java 如何在 Netbeans 的清单类路径中包含 lib 文件夹

How to include the lib folder in the manifest classpath in Netbeans

提问by FabienB

A library that my java application uses needs looks for a file (log4j.xml) in the class path. I use netbeans to manage my project, but I can't find a way to include the lib/ folder.

我的 java 应用程序使用的库需要在类路径中查找文件 (log4j.xml)。我使用 netbeans 来管理我的项目，但我找不到包含 lib/ 文件夹的方法。

Netbeans automatically creates a MANIFEST.MF file inside the application jar and also creates a folder called lib/ which includes all dependencies. This manifest specifies a Class-Path attribute that overrides any -cp argument provided on the command line. I can select an arbitrary folder in netbeans' library panel, but it creates a sub folder in the manifest's classpath. I'd like all dependencies and the log4j.xml file inside the lib/ folder.

Netbeans 会在应用程序 jar 中自动创建一个 MANIFEST.MF 文件，并且还会创建一个名为 lib/ 的文件夹，其中包含所有依赖项。此清单指定了一个 Class-Path 属性，该属性覆盖命令行上提供的任何 -cp 参数。我可以在 netbeans 的库面板中选择任意文件夹，但它会在清单的类路径中创建一个子文件夹。我想要 lib/ 文件夹中的所有依赖项和 log4j.xml 文件。

Hopefully it's possible to do this in the IDE. I include a snippet of the auto-generated build-impl.xml file.

希望可以在 IDE 中执行此操作。我包含了自动生成的 build-impl.xml 文件的片段。

<target depends="init,compile,-pre-pre-jar,-pre-jar" if="manifest.available+main.class+mkdist.available" name="-do-jar-with-libraries">
    <property location="${build.classes.dir}" name="build.classes.dir.resolved"/>
    <pathconvert property="run.classpath.without.build.classes.dir">
        <path path="${run.classpath}"/>
        <map from="${build.classes.dir.resolved}" to=""/>
    </pathconvert>
    <pathconvert pathsep=" " property="jar.classpath">
        <path path="${run.classpath.without.build.classes.dir}"/>
        <chainedmapper>
            <flattenmapper/>
            <globmapper from="*" to="lib/*"/>
        </chainedmapper>
    </pathconvert>
    <taskdef classname="org.netbeans.modules.java.j2seproject.copylibstask.CopyLibs" classpath="${libs.CopyLibs.classpath}" name="copylibs"/>
    <copylibs compress="${jar.compress}" jarfile="${dist.jar}" manifest="${manifest.file}" runtimeclasspath="${run.classpath.without.build.classes.dir}">
        <fileset dir="${build.classes.dir}"/>
        <manifest>
            <attribute name="Main-Class" value="${main.class}"/>
            <attribute name="Class-Path" value="${jar.classpath}"/>
        </manifest>
    </copylibs>
    <echo>To run this application from the command line without Ant, try:</echo>
    <property location="${dist.jar}" name="dist.jar.resolved"/>
    <echo>java -jar "${dist.jar.resolved}"</echo>
</target>

Thanks.

谢谢。

I found a way to acheive this modifying the build-impl.xml.

我找到了一种方法来实现这个修改 build-impl.xml。

I changed:

我变了：

<attribute name="Class-Path" value="${jar.classpath}"/>

to:

到：

<attribute name="Class-Path" value="${jar.classpath} /lib"/>

The problem is that netbeans will overwrite it since this file is automatically generated.

问题是 netbeans 会覆盖它，因为这个文件是自动生成的。

Instead of editing the build-impl.xml file you should add this entry to the build.xml file. When you modify anything in your project pertaining to the building of that project, it will generate a new build-impl.xml file.

您应该将此条目添加到 build.xml 文件中，而不是编辑 build-impl.xml 文件。当您修改项目中与该项目的构建有关的任何内容时，它将生成一个新的 build-impl.xml 文件。

Here is an example of what I put in my build.xml file:

这是我放入 build.xml 文件的示例：

<target depends="init" name="-do-clean">
    <delete dir="${build.dir}"/>
    <delete file="${dist.jar}"/>
    <delete dir="${dist.dir}/lib"/>
    <delete dir="${dist.dir}/resources"/>
</target>

Since I put this in the build.xml file, it will override the "-do-clean" section of the build-impl.xml file which contains:

因为我把它放在 build.xml 文件中，它将覆盖 build-impl.xml 文件的“-do-clean”部分，其中包含：

<target depends="init" name="-do-clean">
    <delete dir="${build.dir}"/>
    <delete dir="${dist.dir}" followsymlinks="false" includeemptydirs="true"/>
</target>

Furthermore, since it is in the build.xml it won't be modified by Netbeans.

此外，由于它在 build.xml 中，因此 Netbeans 不会对其进行修改。

You can simply turn off project option Build/Packaging/Copy Dependent Library and manualy edit manifest.mf in root folder of your project (which is a template for manifest in jar file).

您可以简单地关闭项目选项 Build/Packaging/Copy Dependent Library 并手动编辑项目根文件夹中的 manifest.mf（它是 jar 文件中清单的模板）。

It seems that your problem is the "globmapper" that stores your log4j.xml file in /lib - you'd want it on the "/" or the jar.

看来您的问题是将您的 log4j.xml 文件存储在 /lib 中的“globmapper”-您希望将其放在“/”或 jar 中。
