1 | ========================
2 | BUILD OUTPUT DESCRIPTION
3 | ========================
4 |
5 | When you build an Java application project that has a main class, the IDE
6 | automatically copies all of the JAR
7 | files on the projects classpath to your projects dist/lib folder. The IDE
8 | also adds each of the JAR files to the Class-Path element in the application
9 | JAR files manifest file (MANIFEST.MF).
10 |
11 | To run the project from the command line, go to the dist folder and
12 | type the following:
13 |
14 | java -jar "curve-line-chart.jar"
15 |
16 | To distribute this project, zip up the dist folder (including the lib folder)
17 | and distribute the ZIP file.
18 |
19 | Notes:
20 |
21 | * If two JAR files on the project classpath have the same name, only the first
22 | JAR file is copied to the lib folder.
23 | * Only JAR files are copied to the lib folder.
24 | If the classpath contains other types of files or folders, these files (folders)
25 | are not copied.
26 | * If a library on the projects classpath also has a Class-Path element
27 | specified in the manifest,the content of the Class-Path element has to be on
28 | the projects runtime path.
29 | * To set a main class in a standard Java project, right-click the project node
30 | in the Projects window and choose Properties. Then click Run and enter the
31 | class name in the Main Class field. Alternatively, you can manually type the
32 | class name in the manifest Main-Class element.

151 |
152 | The J2SE Platform is not correctly set up.
153 | Your active platform is: ${platform.active}, but the corresponding property "platforms.${platform.active}.home" is not found in the project's properties files.
154 | Either open the project in the IDE and setup the Platform with the same name or add it manually.
155 | For example like this:
156 | ant -Duser.properties.file=<path_to_property_file> jar (where you put the property "platforms.${platform.active}.home" in a .properties file)
157 | or ant -Dplatforms.${platform.active}.home=<path_to_JDK_home> jar (where no properties file is used)
