[英]Apache Ant gets frozen while running this script
I want to show a password input dialog from ant script. 我想从ant脚本中显示一个密码输入对话框。 Here's my code from build.xml :
这是我在build.xml中的代码:
<target name="sign" unless="isUpToDate">
<script language="javascript">
importClass(javax.swing.JPasswordField);
importClass(javax.swing.JOptionPane);
var pf = new JPasswordField();
var okCxl = JOptionPane.showConfirmDialog(null, pf, "Enter Password", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);
if (okCxl == JOptionPane.OK_OPTION) {
project.setNewProperty("keypass", pf.getPassword());
} else {
throw "Password is required";
}
</script>
<echo message="${keypass}"></echo>
...
</target>
This code hangs forever. 这段代码永远挂起。 What's wrong?
怎么了?
Update: I'm testing in Mac OS X 10.8.2 and Oracle JDK 7u13 更新:我正在使用Mac OS X 10.8.2和Oracle JDK 7u13进行测试
It works well in Eclipse Juno Release Build id: 20120614-1722 and JDK 7 under Windows XP: 它在Eclipse Juno Release Build id:20120614-1722和Windows XP下的JDK 7中运行良好:
Buildfile: D:\...\build.xml
sign:
[echo] [C@ea1569
BUILD SUCCESSFUL
Total time: 7 seconds
And it works well from Run.bat : 它从Run.bat运行良好:
D:\>call d:\ant\bin\ant
Buildfile: D:\...\build.xml
sign:
[echo] [C@12a642
BUILD SUCCESSFUL
Total time: 8 seconds
But getPassword() returns char[] not String, this is because the echo is not human readable. 但是getPassword()返回char []而不是String,这是因为echo不是人类可读的。
As an alternative, put the storepass
required by <signjar />
in an invisible file, eg .deployconf
, having user-only access: eg 400
or 600
. 作为替代方案,将
<signjar />
所需的storepass
放在一个不可见的文件中,例如.deployconf
,具有用户访问权限:例如400
或600
。 Load the password in ant
, and use as required: 在
ant
加载密码,并根据需要使用:
<loadfile srcfile="${user.home}/.deployconf" property="deployconf"/>
This works well with <signjar />
, although some effort may be required to keep linefeeds out of .deployconf
. 这适用于
<signjar />
,尽管可能需要一些努力来保持.deployconf
换行符。
