startOpenmrs(Listener.java:244) 23:36:21.182 TC> at org.openmrs.web.WebDaemon$1.run(WebDaemon.java:42) 23:36:21.182 TC> Caused by: java.util.zip.ZipException: error in opening zip file 23:36:21.182 TC> at java.util.zip.ZipFile.open(Native Method) 23:36:21.182 TC> at java.util.zip.ZipFile.(ZipFile.java:219) 23:36:21.194 TC> at java.util.zip.ZipFile.(ZipFile.java:149) 23:36:21.194 TC> at java.util.jar.JarFile.(JarFile.java:166) 23:36:21.194 TC> at java.util.jar.JarFile.(JarFile.java:130) 23:36:21.194 TC> at org.openmrs.module.ModuleFileParser.parse(ModuleFileParser.java:142) 23:36:21.195 TC> ... 8 more 23:36:22.319 TC> WARN - Module.expandExtensionNames(574) |2017-01-24 22:36:22,314| webservices.rest: Unable to find class definition for extension: org.openmrs.admin.list 23:36:22.319 TC> java.lang.NoClassDefFoundError: org/openmrs/module/web/extension/AdministrationSectionExt 23:36:22.320 TC> at java.lang.ClassLoader.defineClass1(Native Method) 23:36:22.321 TC> at java.lang.ClassLoader.defineClass(ClassLoader.java:763) 23:36:22.322 TC> at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) 23:36:22.327 TC> at java.net.URLClassLoader.defineClass(URLClassLoader.java:467) 23:36:22.329 TC> at java.net.URLClassLoader.access$100(URLClassLoader.java:73) 23:36:22.329 TC> at java.net.URLClassLoader$1.run(URLClassLoader.java:368) 23:36:22.329 TC> at java.net.URLClassLoader$1.run(URLClassLoader.java:362) 23:36:22.341 TC> at java.security.AccessController.doPrivileged(Native Method) 23:36:22.341 TC> at java.net.URLClassLoader.findClass(URLClassLoader.java:361) 23:36:22.341 TC> at org.openmrs.module.ModuleClassLoader.loadClass(ModuleClassLoader.java:637) 23:36:22.341 TC> at org.openmrs.module.ModuleClassLoader.loadClass(ModuleClassLoader.java:556) 23:36:22.341 TC> at java.lang.ClassLoader.loadClass(ClassLoader.java:357) 23:36:22.341 TC> at org.openmrs.module.Module.expandExtensionNames(Module.java:566) 23:36:22.341 TC> at org.openmrs.module.Module.getExtensions(Module.java:494) 23:36:22.342 TC> at org.openmrs.module.ModuleFactory.startModuleInternal(ModuleFactory.java:698) 23:36:22.342 TC> at org.openmrs.api.context.Daemon$1.run(Daemon.java:74) 23:36:22.342 TC> Caused by: java.lang.ClassNotFoundException: org.openmrs.module.web.extension.AdministrationSectionExt 23:36:22.342 TC> at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1892) 23:36:22.342 TC> at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1735) 23:36:22.342 TC> at org.openmrs.module.ModuleClassLoader.loadClass(ModuleClassLoader.java:563) 23:36:22.342 TC> at java.lang.ClassLoader.loadClass(ClassLoader.java:357) 23:36:22.342 TC> ... 16 more ``` Same exception is thrown when using [this](https://gitlab.com/sunbiz/lh-toolkit-docker/blob/master/modules/webservices.rest-2.17-SNAPSHOT.32bae9.omod) `webservices.rest-2.17-SNAPSHOT.32bae9.omod` from @sunbiz. But _it works fine_ using OpenMRS’ `legacy-ui` and `webservices`. Any help here? ---

Looks like a corrupt omod or zip. Can you open it using a zip viewer like 7zip?
