[英]How to add system property equivalent to java -D in Ant
I need to set java -Djava.library.path=/some/path and I want to do it when I am running my ant script, building my jar. 我需要设置java -Djava.library.path = / some / path ,我想在运行我的ant脚本,构建我的jar时这样做。
I think I have to use 我想我必须使用
<sysproperty key="java.library.path" value="/some/path"/>
but it doesnt work. 但它不起作用。 I cannot make the syntax work.
我不能使语法工作。 The only thing I have Googled and found is sysproperty in conjunction with
我用Google搜索和找到的唯一东西就是sysproperty
<java classname>
but that doesnt make any sense to me. 但这对我没有任何意义。
I am not sure if this is relevant, but I am using ant to create a ear and deploying this ear in JBoss. 我不确定这是否相关,但我使用ant来创建一个耳朵并在JBoss中部署这个耳朵。
Here is an example Ant target run
that executes the example.jar
and passes a system property with key="java.library.path"
and value="/some/path"
: 下面是一个示例Ant目标
run
,它执行example.jar
并传递一个系统属性,其中key="java.library.path"
和value="/some/path"
:
<target name="run">
<java jar="example.jar" fork="true">
<jvmarg value="-Djava.library.path=/some/path"/>
</java>
</target>
你试过跑吗?
ant -Djava.library.path=/some/path ... ?
I found out how I can solve this. 我发现了如何解决这个问题。
Seems like since we are using ant to create and deploy our application in a Application Server (Web Server), in our case JBoss, we had to modify 似乎是因为我们使用ant在Application Server(Web Server)中创建和部署我们的应用程序,在我们的JBoss案例中,我们必须修改
run.shand add the java.library.path as a VM argument there.
Something like this: 像这样的东西:
JBOSS_NATIVE_DIR="$JBOSS_NATIVE_DIR:/usr/lib/ure/lib/" JAVA_OPTS="$JAVA_OPTS -Djava.library.path=$JBOSS_NATIVE_DIR"
Thus, it is not correct to pass in VM arguments in ant. 因此,在ant中传递VM参数是不正确的。
