Cannot resolve symbol, but the dependency is in local repo - java
I've been reading all similar problems with maven but I cannot seem to be able to fix it. The issue is the classic "Cannot resolve symbol 'pippo'", in which case pippo is part of
import com.pippo.device.manager.data.model.Device;
This class Device comes from this artifact that I have in my local repo
<dependency>
<groupId>com.pippo</groupId>
<artifactId>device.manager</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
Evidence that it is in the local repository
/mnt/c/Users/sanvegeta/.m2/repository$ find . -type f -name "*device.manager*" -ls
38228 -rwxrwxrwx 1 sanvegeta sanvegeta 39142700 Oct 1 09:00 ./com/pippo/device.manager/0.0.1-SNAPSHOT/device.manager-0.0.1-SNAPSHOT.jar
4 -rwxrwxrwx 1 sanvegeta sanvegeta 1969 Oct 1 08:47 ./com/pippo/device.manager/0.0.1-SNAPSHOT/device.manager-0.0.1-SNAPSHOT.pom
and evidence that this is the correct local repository
mvn help:evaluate -Dexpression=settings.localRepository | grep -v '\[INFO\]'
/mnt/c/Users/sanvegeta/.m2/repository
Just to give you a little bit of context: I'm working on a lab exercise and I created 2 microservices: com.pluto.user.manager and com.pippo.device.manager. They both expose CRUD REST API to work respectively on User and Device. Part of my exercise is to refer to the entity Device from another service (in this case from com.pluto.user.manager) so, in the user.manager, I created an API that is supposed to link the device to the user (it's just adding an id to the user, nothing serious). And the compiler complains. I even tried to create a docker container with jdk, maven and git, and tried to compile there: same problem.
The class where the error appears is the following
package com.pluto.user.manager.controller;
import com.pippo.device.manager.data.model.Device; // problem here
import com.pluto.user.manager.data.model.User;
import com.pluto.user.manager.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;
#RestController
#RequestMapping("/users")
public class UserController {
#Autowired
private UserService userService;
// various CRUD API here
// ...
#PostMapping(path = "/{id}/link", consumes = "application/json", produces = "application/json")
public User link(#PathVariable String id, #RequestBody Device device) {
return userService.linkToDevice(id, device.getId());
}
}
Please, can you help me understand what am I doing wrong?
Edit 1: adding pom.xml of user.manager as requested

Edit 2 (closer to the resolution)
As Stephen suggested, the internal structure of the generated jar file seems wrong. I crafted an alternative jar file with the paths that don't start with BOOT-INF/classes, and the user.manager service compiles and runs just fine.
Now the question is: how do I instruct spring boot to either generate the correct structure or to "see" the classes?
I think you have the wrong dependency. By my reading of the jar -tf output, that looks like a SpringBoot executable JAR file. The Device.class file is there, but its path is not right ... for a normal Java compiler to resolve it:
This:
BOOT-INF/classes/com/pippo/device/manager/data/model/Device.class
needs to be this:
com/pippo/device/manager/data/model/Device.class
I can't find any trace of "com.pippo.*" using Google, so I am guessing that this is a private project.
But if you want use the com.pippo.device.manager classes in other modules, you need to modify its POM file to generate a regular JAR, and use that as the dependency.
One suggestion would be to refactor the existing com.pippo / device.manager project into a SpringBoot project and a (new) regular "library" JAR project, with the former depending on the latter. Put the classes that you want to reuse in com.pluto / project.manager into the "library" project.

attempted to open sandboxed jar as a Trusted-Code but jar is properly signed
I am encountering a very strange behaviour with a Java Web Start application. On one particular machine (windows 7 64 bits, java SE Runtime ENvironment (build 1.7.0-b147)), the application refuses to start with the following error: attempted to open sandboxed jar https://example.com/jnlp/lib/LHC.jar as Trusted-Code The doc suggests that this particular jar contains "untrusted components". I don't know what untrusted components are but after some search it seems to indicate this is linked to particular classes or resources not signed inside the jar. This can't be the case as I get this result with the jarsigner utility: s 6501 Fri Jun 02 11:12:50 CEST 2017 META-INF/MANIFEST.MF 6359 Fri Jun 02 11:12:50 CEST 2017 META-INF/COMPANYBE.SF 4115 Fri Jun

Keeping most recent date from a list of objects
I have an ordered list which is ordered by date, I want to keep the most recent date for each name in the list, for example there may be multiple entries for a name with different dates i want to keep only the most recent for that name,
how can i achieve this for the following list?
I mean a TreeMap which is ordered which maps dates to names, how can i remove for example, there is "Sun Feb 21 00:35:54 GMT 2016=Finley" then there is another "Sun Feb 21 01:03:41 GMT 2016=Finley" at a later date and so on, how could i remove all ones at later dates and only keep the recent ones? but for each name?

I would put the data into a HashMap (name->date). If an entry for the name already exists, overwrite it if the date is more recent. In case you have trouble comparing the dates, use DateFormat to convert the strings into Date objects which you can compare.

How to to autodeploy war file with GlassFish -- from "Core JavaServerFaces" by David Geary, Cay S. Horstmann
Naive question, but this is my first step in JSF, so forgive me ;-) I am following all the steps of the first example from "Core JavaServerFaces" by David Geary, Cay S. Horstmann (the 3rd edition). What works in general: java works glassfish works I can compile the attached code I can create .war file The problem begins when I copy the war file into autodeploy subdirectory of GlassFish and try to show the appropriate page in GF. In return I get 404 error and in logs I find this: Selecting file /opt/glassfish3/glassfish/domains/domain1/autodeploy/login.war for autodeployment. Module type not recognized for module /opt/glassfish3/glassfish/domains/domain1/applications/login There is no installed container capable of handling this application login Autodeploy failed : /opt/glassfish3/glassfish/domains/domain1/autodeploy/login.war. glassfish 3.1.2, java 1.6.0_29, opensuse 11.4.

Your WAR file is broken. Package it up in the web folder instead. WEB-INF should be in the root.
How to get folder paths inside a jar file?
Okay, so in the IDE it runs great and says the file exists, but once I pack it into a jar this code:
File levelFolder = new File(getClass().getResource("data/level").getPath());
System.out.println("exists = " + levelFolder.exists());
says the folder doesn't exist. any idea why?

G:\java>
generally it's because the class you getClass()'d is in package com.something.app, and so with a relative path your data has to be in com/something/app/data/level. Otherwise use an absolute path.
To see where things are in your jarfile:
jar tvf myapp.jar
[ok, after a lot of back-and-forth and some testing]...
jcomeau#intrepid:/tmp$ cat test.java; java -cp test.jar test; jar tvf test.jar
import java.io.*;
public class test {
public static void main(String[] args) {
//System.out.println(test.class.getResource("data/level"));
try {
System.out.println(new File(test.class.getResource("data/level").getPath()));
System.out.println(test.class.getResourceAsStream("data/level/test").read());
} catch (Exception whatever) {
System.err.println("error: " + whatever);
}
}
}
file:/tmp/test.jar!/data/level
116

I'm too tired to continue, but main() prints 116, which is the ASCII value of "t", the result of read() which reads in the first byte. That should be enough to prove that getResourceAsStream() will enable you to access your resources. There ought to be a way to do it with File() also, but the path returned is strange with that '!' separating the path to the jarfile with the path inside the jarfile. I've never dealt with that before.
Enumeration<URL> resources = getClass().getClassLoader().getResources("data/level");
System.out.println("exists = " + resources.hasMoreElements());
