Alcatel-Lucent nmake Product Builder

Building Java Code

Dependency-based Java Support

Alcatel-Lucent nmake release lu3.4 introduced dependency-based Java support. The initial phases of support use an external Java scanner to derive dependencies. We are continuing work to expand and improve Java support. Possible future enhancements include a seamless Java dependency scanner and support for other file types.

The dependency-based Java support currently provides the following capabilities. For more information, see the :JAVA: manual page:

• automatic dependency generation
• incremental dependency update
• handles dependency cycles and implicit targets
• optional batched compilations for improved java compilation performance
• concurrent and distributed build **
• incremental global build
• incremental inside package local build
• simplified user interface -- :JAVA: assertion
• concise package level specification -- automatically finds and manages package source given only package hierarchy roots
• viewpathing support
• #empty file filtering

** As of release lu3.6, batched concurrent builds are supported.

Java code can also be built without dependency tracking (see newsletter articles below). We consider the dependency-based solution to be more reliable in keeping the necessary class files up-to-date in incremental builds, thus we recommend projects move to dependency-based Java builds. The non-dependency based solutions may be used for small, simple Java applications or where older versions of nmake must be used.

Jar File Support

Alcatel-Lucent nmake release lu3.6 introduced support for generating jar files. Jar file support includes the following features.

• Support for jdk 1.1.x, 1.2, 1.3, 1.4, 1.5
• viewpathing support
• incremental updates **
• index file **
• manifest file

** When supported by the jdk
