eclipse - Include one project's jar libraries in another project depending on the first -

-

i working on 2 projects in eclipse.

project depends on jar files come project, , jar files have been added “libraries” tab in project a's “java build path” property in eclipse.

project b depends on project a, directly using classes in of jar files in project a's build path.

i had assumed adding project project b's java build class add jars in project a's build path, appears not case.

do have manually add jars project b's build class, or overlooking setting? if so, why useful standard behaviour?

you have manually add jars project b's classpath.

adding project dependency means project depends on compiled output of project b. project b's output (its compiled .class files) doesn't contain .jar files depends on.

why this? don't know rationale of eclipse authors, guess want keep classpath simple , verbose possible. things can confusing if have multiple versions of same library on classpath.

in vanilla java can provide directory names classpath. when loading class, jvm search these directories in order. eclipse encourages stricter approach each jar specified manually. note can add multiple jars @ once, it's trivial add of project b's jars project a's classpath.

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
