Followed is my project structure.
com.company.univ.scheduler.api
--src
----com
-----company
-------univ
--------scheduler
----------api
------------annotation
---Column.java
---Id.java
---pom.xml
-------------model
----App.java
----job.java
----Task.java
----pom.xml
-------------service
----LockService.java
----ResultService.java
----TaskService.java
----pom.xml
Under model folder,the App.java will have to import annotation's java file.
Like
import com.company.univ.scheduler.api.Column;
import com.company.univ.scheduler.api.Id;
Likewise,all files distributed under various folder would be related.How would maven pom.xml handle this issue?
P.S When do maven compile,there always show error message like"can not find symbol;"
"method can not be override"..... I have checked those java files to the target line but no that obvious errors likely to happen,As our project was build in Ant before and all fine.
The maven compile info:
[ERROR] COMPILATION ERROR :
[INFO]-------------------------------------------------------

Java source should be in src/main/java, which is the root of your package hierarchy.
I would strongly urge you to use the standard Maven directory layout.
Why are there pom files in each of your packages?

Build is failing when I did a change in Java file
Android Gradle Plugin: 3.2.1
Gradle Version: 4.6
Please find the snapshot of error below:
17:58:31.131 [ERROR] [system.err] symbol: class FragmentNavigationManager
17:58:31.132 [ERROR] [system.err] location: package com.microsoft.office.officemobile.FragmentManagerInfra
17:58:31.138 [ERROR] [system.err] D:\Office\dev\officemobile\android\Java\src\com\microsoft\office\officemobile\ActionsTab\ActionsAdapter.java:45: error: cannot find symbol
17:58:31.138 [ERROR] [system.err] import com.microsoft.office.officemobile.KaizalaPhoneauth.KaizalaPhoneAuthManager;
I checked the undefined symbols are present inside file FragmentNavigationManager.java file inside the sources.
Using debug logs, I found the class file FragmentNavigationManager.class is getting deleted before doing java build
gradle: 17:58:28.630 [DEBUG] [org.gradle.api.internal.file.delete.Deleter] Deleting d:\office\build\droidarm\ship\officemobile\android\java\intermediates\javac\release\compileReleaseJavaWithJavac\classes\com\microsoft\office\officemobile\FragmentManagerInfra\FragmentNavigationManager.class
After deletion of above class, while doing Java incremental build, FragmentNavigationManager.java should be passed as an input for javac, but it is not happening, which is causing undefined symbol issue. Clean build working fine
I found the issue
The source file path is: src\com\microsoft\office\officemobilefragmentmanagerinfra\FragmentNavigationManager.java
Generated Class file: intermediates\javac\release\compileReleaseJavaWithJavac\classes\com\microsoft\office\officemobileFragmentManagerInfra\FragmentNavigationManager.class
There is a case mismatch in directory name at source path and generated class path, which is causing the issue. Source path has fragmentnavigationmanager instead of FragmentNavigationManager
I found that the package name is: com.microsoft.office.officemobile.FragmentManagerInfra.FragmentNavigationManager. Changing directory name to match the package name at the source path resolves the issue
Is this expected, as full build is working fine and incremental Gradle build is only failing?
Working on Windows 10
The question is simple, but I spent the last 2 days trying to deploy my app. And so far it doesn't.
I have a single CSS file for my style, and when I execute the jar, CSS is not found (404) or the jar won't package.
As stated here: Spring Boot Executable jar structure
"Do not use the src/main/webapp folder if your application will be packaged as a jar"
and
"You should place your static resources in src/main/resources instead."
so put the CSS here:
src/main/resources/styles.css
In Vaadin documentation (which is very pour on how to package...) I import the CSS like this:
#StyleSheet("styles.css")
Source : https://vaadin.com/docs/v11/flow/importing-dependencies/tutorial-include-css.html
Then I package my project:
mvn clean package -Pproduction
I get this error:
[ERROR] Failed to execute goal com.vaadin:vaadin-maven-plugin:11.0.0:package-for-production (default) on project importparcoursup: Execution default of goal com.vaadin:vaadin-maven-plugin:11.0.0:package-for-production failed: An import that ends with 'styles.css' cannot be resolved: the corresponding file 'C:\Workspace\lasteclipeandjava10\parcoursup\target\frontend\styles.css' was not found.
[ERROR] Double check the corresponding import and verify the following:
[ERROR] * the import string is correct
[ERROR] * the file imported is either present in 'frontend://' directory of the project or in one of the project WebJar dependencies or in one of the regular jar dependencies
[ERROR] * if the file is present in one of the regular jar dependencies, it should be located in META-INF/resources/frontend directory in the jar
Can someone provide a simple example of a 'springboot + Vaadin10' app packaged as a jar with static resources inside ?
I tried so many configurations (put the CSS in META-INF, include webapp resources in the maven build process...) but after 2 days, I still can't deploy my app on the server!
finally the solution
css has to be here:
src/main/resources/META-INF/resources/frontend/styles.css
then declared as:
#StyleSheet("frontend://styles.css")
This could be helpful too even though I still miss an example:
Vaadin 10 makes some changes to the way it loads static resources,
such as application templates, custom styles and any additional
JavaScript files. The gist of it is that such files should be put in
src/main/webapp/frontend/ when building a .war file and
src/main/resources/META-INF/resources/frontend/ when building a .jar
file.
Link to Vaadin Dokumentation: Vaadin 10 and static resources
Am trying to work with the Hyperlegder Java SDK but am unable to locate the Shim-client jar. See error below.
Information:java: Errors occurred while compiling module 'maven'
Information:javac 1.8.0_74 was used to compile java sources

Error:(11, 35) java: package org.hyperledger.fabric.shim does not exist
Error:(12, 35) java: package org.hyperledger.fabric.shim does not exist
All the sources i see online require me to download the source from a missing Git repo -≥ https://github.com/hyperledger/fabric/core/chaincode/shim/java
Edit: The source URL is https://github.com/hyperledger/fabric/tree/release/core/chaincode/shim/java
Was able to download the repo and gradle build to get the JAR file.
use bellow dependency
<dependency>

<artifactId>fabric-java-sdk</artifactId>
<version>0.6.6</version>
</dependency>
my current problem is that I am trying to configure Jenkins with the built-in Sonar.
My structure in SVN is as following:
--/
--parent
--pom.xml ( modules are defined in this order
<module>../common</module>
<module>../model</module>
<module>../persistence</module>
<module>../services</module>
<module>../webservices-model</module>
<module>../webservices</module>
<module>../web</module>
<module>../fidb-client</module>
<module>../batch</module> )
--common ( every modul has its own pom.xml as well! )
--pom.xml
--model
--persistence
--services
--webservices-model
--webservices
--web
Now what I tried:
In Jenkins under source code management I specified the repository url as: `http://xyz/svn/parent/`
Local module directory: `./parent`
I did this for every module defined above.
Prepare SonarQube Scanner environment is checked
Root POM: `pom.xml`
Invoke top level Maven targets ( I did this for every modul as well )
-Dsonar.host.url=$SONAR_HOST_URL
-Dsonar.login=test
-Dsonar.password=test
-Dhttp.proxyHost=proxy.net
-Dhttp.proxyPort=8080
-Dhttp.nonProxyHosts=test.lan.at
-f ../parent/pom.xml clean install
However, I always get the following error when trying to build at the persistence modul ( common, modul and paret are working ), in Eclipse, however, it works without problems:
ERROR] Failed to execute goal on project mifid2-persistence: Could not resolve dependencies for project at.sitsolutions.mifid2:mifid2-persistence:jar:1.0.0-SNAPSHOT: The following artifacts could not be resolved: at.sitsolutions.mifid2:mifid2-fidb-client:jar:1.0.0-SNAPSHOT, com.oracle:ojdbc7:jar:12.1.0.2: Could not find artifact at.sitsolutions.mifid2:mifid2-fidb-client:jar:1.0.0-SNAPSHOT -> [Help 1]
Maybe, someone can tell me what I am doing wrong.
Thanks for your help
I have installed grails and am trying to compile with the default version of cache:1.1.6 and I'm getting these errors within the plugin code.
Can any one help me with which dependency is broken in the repository - I havent even used the cache yet - just defined it in BuildConfig.groovy
I understand "By default, Grails will not only get the JARs and plugins that you declare, but it will also get their transitive dependencies" so why would I have to declare the dependencies?
Compilation error: startup failed:
Compile error during compilation with javac.

Odd this is with a new Grails application? It sounds like it could be a corrupt Maven cache issue. Try doing:
$ rm -rf ~/.m2/repository
Otherwise, to declare the dependency explicitly edit BuildConfig and add:
compile 'org.springframework:spring-aop:4.0.5.RELEASE'
To your dependencies block.
