如何编辑 Java 库的构建属性

Question

似乎有一些类似的问题，但没有足够具体的问题，我希望这没问题。

我想知道如何编辑 Jamod MODBUS 库的构建属性，以便使用 RxTx API 而不是已弃用的 javax.comm。图书馆页面说这是支持的：

您需要安装 Java 通信 API 扩展 (javax.comm) 的实现才能运行串行 modbus 应用程序。 请注意，还支持通过布尔构建属性 build.serial.gnu 使用 gnu.io 前缀 (RXTX) 进行构建（true 将导致构建过程在使用的源中将 javax.comm 前缀替换为 gnu.io用于构建）。

更多信息请参见：http://jamod.sourceforge.net/development/project_build.html

我不确定如何访问该文件，或者这样做的技术。我需要创建它还是编辑现有的？我在项目中寻找build.xml，但没有运气，并用谷歌搜索了很多次。非常感谢任何帮助。

Answer 1

只需使用 IDE (例如 Netbeans），然后用 gnu.io 替换所有出现的 javax.comm，来自 rxtx，将 RXTXcomm.jar 库添加到项目中，如果您使用的是 Windows，则将 rxtxSerial.dll 复制到例如 C:\windows\system32。

它会起作用的。祝你好运

The " Modbus Jamod Project - Original " folder contains the original project is available at
Web http://jamod.sourceforge.net/ . This project has a significant dependence :

[1 ] javax.comm : comm : jar :3.0 -u1
Description : The Java Communications 3.0 API is a Java extension That Facilitates develop developing platform -independent communications applications for technologies : such as Smart Cards , embedded systems, and point -of -sale devices , financial services devices , fax , modems, display terminals , and robotic equipment .

This API is not available from Oracle repositories .

That's why you have to open the " Jamod -1.2 -SNAPSHOT - sources.jar " project and recompile using other libraries for serial communication. This project is now ready to " Modbus Jamod Project with CXR " to 64 Bits.




METHOD OF SOLUTION OF DEPENDENCE
-------------------------------------------

To recompile the Jamod (Modbus Jamod Project - Original) project, you must open the project with Netbeans clear the javax.comm library , and replaced with the rxtx library. CXR This library can be selected which are in the " CXR - Serial comms Java " folder , ie :
[1 ] MFZ - rxtx -2.2- 20081207 -linux- i386
[2 ] MFZ - rxtx -2.2- 20081207 -x86_64 -linux
[3 ] MFZ - rxtx -2.2- 20081207 -win- ia64
[4 ] MFZ - rxtx -2.2- x64 -win- 20081207
[5 ] MFZ - rxtx -2.2- x86 -win- 20081207

We must take into account the following when choosing :

Windows
-------

Select a binary build - x64 or x86 (based on Which version of
the JVM you are installing to)

NOTE : You MUST match your architecture . You can not install the i386
version on a 64 - bit version of the JDK and vice - versa.

For a JDK installation:

Copy RXTXcomm.jar ---> <JAVA_HOME> \ jre \ lib \ ext
Copy rxtxSerial.dll ---> <JAVA_HOME> \ jre \ bin
Copy rxtxParallel.dll ---> <JAVA_HOME> \ jre \ bin

Linux
-----

Select a binary build - x86_64 or i386 (based on Which version of
the JVM you are installing to)

NOTE : You MUST match your architecture . You can not install the i386
version on a 64 - bit version of the JDK and vice - versa.

For a JDK installation on i386 architecture =

Copy RXTXcomm.jar ---> <JAVA_HOME> / jre / lib / ext
Copy librxtxSerial.so ---> <JAVA_HOME> / jre/lib/i386 /
Copy librxtxParallel.so ---> <JAVA_HOME> / jre/lib/i386 /

NOTE : For a JDK installation on architecture = x86_64 , just change the
i386 to x86_64 above.

-------------------------------------------------- -----------------------------------------------

After this replace the javax.comm library , the Jamod (Modbus Jamod Project - Original) project is recompiled , and the generated Jar Crossover is added.

When the Crossover project contains the library Jamod repaired , it will have to also add the RXTX library to Crossover.

Done.

Answer 3

如果您在 http://sourceforge.net/projects/jamod/files/jamod/1.2/jamod-1.2rc1-src.zip/download

解压后，你会发现build.xml 和 build-snap.xml，以及 build.properties 文件，它允许您指定 build.serial.gnu。

然后，您只需安装 ant 并在目录中运行它即可启动构建。

编辑：我也没有安装 Apache Forrest，它似乎用于生成文档，因此我还需要注释掉 build.xml 中对 Forrest 的所有引用。
