问题 I have a command line app that downloads some reports, processes them, then uploads data to Google Drive. I'm using Typesafe-Config for all the magic strings I need. Typesafe-Config looks on the classpath for my application.conf file and uses HOCON to map config objects to fields in my class, like this: From ~/configs/application.conf : my.homePageUrl = "https://my.home.com" From MyClass.java : private static Config config = ConfigFactory.load(); private static final String HOME_URL = config

问题 When I try to export my project as a runnable jar Eclise gives me the following error: No resources selected. The project runs fine within Eclipse, I already tried to clean the project before exporting, but that didn´t work. Any ideas on how to fix this. 回答1: The problem is most likely with your run configuration. Go to your Class that contains the main(String[] args) method you wish to automatically run when the jar is called from the command line Right-click->Run As...->Application Make

问题 I used eclipse to create executable jar. It relies external other jars. In Eclipse, It is simple that you just need to choose Extract required libraries into generated JAR .

My question is therefore, is there any way to pass vm arguments to the runnable jar not by command line? 回答1: Briefly, you can't do this without some form of wrapper. You can write

问题 I have a JAR file that contains an application as well as configuration files for that application. The application loads configuration files from the classpath (using ClassLoader.getResource() ), and has its dependencies completely satisfied using the configuration files baked into the JAR file. On occasion I want the application to be run with a slightly different configuration (specifically I want to override the JDBC URL to point to a different database) so I create a new configuration

问题 I've got a simple project in Gradle 4.6 and would like to make an executable jar of it. I've tried shadow , gradle-fatjar-plugin , gradle-one-jar , spring-boot-gradle-plugin plugins but neither of them adds my dependencies declared as implementation (I don't have any compile ones).
