[英]Ant Ivy won't set compile classpath
Everything I've read online says I'm doing this right, but Ant/Ivy refuse to set my compile class path.我在网上阅读的所有内容都表明我做对了,但是 Ant/Ivy 拒绝设置我的编译 class 路径。 Here's my ivy.xml
:这是我的ivy.xml
:
<ivy-module version="2.0">
<info organisation="com.latencyzero.missiondb" module="webapp"/>
<configurations defaultconfmapping="runtime->*">
<conf name="compile" visibility="public" description="this is the default scope, used if none is specified. Compile dependencies are available in all classpaths."/>
<conf name="provided" visibility="public" description="this is much like compile, but indicates you expect the JDK or a container to provide it. It is only available on the compilation classpath, and is not transitive."/>
<conf name="runtime" visibility="public" description="this scope indicates that the dependency is not required for compilation, but is for execution. It is in the runtime and test classpaths, but not the compile classpath." extends="compile"/>
<conf name="test" visibility="private" description="this scope indicates that the dependency is not required for normal use of the application, and is only available for the test compilation and execution phases." extends="runtime"/>
</configurations>
<dependencies>
<dependency org="org.apache.logging.log4j" name="log4j" rev="2.13.3" conf="compile->default"/>
</dependencies>
</ivy-module>
And the relevant portions of build.xml
:以及build.xml
的相关部分:
<target name="resolve" description="==> retrieve dependencies with Ivy">
<ivy:retrieve/>
<ivy:cachepath pathid="compile.classpath" conf="compile" />
</target>
<target name="compile" depends="resolve" description="==> Compile Java sources">
<mkdir dir="${obj}"/>
<javac destdir="${obj}"
source="${sourceVersion}"
target="${targetClassVersion}"
encoding="UTF-8"
deprecation="${deprecation}"
nowarn="${suppressWarnings}"
debug="on"
listfiles="false"
includeantruntime="false">
<classpath refid="compile.classpath"/>
<src path="${common}"/>
<src path="${src}"/>
</javac>
</target>
When I run ant -v compile
, it downloads the log4j.jar file, and then ignores it:当我运行ant -v compile
时,它会下载 log4j.jar 文件,然后忽略它:

[javac] import org.apache.logging.log4j.Logger;
[javac] ^
Notice the classpath only has the target directory, and no jars.注意类路径只有目标目录,没有 jars。 I must be missing something obvious, but I sure can't see it.我一定遗漏了一些明显的东西,但我肯定看不到它。
So, it turns out the dependencies I should have specified were:因此,事实证明我应该指定的依赖项是:
<dependency org="org.apache.logging.log4j" name="log4j-api" rev="2.13.3">
<exclude module="log4j-api-java9"/>
</dependency>
And I need the exclude
in there or Ivy fails trying to download a module that doesn't exist.而且我需要在那里exclude
,否则 Ivy 无法尝试下载不存在的模块。
It also seems that Ivy is buggy when it comes to transitive dependencies, so I gave up on it and switched to Maven.在传递依赖方面,Ivy 似乎也有问题,所以我放弃了它并切换到 Maven。
