问题描述
我在使用Maven和Eclipse编译器时遇到一个非常奇怪的问题.
I encounter a very strange problem with Maven and Eclipse compiler.
在Eclipse + m2eclipse中,使用以下单个类编译小型项目(原型快速入门)没有问题.
While in Eclipse+m2eclipse, I have no problem compiling a small project (archetype quick start) with the following single class.
package test.test;
import com.Ostermiller.util.CSVParser;
public class TestCaseSensitive {
CSVParser csvParser;
}
Ostermiller utils已添加到pom.xml. Eclipse Kepler编译该项目.接下来,mvn compile即开即用.
Ostermiller utils is added to pom.xml. Eclipse Kepler compiles the project.Next, mvn compile works out-of-the-box.
现在是问题,我切换到编译器3.1,并要求使用Eclipse编译器(以便能够在控制台模式和IDE模式下处理相同的编译问题).这是POM:
Now the issue, I switch to compiler 3.1 and asks for Eclipse compiler (to be able to handle same compilation issues in console mode as well as IDE mode). This is the POM :
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</build>
现在是结果:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project test: Compilation failure: Compilation failure:
[ERROR] /home/me/workspaces/4/3/ws/test/src/main/java/test/test/TestCaseSensitive.java:[3] The import com.Ostermiller cannot be resolved
[ERROR] /home/me/workspaces/4/3/ws/test/src/main/java/test/test/TestCaseSensitive.java:[7] CSVParser cannot be resolved to a type
com.Ostermiller软件包存在(它在maven默认编译器中也可以在Eclipse IDE中进行编译),但是在切换到eclipse编译器之后不存在.
The package com.Ostermiller exists (it compiles in maven default compiler as well in Eclipse IDE), but not after switching to eclipse compiler.
请注意,报告的错误路径也是错误的:
Please note that the reported error path is also wrong :
[ERROR] /home/me/workspaces/4/3/ws/test/src/main/java/...
应该是
[ERROR] /home/me/workspaces/4.3/ws/test/src/main/java/...
有人有想法吗?应该在哪里报告潜在的错误?
Has someone an idea? Where shall the potential bug be reported?
推荐答案
您是否尝试过使用tycho提供的jdt编译器?
Have you tried using the jdt compiler provided by tycho?
那会给你:
<plugin>
<!-- Use compiler plugin with tycho as the adapter to the JDT compiler. -->
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<compilerId>jdt</compilerId>
<source>1.7</source>
<target>1.7</target>
<optimize>true</optimize>
<showWarnings>true</showWarnings>
<showDeprecation>true</showDeprecation>
<fork>false</fork>
<compilerArgument>-err:nullAnnot,null</compilerArgument>
</configuration>
<dependencies>
<!-- This dependency provides the implementation of compiler "jdt": -->
<dependency>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-compiler-jdt</artifactId>
<version>${tycho-version}</version>
</dependency>
</dependencies>
</plugin>
当前tycho-version = 0.18.0
Currently tycho-version=0.18.0
