Netbeans Dev（9.x）的Java项目无法在Netbeans之外构建

javanetbeansantjava-9

我们使用Netbeans生成我们的Ant构建文件，并进行了一些小的调整。这使我们能够在Netbeans内部构建项目，并在命令行上运行ant以构建我们的项目，后者对于诸如完全重建或Jenkins持续构建和测试等事情非常有用。
我们根据需要自定义我们的build.xml文件，在Netbeans 8.2及之前的版本中很好地工作，但是在Netbeans pre-9（包括201708280001版的Dev版本）中，Netbeans开始在命令行上运行时破坏我们的构建。
我们会得到以下错误：
BUILD FAILED
C:\Users\Stephen\hcs\orc.trunk\nb\build.xml:278: The following error occurred while executing this line:
C:\Users\Stephen\hcs\orc.trunk\nb\build.xml:229: The following error occurred while executing this line:
C:\Users\Stephen\hcs\orc.trunk\nb\ServerLibWOC\nbproject\build-impl.xml:1623: Unknown attribute [modulepath]

Total time: 2 minutes 35 seconds

当在Netbeans中构建时，它可以正常工作。
如果我手动查看所有的build-impl.xml文件，我可以删除modulepath引用并使构建在命令行和Netbeans上正常工作，但最终Netbeans会重新引入modulepath设置。因此，这不是一个令人满意的长期解决方案。
我尝试升级到最新版本的Ant（1.9.9）和Netbeans Dev，但没有效果。我假设Netbeans使用的某个库在我的标准Ant 1.9.9中不存在，但我不知道是什么。
有人找到了一种解决方案，允许Ant从命令行正确构建Netbeans项目吗？
更新1：
使用Ant 1.10.1尝试，结果相同。
更新2：
在Java 9下运行命令行Ant未解决问题。
更新3：
将我的测试隔离到一个项目（orcb）中，并确保它在Java9下运行。仍然失败：

请注意有关源1.6的警告，这是Java9中的新警告。这是因为我们需要构建代码，以便在旧的JVM下运行（我们不能成功地强制客户升级）。
build.sh的内容如下：
$ cat build.sh
export JAVA_HOME=/cygdrive/c/jdk1.9.ea
"c:/Program Files (x86)/NetBeans Dev 201709180002/extide/ant/bin/ant" -Dplatforms.JDK32_1.6.home=c:/jdk1.6.0_43 -Dplatforms.JDK32_1.7.home=C:/jdk_1.7.0_79/ -Dlibs.CopyLibs.classpath=C:/Users/Stephen/hcs/orc.trunk/lib/netbeans/org-netbeans-modules-java-j2seproject-copylibstask.jar clean jar compile-test

注意: 平台参考用于确保我们正确地构建与旧版本的Java相对应的应用程序。
向Netbeans提交了一个工单: https://netbeans.org/bugzilla/show_bug.cgi?id=271487 更新4:
新工单: https://issues.apache.org/jira/browse/NETBEANS-1106 更新5:
这也影响到 Netbeans 11，如果您使用 Java 1.8 或更早版本，则无法在 Netbeans 中正确构建。
请在命令行中输入java -version，查询您的Java版本，并告知出现错误时的版本信息。另外，请问NetBeans使用的Java版本是多少？ - Naman
命令行上的Ant正在Java 1.8.0_73下运行。Netbeans正在Java 9（ea-181）下运行。大部分编译为Java 1.6标准。 - Stephen M -on strike-
@nullpointer 尝试在Java 9下运行命令行Ant，但仍然遇到相同的问题。 - Stephen M -on strike-
它是否以相同的日志失败了？ - Naman
是的，同样的失败。 - Stephen M -on strike-

发现问题出在我们自己的构建脚本中。为解决Netbeans的另一个问题，我们定义了自己的宏：

<macrodef name="javac" uri="http://www.netbeans.org/ns/j2se-project/3">

在Java 1.8中，我们没有处理modulepath属性，但现在我们已经添加了该属性：

        <attribute default="${empty.dir}" name="modulepath"/>

这似乎已经解决了我们的问题。

正如评论部分所指出的那样，当您尝试使用Java-9发布版本之前发布的Java版本执行基于的项目时，就会出现此类错误。

因此，您可以通过更新JAVA_HOME以包含Java9的jdk路径来更改计算机上安装的Java版本。

遍历项目目录，使用java -version进行确认，您将使用Java版本“9”。一旦确认，您也可以执行您的项目，问题应该得到解决。

如评论中所述，我尝试了这个方法但没有帮助。 - Stephen M -on strike-
@StephenM 但是在那种情况下，它是否也出现了相同的错误？ - Naman
同样的失败。 - Stephen M -on strike-
