I am developing a java project using Eclipse as IDE and ant as the build tool. For logging I am making use of log4j library. I am able to get the log messages in a log file for my whole application using log4j configuration. But when I build project using ANT, the ANT build messages are still posted to console.I want to make sure that when I build the project, the build messages that ANT generates, like build failure/success, should also be posted to that sames logger file using log4j.
Please help me in this if anyone has got an idea in detail. Thanks
You can make use of Log4jListener available in ant.
Your log4j.properties file would look something like this
log4j.rootLogger=ERROR, LogFile
log4j.logger.org.apache.tools.ant.Project=INFO
log4j.logger.org.apache.tools.ant.Target=INFO
log4j.logger.org.apache.tools.ant.taskdefs=INFO
log4j.logger.org.apache.tools.ant.taskdefs.Echo=WARN
log4j.appender.LogFile=org.apache.log4j.FileAppender
log4j.appender.LogFile.layout=org.apache.log4j.PatternLayout
log4j.appender.LogFile.layout.ConversionPattern=[%6r] %8c{1} : %m%n
log4j.appender.LogFile.file=build.log
And you when you run the ant build you have to pass the listener argument as follows -
ant -listener org.apache.tools.ant.listener.Log4jListener
For the above command to work your log4j.porperites and the log4j jar sould be on the ant classpath. This way your build logs will go to both console and the file build.log

I have a problem with running my jar execution file built by Intellij Idea Artifacts in command line. Error message is
NoClassDefFoundError: io.mattmoore.kotlin.playground.cinterop.Greeter
But it worked when I use the IDE to execute "RUN".
Do you have any Idea why is that happening?
Highly appreciated if someone could give me a hint about how to fix it.

IDE knows better where to find dependencies, but once you export .jar file, you need to manually ensure that no dependency is missing
(and that all get loaded).
Example:
To run MyProgram.jar, place all your dependencies inside of libs directory (which you need to create beside it), then use command like:
java -cp 'MyProgram.jar:libs/*' my_package.MyMainClass
OR for Windows (use semicolon)
java -cp 'MyProgram.jar;libs/*' my_package.MyMainClass
Note that dependency means other .jar files, for example, the one that defines io.mattmoore.kotlin.playground.cinterop.Greeter class.

I have build a JavaFX application which can be executed by its jar file. However if i try to run it using the native exe bundle i am receiving two popups:
Error Invoking method
Failed to launch JVM
and the application fails to start.
The Javafx application is build with intellij ide.
The project structure looks as follows;
when launching the application following popup shows..
The config file looks as follows:-
The packaged jar file is executing properly...
the problem occurs when starting application with launching exe file.
kindly tell me what could went wrong?
UPDATE:
It seems that the build output runtime/bin directory does not contain java.exe file therefore i think the application does not launches.
the output when try to run the application is as follows:
i have build the application with intellij idea, i think there is a problem with that. Kindly look into this matter.
UPDATED:-
Run it from the command line using the runtime that was bundled for you:
If you made an executable Jar (with a proper manifest specifying the classpath and main class)
cd firecap
runtime\bin\java -jar app\libs\your-main.jar
If you don't have an executable jar use something like
cd firecap
runtime\bin\java -cp app\libs\*.* your.main.class.name
Since java.exe is a console program you should be able to see the full error output to get a better idea of what is going wrong.
You very likely have missed including a needed module in the runtime.
It is also possible you ran into a bug that I discovered recently: https://bugs.openjdk.java.net/browse/JDK-8254920
I created my runtime image with this command:
"C:\Program Files\BellSoft\LibericaJDK-15-Full\bin\jlink.exe" --no-header-files --no-man-page, --compress=1 --add-modules java.management,java.logging,javafx.controls,java.xml,java.desktop --output C:\MyProject\build\image\runtime
But yours may be different depending on what modules you need. Note also that I used a JDK from BellSoft that included the JavaFX modules to make it easier.
I am trying to make a new project in maven, but while making the project I am getting "could not calculate build path": plugins error because of this I am not able to work further.
Steps to reproduce:
Launch Eclipse (I am using oxygen) new version
Go to File ->New ->project->select maven as project option
Enter the required filed for POM file
Now, as maven project start building, I am getting the error.
Please find attached screenshot for the reference.
Try the following steps:
Make sure you have connectivity (you can browse) (This kind of error is usually due to connectivity with Internet)
Download Maven and unzip it
Create a JAVA_HOME System Variable
Create an M2_HOME System Variable
Add %JAVA_HOME%\bin;%M2_HOME%\bin; to your PATH variable
Open a command window cmd. Check: mvn -v
If you have a proxy, you will need to configure it
http://maven.apache.org/guides/mini/guide-proxies.html
Make sure you have .m2/repository (erase all the folders and files below)
If you are going to use Eclipse, You will need to create the settings.xml
Maven plugin in Eclipse - Settings.xml file is missing
You can see more detail in
http://maven.apache.org/ref/3.2.5/maven-settings/settings.html
I'm running unit tests in Intellij 14.1.2 with the Gradle plugin. I have external config and test data that is in environment specific in a set of directories (directory for each env). I want to load the config and data via the classpath.
In Eclipse I'd just add the env specific path to the run-config and save the config as:
'Test-XYZ-UAT1'
for example.
In intellij, it seems my application config classpath is tied to my 'module' classpath:
https://www.jetbrains.com/help/idea/2016.3/run-debug-configuration-application.html
how to add directory to classpath in an application run profile in intellij idea?
..which is bad enough but for the Gradle run configs I don't even have the option to add the module classpath.
Run/Debug Configurations window has no:
'Use classpath of mod...'
section.
Question:
How can I set the classpath of the run config when running a Gradle Task within Intellij ?
..and if someone could tell me how to get application run config specific classpaths setup that would be even better.
(please tell me I'm missing something ingenius about Intellij..)
Based on quite a bit of research and trial and error, here is the solution that works for my Kotlin based Spring Boot project.
Background:
My Spring Boot project run configuration is configured to use Run Gradle task in place of the standard IDEA build as its Before launch configuration (see screen shot below).
My Spring Boot project uses src/main/resources/application.properties for JPA and logging properties.
gradle build uses the following output directories for the build. These are the default gradle build output directories for a Kotlin project.
build/classes/kotlin/main for the main class files.
build/classes/kotlin/test for the test class files.
build/resources/main for the main resource files. This is where application.properties is copied during a build.
When I attempted to run this project inside IDEA using the run configuration above, it would fail during Spring Boot start up because it could not find application.properties inside the classpath. When I inspected the classpath used during application startup, build/resources/main was missing.
My Solution
Use the information from: Gradle Goodness: Delegate Build And Run Actions To Gradle In IntelliJ IDEA to delegate IDEA build and execution to Gradle.
When IDEA is configured to delegate build and execution to Gradle, the main and test modules should be configured as follows: On the Paths tab, select Inherit project compile output path.
I'm trying to create an executable jar from IntelliJ.
First I got the Java Security Exception and I changed sqljdbc4-4.0 to unsigned. First problem solved.
Then I got Manifest not found. Added META-INF dir to output. Second problem solved.
Next I got the BeanCreationException (unsolved):
Caused by: org.springframework.beans.factory.BeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath.
In IntelliJ it is working.
I think the resources are not in the output. (application.properties, ...)
In which way do I add the resources or where are they stored in the jar.
I'm using gradle and on the spring boot homepage are only instructions for maven.
You should use spring-boot-maven-plugin or spring-boot-gradle-plugin, depending on your preferred build system.
EDIT:
Just run ./gradlew build
I suggest to dive into this getting started guide. It clarifies a lot of stuff for beginners.
A typical Spring boot project is a Maven project or a Gradle-Project (I only know how to do it with Maven, for Gradle see [luboskrnacs answer][1]). So you just need to run the maven targetpackageand pick the jar form the (created)target` folder
use a shell, go to the project root directory (where the pom.xml file is) and type
mvn clean package
cd target
the there is the xxx.jar file.
