eclipse 运行外部工具launch

eclipse java项目当中的externalToolBuilders目录是自动生成的环境相关的配置信息：
比如里面的build.xml内容如下：
文件信息如下：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<launchConfiguration type="org.eclipse.ui.externaltools.ProgramBuilderLaunchConfigurationType">
<stringAttribute key="org.eclipse.debug.core.ATTR_REFRESH_SCOPE" value="${resource}"/>
<booleanAttribute key="org.eclipse.debug.ui.ATTR_LAUNCH_IN_BACKGROUND" value="false"/>
<booleanAttribute key="org.eclipse.ui.externaltools.ATTR_BUILDER_ENABLED" value="true"/>
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_BUILD_SCOPE" value="${working_set:<?xml version="1.0"
encoding="UTF-8"?> <resources> <item path="/native-audio" type="4"/> </resources>}"/>
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_LOCATION" value="D:/android-software/cygwin/bin/bash.exe"/>
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_RUN_BUILD_KINDS" value="full,incremental,auto,clean"/>
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_TOOL_ARGUMENTS" value="--login -c "cd /cygdrive/e/eclipse/app/native-audio && ndk-build""/>
<booleanAttribute key="org.eclipse.ui.externaltools.ATTR_TRIGGERS_CONFIGURED" value="true"/>

<!--直接到哪个目录下-->
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_WORKING_DIRECTORY" value="D:/android-software/cygwin/bin"/>
</launchConfiguration>

配置文件的调用方式：

1.新建一个launch类，继承LaunchConfiguration

2.使用DebugUITools.launch(config, "run");执行即可弹出框
