In the recent use of MAVEN, encountered a problem, with Maven launched the APK has problems can not start, but the idea of packaging is normal.The problem with the log is that there is a problem with one of the resources in the Apklib form of a dependency package. Anti-compilation vs. maven package and idea package to find out where the problem lies.Assumption:

You only need to double-click the .exe file, and the installation prompt is "Next". However, installing a software in linux does not seem so easy, because we are not in the graphic interface.

algorithm, Bloom update operation. I'm not in favor of introducing a new level, such as introducing a cache layer, because it increases maintenance and requires complexity management. The bell also needs to be bell people, since in order to avoid the same IP address pair of the same calculation results, then change the algorithm instead of introducing a new layer, at the same level, compensation is not necessary.All in all, Bloom filter hash algorithm must be kept delicate, occupy space must be

In the Eclipse plug-in development, there is a scenario where you need to set up a resource folder in a plug-in project that contains files such as profiles and templates. The problem that this article describes is that the resource files in the resource folder cannot be accessed after the plug-in project is packaged and published.Problem Recurrence:There are template resource folders at the root of the plug-in project, which need to be accessed when the plug-in is running. In plug-in developmen

generated program is a relatively independent program and does not need any ancillary support files (such as dynamic Runtime Library File DLL ), this shows why all the applications produced by DELPHI are so large. To build a DELPHI Program as small as possible, one method should give full play to the role of Borland package libraries, BPL for short. First, what is a package?In short, a

Why shiny? Shiny allows data analysts to write analysis and visualization code. After a few minutes, they can engineer the analysis code and quickly convert the analysis results into interactive web pages to share with others. Therefore, if you are a data analyst using R, it is wise to choose shiny because it does not require you to have new skills and it is too fast to develop. It is different from other frameworks we usually know: other frameworks are generally separated from the front and bac

When we use BCB to do a program, the next step is to do the packaging program, released to the user. From the point of view of the packaging program, we have a lot of choices, in terms of BCB, each version of the BCB CD has a packaging program, for these packaging procedures, I have only used BCB5 and BCB6, the other version has not been used, do not dare to comment, but the BCB6 with the packaging program obvious problems, Support for Chinese is also not good, so the thought of whether can use

Objective In the previous article we described how to configure the Go development environment under Windows installation. This article describes the directory structure of code Golang, application compilation, custom packages, and references to remote packages. Code directory structure At the end of the Gopath we set the SRC directory is the main directory of our next development program, all the source code is placed under this directory, the general practice is a directory of a project . For

Engineering Catalogue Having learned the above knowledge, we can now complete the planning of a project directory. As an example of writing a command-line program, we typically provide both command-line and API patterns, and we use a three-party package to write code. In addition to the code, a complete program should have its own documentation and test cases. Therefore, a standard engineering directory looks like this below. -/home/user/work
