我对这个长期问题道歉。
以下是我想用scons
做的事情到目前为止工作的是什么：
什么不起作用：
以下是生成sideLibrary.jar（使用Command）
的scons脚本文件Import('common_env')
#Grab a copy of the top environment (the one sent by the SConstruct file)
common_env = common_env.Clone()
#Current working directory.
currentDir = common_env['ENV']['LOCALROOT'] + '/' + common_env.sconsGetCWD()
#Launches ant -q
tgts = common_env.Command(target = [currentDir + '/dist', currentDir + '/dialogeditor/lib', currentDir + '/doc/sdtk', currentDir + '/obj', common_env['ENV']['LOCALROOT'] + '/LINK/bin/win32/sideLibrary.jar'], source = 'build.xml', action = 'ant -q -f $SOURCE')
#Cleans the generated folders
common_env.Clean(tgts, '')
以下是用于生成语法二进制文件的scons脚本文件（使用自定义构建器）：
Import('common_env')
#Creates a copy of the build environment sent from the SConstruct file.
common_env = common_env.Clone()
#Because this component is only compiled in win32
if (common_env['ENV']['CONFIG'] == "win32"):
#Language of the grammar.
common_env['ENV']['LANGUAGE'] = 'en'
#Language pack.
common_env['ENV']['LANGUAGE_PACK'] = 'English.America.3.3.0'
#Grammar name
common_env['ENV']['GRAMMAR_NAME'] = 'faa'
#Compiles the grammar using a custom builder.
common_env.buildGrammar(src = common_env['ENV']['LOCALROOT'] + '/LINK/bin/win32/sideLibrary.jar')
有人告诉我将 src = common_env ['ENV'] ['LOCALROOT'] +'/ LINK / bin / win32 / sideLibrary.jar'传递给我们的自定义构建器告诉scons他必须在调用buildGrammar之前自动等待sideLibrary.jar。我真的有疑问，因为doc只说：
source：表示要使用的源的Node对象列表 这个构建器函数用于构建目标。
这会带我到Scanner，ParseDepens和Depends（我已经阅读了scons关于它们的文档）。
我不清楚我应该用哪一个来完成我想做的事情：强制编译java组件之前使用-j4编译另一个组件。
有人可以点亮我的灯笼吗？
谢谢

您可能既不需要Scanner，ParseDepends或Depends。请查看我们的ToolsForFools Guide并查看如何为您的构建器提供Emitter。
SCons需要知道的是，文件sideLibrary.jar是由系统中的另一个Builder（整个构建描述）创建的。如果您已经明确指定sideLibrary.jar作为创建构建器的目标，那么这应该是开箱即用的。 SCons然后知道sideLibrary.jar是两个，一个Builder的目标和另一个的源文件。因此，它可以正确安排单个构建步骤...
但是，如果您的sideLibrary.jar只是另一个构建命令的副产品：
env.YourBuilder('other.jar', Glob('*.java'))
，然后你需要为这种类型的构建定义一个特殊的发射器，这样SCons可以看到构建other.jar和创建sideLibrary.jar之间的连接。
我希望这会让事情更加清晰。如果您仍然难以让它发挥作用，请访问我们的UserMailing列表（scons-users@scons.org，另请参阅http://scons.org/lists.html），我们可以更详细地讨论您的问题，您可能会获得更多帮助参考我们文档中的指针。

嗯，我不确定这个问题会对某人有所帮助，但我觉得至少回答我的问题很重要。
所以，对于每个以scons开头的人，总是使用“source =”作为函数参数。我的所有问题（-j4都不能正常工作）与我调用自定义构建器时的情况完全相关，我使用的就是“buildGrammar（src =”blabla“）”。这是错误的。必须是“buildGrammar（source =”blabla“）
