[英]Running Java from Apple Script
I am very new to Apple scripting so please bear with me.我对 Apple 脚本很陌生,所以请耐心等待。 I need to run a
.jar
file using applescript
, the jar
is not executable so I invoke the class
like com.path.to.myClass
.我需要使用
applescript
运行一个.jar
文件,该jar
是不可执行的,所以我调用了com.path.to.myClass
之class
类。 My Apple script looks like below-我的 Apple 脚本如下所示-
display alert "You are about to start the image rename process." buttons {"OK", "Cancel"}
set theAnswer to button returned of the result
if theAnswer is "OK" then
do shell script "java -classpath ./ImageRename_JAVA-1.0.0.jar:. com.mff.image.rename.Main"
else
say "Exit"
end if
Both the applescript and the ImageRename_JAVA-1.0.0.jar
are in the same directory, but when I run the script it gives me an error- ImageRename_JAVA-1.0.0.jar
和ImageRename_JAVA-1.0.0.jar
都在同一个目录中,但是当我运行脚本时,它给了我一个错误-
error "Exception in thread \"main\" java.lang.NoClassDefFoundError: com/mff/image/rename/Main
Caused by: java.lang.ClassNotFoundException: com.mff.image.rename.Main
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)" number 1
Am I setting the classpath
wrong?我设置的
classpath
错误吗? If so, what is the correct way?如果是这样,正确的方法是什么? Also, how can I add more
jar
s to the classpath
?另外,如何向
classpath
添加更多jar
?
When I run the below command from Terminal
it runs just fine.当我从
Terminal
运行以下命令时,它运行得很好。
$ java -classpath ./ImageRename_JAVA-1.0.0.jar:. com.mff.image.rename.Main
I know that it can be done in a better way using JAR Bundler
but I have no control over the JAR
and its developed by someone else.我知道使用
JAR Bundler
可以更好地完成它,但我无法控制JAR
及其由其他人开发的。 Is there a way that I can include all the JAR
s inside the application under YourApplicationName.app/Contents/MacOS/Resources/Java/
directory and use those in the class path.有没有一种方法可以将所有
JAR
包含在YourApplicationName.app/Contents/MacOS/Resources/Java/
目录下的应用程序中,并在类路径中使用它们。
I don't think you can guarantee what the working directory is in a do shell script
, but you can work it out with something like this:我认为您不能保证
do shell script
的工作目录是什么,但是您可以使用以下方法解决它:
set scriptPath to the POSIX path of (path to me)
do shell script "SCRIPTDIR=`dirname " & scriptPath & "` ; " ¬
& "java -classpath $SCRIPTDIR/ImageRename_JAVA-1.0.0.jar:$SCRIPTDIR com.mff.image.rename.Main"
To add extra JARs to the classpath you can take advantage of a shortcut provided by the java
command whereby a classpath entry ending in *
includes all .jar
files in the given directory.要将额外的 JAR 添加到类路径,您可以利用
java
命令提供的快捷方式,其中以*
结尾的类路径条目包括给定目录中的所有.jar
文件。
do shell script "java -classpath " ¬
& "/Applications/Something.app/Contents/Resources/Java/\\* com.example.MyClass"
The *
needs to be backslash escaped to protect it from expansion by the shell, and the backslash itself needs to be backslash-escaped when it is within an AppleScript string literal, hence the \\\\*
. *
需要被反斜杠转义以防止它被shell扩展,当它在AppleScript字符串文字中时,反斜杠本身需要被反斜杠转义,因此\\\\*
。
