AspectJ Maven插件无法编译我的项目 [英] AspectJ Maven Plugin cannot compile my project

问题描述

我尝试使用aspectj maven插件与aspectj编译器编译项目，然后我尝试将类打包成war文件。不幸的是，它不适用于以下配置（pom.xml）：

I try to use aspectj maven plugin for compile project with aspectj compiler and then I try to package classes into "war" file. Unfortunately, it doesn't work with following configuration (pom.xml):

    <version>1.7.4</version>
    <type>jar</type>

mvn clean install 之后我看到以下例外情况：

After mvn clean install I see following exceptions:

[INFO] --- aspectj-maven-plugin:1.7:compile (default) @ tvbs-portlet ---
[INFO] Showing AJC message detail for messages of types: [error, warning, fail]
[ERROR] Missing message: configure.incompatibleComplianceForSource in: org.aspectj.ajdt.ajc.messages

[ERROR] AspectJ Compiler 1.8.2

    Usage: <options> <source file | @argfile>..

AspectJ-specific options:
    -inpath <list>      use classes in dirs and jars/zips in <list> as source

有人可以向我推荐一些解决方案吗？

Could anybody suggest me some solution?

推荐答案

更新：虽然我在这个答案中所说的有关AspectJ Maven配置的内容都是正确的，但是手头的具体问题的根本原因 - 糟糕的Maven依赖关系管理 - 在我的其他答案中有所描述。如果那个是接受的答案而不是这个答案会更好。

Update: While the things I said about AspectJ Maven configuration in this answer are all correct, the root cause of the concrete problem at hand - bad Maven dependency management - is described in my other answer. It would be better if that one was the accepted answer and not this one.

• 用户codelion的提示有意义，请将您的< compilationLevel> 标签（错字？） - 更改为< complianceLevel> 。


• 无需降级到插件版本1.6，您可以保留1.7。


• 也无需再次指定配置< execution> 部分，插件级别的那个就够了。


• 请注意插件1.7中的默认AspectJ版本是1.8 .2，所以也许你对1.7.4的运行时依赖性有效，但如果我是你，我也会升级那个，最好与插件版本同步。这并不是硬性要求，但我认为这是有道理的。


• 也许您甚至想要在插件和运行时升级到当前版本的AspectJ 1.8.4。这也可以通过向插件配置添加所需 aspectjtools 版本的依赖项来实现：

• User codelion's hint makes sense, please change your <compilationLevel> tag (typo?) - to <complianceLevel>.
• There is no need to downgrade to plugin version 1.6, you can keep 1.7.
• There is also no need to specify the configuration again within the <execution> section, the one at plugin level is enough.
• Please note that the default AspectJ version in plugin 1.7 is 1.8.2, so maybe your runtime dependency on 1.7.4 works, but if I were you I would upgrade that one too, optimally in sync with the plugin version. It is no hard requirement, but I think it makes sense.
• Maybe you even want to upgrade to the current version AspectJ 1.8.4, in the plugin as well as the runtime. This can also be achieved by adding a dependency to the desired aspectjtools version to the plugin configuration:

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.source-target.version>1.8</java.source-target.version>
        <aspectj.version>1.8.4</aspectj.version>
    </properties>
