Ant、jvmarg、系统属性和引号 [英] Ant, jvmarg, system properties and quotes

问题描述

我们有一个属性，其中包含要在 Ant 脚本中传递给 JVM 的一系列参数.

We have a property which contains a series of arguments to be passed to the JVM in an Ant script.

示例(注意第二个条目中的引号):

Example (note the quotes in the second entry):

-Dsql.driver=oracle.jdbc.driver.OracleDriver -Dapp.datasource-properties=URL='jdbc:oracle:thin:@//192.168.56.42:1521/xe':User=user:Password=password  

如果我用 echo 目标打印变量的内容，我会得到预期的结果

If I print the content of the variable with the echo target I get the expected result

<echo message="${jvm.arguments}"/>

生产

-Dsql.driver=oracle.jdbc.driver.OracleDriver -Dapp.datasource-properties=URL='jdbc:oracle:thin:@//192.168.56.42:1521/xe':User=user:Password=password 

然后我将该变量用作 JVM 的参数.

I then use the variable as an argument to the JVM.

示例:

<junit fork="true" forkmode="once" showoutput="true" printsummary="on">
    <jvmarg
        line="-XX:MaxPermSize=256m -Xms1024M ${jvm.arguments}"

引号被悄悄删除.Ant的详细输出给了我

The quotes are silently removed. The verbose output of Ant gives me

[junit] Executing '/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java' with arguments:
[junit] '-XX:MaxPermSize=256m'
[junit] '-Xms1024M'
[junit] '-Dsql.driver=oracle.jdbc.driver.OracleDriver'
[junit] '-Dapp.datasource-properties=URL=jdbc:oracle:thin:@//192.168.56.42:1521/xe:User=user=password'

如何将包含引号的系统属性传递给 JVM?(单人还是双人)?

How can I pass a system property to the JVM containing quotes? (single or double)?

我尝试转义它们，使用双引号无效.

I tried escaping them, using double quotes with no effect.

推荐答案

I use with single value

I use <jvmarg> with single value

 <jvmarg value="-ea"/>
 <jvmarg value="-Dapp.URL=URL=${jvmargs}"/>

然后调用以下行...

 ant tests -Djvmargs=\'jdbc:oracle:thin:@//192.168.56.42:1521/xe\':User=user:Password=password -debug

带有 -debug 的输出包含您期望的行.

The output with -debug has lines expected by you.

 [junit] '-ea'
 [junit] '-Dapp.URL=URL='jdbc:oracle:thin:@//192.168.56.42:1521/xe':User=user:Password=password'

line 用于处理用空格分隔的参数.它可能会进行额外的解析和处理以处理带有空格的输入.我还没有检查代码.

The line is meant to process arguments separated with space. It could be doing additional parsing and processing to handle input with whitespace. I have not checked the code yet.
