Solve the problem of maven packaging exclusion class not taking effect

question

There is a springboot project B as a dependency of another project A. Its startup class needs to be excluded when B is packaged.

According to Baidu, you only need to add the following configuration to exclude it.

&lt;build&gt;
        &lt;!--Package project package name--&gt;
        &lt;finalName&gt;${}&lt;/finalName&gt;
        &lt;plugins&gt;
            &lt;plugin&gt;
                &lt;groupId&gt;&lt;/groupId&gt;
                &lt;artifactId&gt;maven-compiler-plugin&lt;/artifactId&gt;
                &lt;configuration&gt;
                    &lt;excludes&gt;
                        &lt;exclude&gt;**/&lt;/exclude&gt;
                    &lt;/excludes&gt;
                &lt;/configuration&gt;
            &lt;/plugin&gt;
        &lt;/plugins&gt;
    &lt;/build&gt;

However, after actual packaging, it was found that the exclusion did not take effect.

reason

1. The excluded class is imported in a certain class C. If class C wants to compile, it must compile the excluded class, so C must be excluded at the same time.

pom introduced this class, causing exclude to not take effect

Solution

Unit tests were written in Project B and annotations were used

@SpringBootTest(classes={})

So when compiling test, the startup class was forced to be compiled.

So onlySkip compilation testOr comment out

@SpringBootTest(classes={})

&lt;properties&gt;
		&lt;!--Skip the compilationtest--&gt;
        &lt;&gt;true&lt;/&gt;
        &lt;!--Skip to execute unit tests--&gt;
        &lt;skipTests&gt;true&lt;/skipTests&gt;
&lt;/properties&gt;

&lt;build&gt;
        &lt;!--Package project package name--&gt;
        &lt;finalName&gt;${}&lt;/finalName&gt;
        &lt;plugins&gt;
            &lt;plugin&gt;
                &lt;groupId&gt;&lt;/groupId&gt;
                &lt;artifactId&gt;maven-compiler-plugin&lt;/artifactId&gt;
                &lt;!--coverparent pomConfiguration--&gt;
                &lt;configuration ="override"&gt;
                    &lt;excludes&gt;
                        &lt;exclude&gt;**/&lt;/exclude&gt;
                    &lt;/excludes&gt;
                &lt;/configuration&gt;
            &lt;/plugin&gt;
        &lt;/plugins&gt;
    &lt;/build&gt;
