Netbeans 无法在不同操作系统上创建的项目中编译 JSP

Question

当项目在不同的操作系统上创建时，在netbeans +7.2中编译项目时发生下一个错误

compile-jsps:

这是一个问题，Netbeans 如何使用 sysClasspath 参数调用 JspC apache 编译器。您可以在 netbeans bug #198480 上查看 mor 信息

我个人更喜欢将构建系统更改为 Maven，但这是一个庞大而复杂的项目。此外，我不想修改系统生成的文件，如 build-impl.xml，所以我更愿意等待将来的 NB 更新会破坏（或修复）某些东西，然后手动更新属性文件。

我使用自定义 build.xml 修改而不更改 build-impl.xml 来搜索并改进此错误中的解决方案。下一个代码解决了我的问题：

<!-- workaround bug https://netbeans.org/bugzilla/show_bug.cgi?id=198480 -->
<target name="checkos">
    <echo message="OS Name is:         ${os.name}"/>
    <echo message="OS Architecture is: ${os.arch}"/>
    <echo message="OS Version is:      ${os.version}"/>
    <condition property="is_windows">
        <os family="windows"/>
    </condition>
    <condition property="is_linux">
        <os family="unix"/>
    </condition>
</target>
<target name="patch-bug-198480-windows" if="is_windows" depends="checkos">
    <copy file="lib/nblibraries-syscp-windows.properties" tofile="lib/nblibraries-private.properties"/>
</target>
<target name="patch-bug-198480-linux" if="is_linux" depends="checkos">
    <copy file="lib/nblibraries-syscp-linux.properties" tofile="lib/nblibraries-private.properties"/>
</target>

<target name="-post-clean">
    <delete file="lib/nblibraries-private.properties"/>
</target>

    <target name="-pre-init" depends="patch-bug-198480-windows,patch-bug-198480-linux">

我考虑到 libs.jsp-compilation-syscp.claspath 仅在 buidl-impl.xml 中的两个地方使用，并且此修改不会改变行为

文件 nblibraries-syscp-linux.properties

libs.jsp-compilation-syscp.classpath=\
    ${base}/jsp-compilation-syscp/ant.jar:\
    ${base}/jsp-compilation-syscp/servlet3.1-jsp2.3-api.jar:\
    ${base}/jsp-compilation-syscp/glassfish-jspparser-4.0.jar:\
    ${base}/jsp-compilation-syscp/jstl-impl.jar:\
    ${base}/jsp-compilation-syscp/javax.faces.jar
libs.jsp-compilation-syscp.displayName=JSP Compilation Sysclasspath

文件 nblibraries-syscp-windows.properties

libs.jsp-compilation-syscp.classpath=\
    ${base}/jsp-compilation-syscp/ant.jar;\
    ${base}/jsp-compilation-syscp/servlet3.1-jsp2.3-api.jar;\
    ${base}/jsp-compilation-syscp/glassfish-jspparser-4.0.jar;\
    ${base}/jsp-compilation-syscp/jstl-impl.jar;\
    ${base}/jsp-compilation-syscp/javax.faces.jar
libs.jsp-compilation-syscp.displayName=JSP Compilation Sysclasspath

重要提示：您应该记住在 NetBeans 升级时更新这些文件
